Gooch and Housego offers

1000-W DXW, 200-W, and

45-W lamps as standards

of spectral irradiance, total

irradiance, illuminance, and

color temperature. These

lamps have tungsten

coiled-coil filaments

enclosed in a small quartz

envelope. The lamp

standards can be obtained

with spectral irradiance

calibrations over all or part of the 250 to 2500 nm

wavelength region. In addition, the 1000-W DXW and

200-W lamps can be calibrated out to 4500 nm.

The spectral irradiance standards issued by Gooch

and Housego are based on

the National Institute of

Standards and Technology

(NIST) Spectral Irradiance

Scale for the wavelength

range of 250 to 2400 nm

and on a blackbody for the

wavelength range above

2400 nm. The NIST Scale

has an uncertainty (k=2) of

0.63% in the visible, 1.56%

in the ultraviolet at 250 nm, and 0.31% in the infrared at

2000 nm.

Calibration of the 1000-W

DXW and 200-W lamps over

the wavelength range of 250

to 2400 nm are available with

two levels of accuracy: high-

accuracy and super high-

accuracy. The High-Accuracy

Standards of Spectral

Irradiance issued by Gooch

and Housego have a transfer

uncertainty (k=2) relative to

the NIST Scale of ± 1-2%. The

Super High-Accuracy Standards have a transfer uncertainty

relative to the NIST Scale of ± 0.5%.

Method of Calibration The instrumentation and methods used by Gooch and

Housego to transfer calibrations from a standard of spectral

irradiance to an uncalibrated lamp is patterned after that

used at NIST. The measurement procedure employs the

highly accurate wavelength-by-wavelength method of

comparison (Figure 1). This minimizes the errors associated

with setting the lamp current, distance, wavelength, and

repeatability.

In this technique, both lamps (standard and test) are

operated at the same distance. The spectral irradiance of

both lamps is measured at a set wavelength by translating

the double monochromator along the optical bench to view

each source. A wavelength-by-wavelength comparison is

made at all of the NIST calibration wavelengths.

The High-accuracy Standards are calibrated by comparison

to a standard that was calibrated directly against a NIST

standard. The Super High-Accuracy Standards are

compared directly to a NIST standard.

Optional Accessories Gooch and Housego offers several accessories to enable the

user to realize the high accuracy assigned to its NIST-

traceable standards. These accessories are designed to

minimize errors due to current setting, alignment, and

orientation.

The OL 410 and OL 83A Programmable DC Current

Sources are specifically designed for operating the lamp

standards at the exact calibration current. (See Bulletin 121

for further details).

There are six dimensional variables involved in the NIST

recommended alignment of a lamp relative to the instrument.

The OL 56, OL 57, and OL 57W Lamp Holders and OL 63

Adjustable Lamp Holder Mount (Figure 2) are designed to

allow the user to control the physical positioning of the lamp

including distance, horizontal distance, vertical distance, pitch

(tilt), yaw (rotation), and roll.

GENERAL DESCRIPTION

The OL 345 Calibration Standard consists of a 45-watt tungsten-halogen lamp and a removable 2-inch diameter flashed-opal diffuser mounted in an air-cooled, machined, cylindrical housing. With the diffuser in place, the uniform, 15.5 cm² radiating source serves as a standard of spectral radiance over the wavelength range of 350 to 1100 nm and as a standard of luminance. When the diffuser is removed, the OL 345 serves as a standard of spectral irradiance from 250 to 2500 nm and as a standard of illuminance. The OL 345 can also be obtained with the source operating at a specified color temperature. A filter holder is provided for inserting 2-inch square filters into the unit between the lamp and the diffuser. Spectral shaping filters for simulation of various types of CRT phosphor screens and for obtaining color temperatures up to 6000 K are available. Narrow band interference filters for obtaining discrete spectral

radiances and irradiances are also available.

APPLICATION

The OL 345 is a rugged, versatile radiometric and photometric standard capable of accurately calibrating a large variety of light measuring instrumentation. When the 2-inch diameter opal diffuser is attached, the unit is ideal for calibrating such instrumentation as tele-photometers, microphotometers, telespectro-radiometers, etc. When the opal is removed, the absolute calibration of spectral irradiance and illumination measuring instrumentation is easily accomplished.

OL 345

Radiometric and

Photometric

Calibration Standard

The ability to insert either narrow band interference filters or spectral shaping filters in the beam enables the calibration of various radiometers and photometers to be made quickly and accurately.

The OL 46D Current Source for Deuterium Lamps is

specifically designed to operate the OL UV-40 and OL

752-12 deuterium lamp standards of spectral irradiance.

The OL UV-40 must be operated at the same current used

during the calibration in order to realize the calibration

accuracy. Accordingly, the OL 46D provides a constant

lamp current of 300 mA with an uncertainty of ± 0.1%. It is

also an ideal current source for the OL 740-20 and OL

750-20 deuterium sources.

The OL 46D features complex automatic lamp starting and

operating supplies. Its dual filament design can operate

lamps with high or low filament current requirements.

When the supply is turned on, a current is supplied to the

starting filament. After 20 seconds, the regulated filament

current is reduced 40% of the initial value and the high

voltage circuit is switched on. Following the high voltage

pulse, the lamp arc strikes and a precision lamp current is

established. The circuit is designed to provide a stable,

reliable discharge without subjecting the lamp to undue

stress.

The OL 46D regulated power supply maintains its

accuracy during power line transients of ± 10%. The

supply will also operate over a ± 10% load variance, which

allows it to accommodate different operating voltages from

one lamp to another.

Two plug-in, pre-aligned irradiance standards are available for

accurately calibrating the OL 754 Spectroradiometer for spectral

irradiance response. The "plug-in/ pre-aligned" concept

eliminates tedious and time consuming set-up and alignment

normally associated with spectroradiometric standards as they

merely attach to the OL 754's integrating sphere cosine

receptor. Both standards, with appropriate baffles, are mounted

in pre-aligned/holder mounts. Machined, cylindrical covers are

provided to protect the lamps when not in use.

OL 752-10 Tungsten Plug-In

Standard

The OL 752-10 can be obtained with

spectral irradiance calibrations over

the wavelength range of 250 to 2500

nm. It consists of a compact, 200-W

tungsten-halogen lamp operating at a

color temperature of about 3000 K.

The short working distance of 13 cm

results in irradiance levels significantly higher than that normally

obtained with higher wattage standards. The combination of

greater precision in optical alignment and higher irradiance

levels provides for a more accurate calibration of the

spectroradiometer. Calibration of the OL 752-10 is based on the

NIST High-Accuracy Scale of Spectral Irradiance. The NIST

Scale has a reported uncertainty that varies from ± 2% at 250

nm to ± 1% in the visible. The OL 752-10 has a transfer

uncertainty relative to the NIST Scale that varies from ± 1.5% in

the ultraviolet to ± 1% in the visible-near infrared.

OL 752-12 Deuterium Plug-In

Standard

The OL 752-12 is calibrated for

spectral irradiance over the

wavelength range of 200 to 400 nm.

It uses a stable, 40-W deuterium

lamp. When mounted in the plug-

in/pre-aligned housing, the working distance is 10 cm. This

short working distance generates considerably higher irradiance

levels than that obtained with conventional ultraviolet irradiance

standards. The OL 752-12 is calibrated relative to the NIST

Ultraviolet Irradiance Standard for the region below 250 nm and

to the NIST High-Accuracy Scale of Spectral Irradiance for the

250 to 400 nm region. The NIST Ultraviolet Irradiance Standard

has an uncertainty that varies from ± 7.5% at 200 nm to ± 5% at

250 nm. The OL 752-12 has a transfer uncertainty relative to

the NIST Scales that varies from ± 3% at 200 nm to ± 1.5% at

400 nm.

The OL 83A is a microprocessor-controlled, precision

DC current source specifically designed to accurately

operate tungsten filament lamp standards and

calibration sources. The power output range is 10 to

1000 watts. The unit features:

- Output current accuracy of ± 0.01% or better

- Controlled ramp up/ ramp down of the lamp current

- Simultaneous digital readout of lamp current, voltage,

and power

- Ability to set lamp current, voltage, or power

- Lamp "library" for storing and recalling the operating

parameters & description for up to 10 different lamps.

The user-defined operating parameters include lamp

current, voltage or power, current limit, calibration due

interval & lamp hours. A separate elapsed time meter

keeps track of the lamp hours for each of the 10 lamps.

A calibration due warning message will appear upon

power up when the lamp hour’s limit is exceeded and/or

one (1) year has elapsed since last calibration.

- RS-232 (standard) and IEEE-488 (optional) computer

interface

Tungsten lamp standards must be operated at their

specified calibration current in order to realize the

accuracy of the standard. A small error in setting the

lamp current can induce a sizeable, wavelength

dependent error in the spectral output of the lamp. The

OL 83A enables the lamp current to be set to an

accuracy of better than ± 0.01%, a factor of about 25

better than most other commercial power supplies,

which are typically 0.25%. The advantage of the OL

83A's increased accuracy is illustrated in the table

In order to eliminate electrical shocking of the lamp due to high initial current surges, a ramp function is used to control the turn-on current rise. Once the instrument is turned on, the current automatically increases at a slow, safe rate until the set current is reached. A fail-safe, shut down circuit protects the lamp standard against any equipment malfunctions. The current sources will maintain their accuracies while experiencing ± 10% fluctuations in line voltage and ±10% variance on the load voltage. These features effectively compensate for transients in the power line and variations in resistance from one lamp to another. The power supplies are packaged in a chassis suitable for mounting in a 19" cabinet rack.

Optional PCS Software Package The PCS Software Package is available for the OL 83A Programmable Current Source (PCS) and consists of two

instrument control software applications and a software development kit. Instrument control applications allow the user

to operate all of the PCS's functions from a host computer. The primary application is based upon ActiveX technology.

A secondary LabVIEW application is also provided.

The software development kit includes an ActiveX control, which functions as an instrument driver and user interface.

Additionally, programmers may develop custom applications from suitable ActiveX containers such as Excel, a Visual

Basic executable program, or C++. This is a very useful feature, especially for controlling multiple instruments and

custom reporting or logging.

Another component of the software development kit is the LabVIEW source code (vi's). These vi's function as

LabVIEW instrument drivers for customers who own LabVIEW and wish to develop their own custom applications in

this development environment.

- Software applications include the real-time display of lamp parameters, including current, voltage, wattage, usage

hours, current limit, and lamp description.

- Uploading and downloading of a lamp parameter set, which contains information on a particular lamp (current,

voltage, wattage, usage hours, current limit, and lamp description).

- Uploading and downloading an entire lamp library file, which contains up to 10 separate lamp parameter sets.

- Logging of the lamp's current and voltage to a user-specified data-logging file at regular user-defined intervals

(LabVIEW application and software development kit).

The uploading/downloading features allow an unlimited number of lamps to be tracked individually!

Gooch and Housego offers 1000-W FEL type lamps as

standards of spectral irradiance, total irradiance,

Illuminance, and color temperature. These lamps have a

tungsten coiled-coil filament enclosed in a small quartz

envelope. The lamp bases have been converted to a

medium bi-post base as recommended by the National

Institute of Standards and Technology (NIST). This special

lamp base improves alignment accuracy, which minimizes

uncertainties due to positioning and orientation of the lamp.

The spectral irradiance standards issued by Gooch and

Housego can be obtained with spectral irradiance

calibrations over all or part of the entire 250 to 4500 nm

wavelength region. Calibrations are based on the NIST

Spectral Irradiance Scale for the wavelength range of 250

to 2400 nm and on a copper freezing point blackbody for

the wavelength range above 2400 nm. The NIST Scale

has an uncertainty of 1% in the visible, 2.5% in the

ultraviolet at 250 nm, and 3% in the infrared at 2000 nm.

Calibrations over the wavelength range of 250 to 2400 nm

are available with two levels of accuracy: high-accuracy

and super high-accuracy. The High-accuracy FEL

Standards issued by Gooch and Housego have a transfer

uncertainty relative to the NIST Scale of ± 1%. The Super

High-accuracy FEL Standards have a transfer uncertainty

relative to the NIST Scale of ± 0.5%.

Method of Calibration

The instrumentation and technique used by Gooch &

Housego to transfer calibrations from a standard of spectral

irradiance to an uncalibrated lamp is patterned after that

used at NIST. The measurement procedure employs the

highly accurate wavelength-by-wavelength method of

comparison (Figure 1). This minimizes the errors

associated with setting the lamp current, distance,

wavelength, and repeatability.

In this technique, both lamps (standard and test) are

operated in series at the same current and at the same

distance. The spectral irradiance of both lamps is measured

at a set wavelength by translating the double monochromator

along the optical bench to view each source. A wavelength-

by-wavelength comparison is made at all of the NIST

calibration wavelengths.

The high-accuracy FEL standards are calibrated by

comparison to a standard that was calibrated directly

against a NIST standard. The super high accuracy FEL

standards are compared directly to a NIST standard.

Optional Accessories

Gooch & Housego offers several accessories to enable the

user to realize the high accuracy assigned to their NIST-

traceable standard. These accessories are designed to

minimize errors due to current setting, alignment, and

orientation.

The OL 83A programmable Current Source is specifically

designed for operating the 1000-W lamp standards at the

exact current.

There are six dimensional variables involved in the NIST

recommended alignment of a lamp relative to the

instrument. The OL 61 Lamp Holder, OL 62 FEL Alignment

Jig, and OL 63 Adjustable Lamp Holder Mount (Figure 2)

are designed to allow the user to control the physical

positioning of the lamp including distance, horizontal

distance, vertical distance, pitch (tilt), yaw (rotation), and

roll.
