Lyte-MV 2 5V Analogue Userguide
2. Product OperationA: CW ModeTo operate laser in CW mode the Red ,Black, Yellow & Blue leads should be connected to the following:
(Warning do not apply voltages greater then 5.5Vdc to the Blue enable lead or permanent damage will accrue to the laser module. See section C for further detail).
Pin Lead Description Lyte-MV 2
1 Red Lead + Volts +5 Vdc (±10%)
2 Black Lead 0 Volts 0 Vdc
3 Yellow Lead Modulation + Vdc
4 Blue Lead Enable +V Supply if not using as enable switch
B: Linear Modulation FunctionTo linearly modulate the laser any modulation signal up to 200kHz with an amplitude of 0V to +1Vdc can be applied to Yellow Lead.
C. Linear Intensity ControlAlternatively the Yellow Lead can be used for a linear power control function. In this situation,the laser power is determined by a voltage applied to the Yellow Lead, 0V turning the laser offand +1Vdc giving maximum power, with linear trend between (see linear intensity graph).
Pin Lead Description Lyte-MV 2
1 Red Lead + Volts +5 Vdc (±10%)
2 Black Lead 0 Volts 0 Vdc
3 Yellow Lead Modulation Input Modulation Signal 0 to +1 Vdc
4 Blue Lead Enable +V Supply if not using as enable switch
Pin Lead Description Lyte-MV 2
1 Red Lead + Volts +5 Vdc (±10%)
2 Black Lead 0 Volts 0 Vdc
3 Yellow Lead Modulation Input Modulation Signal 0 to +1 Vdc
4 Blue Lead Enable +V Supply if not using as enable switch
D. Operating with a PS-1 5 VoltIf you have purchased a Lyte-MV 2 with a 100V/240V to 5Volt PS1 you will have the following items:
Lyte-MV 2 LaserLyte-MV2 to PS-1 Cable100V/240V to 5 Volt PS-1 Main socket to PS-1 Power Lead (UK, Euro or US)
1. Connect the DC jack on the Lyte MV 2 to PS1 cable into the DC socket on the PS-1 power supply and screw binder connector into the connector on the end of laser.2. Connect IEC plug to PS-1 power adaptor.3. Plug the mains plug into a mains socket.4. Switch on the power supply via key switch (If you have purchased a 5V PS1 fitted with a key switch) or switch on at the mains socket.

D) Setting the Output Power Via a ResistorThe control wire has a 10k Ohm input impedance connected to an internal 1V source which is used as the reference for the factory set power. Measuring the voltage between the Yellow and Black wires with a high (>10M Ohm) impedance voltmeter, will give a reading of 1 V ± 2%. Connecting a 10k Ohm resistance between the Yellow and Black wires will result in the reading falling to 0.5V and the light output falling to half the factory set power. Other outputs between 0
and the factory set power can be achieved with a single resistor Rx by using the formula:
Where Po is the required power outputas Pfs is the factory set power
RX = Po* 10K PFs - Po
Enable Switch (Blue Lead)An on/off switch function is available via the blue wire. Applying 0V will switch the laser off whilst applying V supply leaves the laser on. This is partially useful for safety interlocks or enable switch’s required for laser safety systems. A TTL switch can also be utilised via this lead. TTL High = on and TTL Low = off. Maximum frequency is typically 100 Hz. If not using these function please connect the lead to the V supply or the laser will not switch on.
To ensure the lifetime and the stability of the laser it is recommended that it is mounted in a suitable heat sink/mount. The case temperature should be kept within the specified range at all times, failure to do this could result in shortened lifetime or catastrophic failure. As a guide, laser diode lifetime decreases by a factor of two (approx.) for every ten degree increase in operating temperature.
To assist with this requirement the Lyte-MV 2 has a threaded front barrel (M18x1) which can fit to a bulkhead or threaded hole. The direct contact of the barrel to the mount helps to ensure heat sinking and improve laser diode lifetime. Alternatively a version of Global Laser’s heavy duty clamp which has a thread arm is available. To further assist mounting the module is supplied with two nut’s which are fitted to the front barrel. A tool to fit a 24mm nut is required for adjustment. To further improve reliability the barrel is isolated from the laser diode supply voltage at all times.
3A Mounting the Lyte-MV 2 in the Heavy Duty Clamp1. Un-tighten allen screw A (see drawing B) with the supplied allen key2. Screw the laser into the mounting hole (see drawing B) and tighten allen key A.3. For vertical adjustment of the laser un-tighten grub screw A (see drawing B). This will allow the section mounting the laser to be adjusted. When the vertical posting is complete re-tighten grub screw A. 4. For horizontal adjustment of the laser un-tighten grub screw B (see drawing B). This will allow the main body of the mount to be moved. When the horizontal positing is complete re-tighten grub screw B. 5. To secure the heavy duty clamp to a surface machine screw or studs can be used in conjunction with the base section (see drawing B for thread details).
3B Mounting the Lyte-MV 2 in the Heavy Duty Clamp with the Magnetic Base1. Un-tighten allen screw A (see drawing B) with the supplied allen key2. Screw the laser into the mounting hole (see drawing B) and tighten allen key A.3. For vertical adjustment of the laser un-tighten grub screw A (see drawing B). This will allow the section mounting the laser to be adjusted. When the vertical posting is complete re-tighten grub screw A. 4. For horizontal adjustment of the laser un-tighten grub screw B (see drawing B). This will allow the main body of the mount to be moved. When the horizontal positing is complete re-tighten grub screw B. 5. To secure the magnetic base to the heavy duty clamp simple screw the stud on the top of the magnetic base into the centre hole in the base of the heavy duty clamp until tight.6. Remove the keeper from the magnetic base and place on a ferrous surface to secure.
3. Mounting
5. Focus Adjustment
4. Cleaning The Optics
The laser will have been focused and tested at the nominal working distance requested at the time of order. If you did not specify a distance or were unsure at the time of order it will be focused at 300mm (11.81 inches).
Should you need to adjust the focus (alter the spot size line thickness/pattern thickness) please follow the simple instructions below:
Turn the focusing control (brass knurled section) at the middle of the laser (see diagram A) clockwise / anti clockwise until the desired focus is achieved. As a rule of thumb if you wish the focus to be at shorter distance from the laser than it is currently set to turn the focus control anti-clockwise. If you wish the focus to be at longer distance from the laser then it is currently set to turn the focus control clockwise.
The Lyte MV 2 is protected against dust and fluid with an ingress protection (IP) rating of 67. The protection level is defined IEC60529 as below:
Please Note that liquids are defined as water. Oil or chemicals may require further protection.
It is recommended that when the Lyte-MV 2 is not in use the supplied protective cap is placed over the optics to reduce the risk of the being contaminate by dirt.
If the laser pattern becomes fuzzy or unclear, please check the following:1. Check the laser is in focus (see section 5).2. Verify the protective window on the front of the laser is clean
If the window is contaminated, the lens can be cleaned with an optical cloth or cleaning kit.
IP First Number Protection against solid objects
6 Totally protected against dust
IP Second Number Protection against liquids
7 Protected against the effects of immersion between 15cm and 1 meter
