UNPACKING

The ISIS and all its accessories areshipped in a single customised pack.

Remove the ISIS system from thepacking case and check that all therelevant parts are present (seeFigure 1).

O The items shown in Figure 1 will

only be present if they are

necessary for the ISIS system

ordered (see Figure 2 and

Table 1).

STAGE 1:ASSEMBLY & ATTACHMENT

1. Refer to Figure 2 to identify the

parts and their locations.

2. Refer to the Stereo Intermediate

Adapter column (SIA) of Table 1.

If no adapter is required for the

host microscope then continue

from step 3. If an adapter is

required then the binocular head

of the host microscope should be

removed and the Stereo

Intermediate Adapter fitted

between the microscope and the

binocular head (see Figure 2).

3. Refer to the Extending

Lens(es) column of Table 1 for

selection of the appropriate

lens(es) to suit the host

microscope.

O The X value shown is the equivalent of eyepiece magnification.

4. To fit the Extending Lenses, first remove the two Protective Caps then screw the extending lenses into the exposed

threads in the centre of the parfocal control (see Figure 3). Taking care not to touch the optical disc and not to

over-tighten the Extending Lenses.

5. Refer to the Parfocal Spacer column (PSP) of Table 1. The spacers (if required) slide over the extending lenses.

6. Set the Parfocal Control to mid travel and slightly slacken the Link Knob (see Figure 3).

7. Remove the standard eyepieces from the microscope tubes. If the microscope has diopter adjustment on one or

both of its eyepiece tubes these will need to be set to the nominal zero position. If the microscope has thumb

screws to retain the eyepieces which appear to interfere with the ISIS these should be removed.

8. Slide the ISIS into the microscope tubes ensuring the assembly fits against the end of the microscope tubes.

9. Set the Eyepiece Focus Control (see Figure 3) on each eyepiece to the nominal position indicated by the dotted

line.

10. The method of initial setting of the ISIS differs slightly between microscopes with or without a zoom system. The

two methods are described in stage 2.

O If you normally wear spectacles for close work then for maximum comfort and image clarity they should also be worn

when using and setting up the ISIS.

STAGE 2:SET-UP MICROSCOPES WITH ZOOM (Refer to Figure 3)

1. Switch the microscope illumination on, view through the ISIS and if necessary adjust the Eyepiece Focus Control on

the left and right eyepieces, to obtain optimum focus of the granular optical surface of the ISIS disk.

O At this stage the ISIS power is not connected and the image from the microscope may be out of focus.

2. Connect the ISIS DC Power Supply to a suitable mains supply and connect its two jack plugs as shown in Figure 3.

Check the red power indicators are illuminated and the granular optical surface can no longer be seen when viewing

through the eyepieces.

3. View through the right hand eyepiece and focus the microscope with the zoom set at maximum magnification. Then

set the zoom to minimum magnification (do not readjust the focus control) and set the axial position of the ISIS in

the microscope tube by adjustment of the right hand Parfocal Control until the image is clear.

4. Set the zoom to maximum magnification and if the image focus is not clear, repeat step 3.

5. Without refocusing the microscope, set the zoom to minimum magnification and view through the left hand

eyepiece and adjust the left hand Parfocal Control until the image is in focus.

6. Hold the microscope binocular head and adjust the eyepiece centre distance for comfortable viewing. Lightly

tighten the Link Knob and apply gentle downward pressure on top of each ISIS unit to ensure image alignment.

Finally adjust the Eyepiece Focus Control on each side for image clarity, and the ISIS is ready for use.

STAGE 2:SET-UP MICROSCOPES WITHOUT ZOOM (Refer to Figure 3)

1. Switch the microscope illumination on, view through the ISIS and if necessary adjust the Eyepiece Focus Control on

the left and right eyepieces, to obtain optimum focus of the granular optical surface of the ISIS disk.

O At this stage the ISIS power is not connected and the image from the microscope may be out of focus.

2. Connect the ISIS DC Power Supply to a suitable mains supply and connect its two jack plugs as shown in Figure 3.

Check the red power indicators are illuminated and the granular optical surface can no longer be seen when viewing

through the eyepieces.

3. View through the right hand eyepiece and adjust the microscope focus to obtain a clear image.

4. Without adjusting the microscope focus controls check the image through the left hand eyepiece and if necessary

adjust the Parfocal Control to obtain optimum focus.

5. Hold the microscope binocular head and adjust the eyepiece centre distance for comfortable viewing. Lightly

tighten the Link Knob and apply gentle downward pressure on top of each ISIS unit to ensure image alignment.

Finally adjust the Eyepiece Focus Control on each side for image clarity, and the ISIS is ready for use.

6. To maintain optimum focus with the ISIS, POS shims should be fitted between the objective and the microscope

nosepiece for all objectives with a magnification of x20 or less (see inset of Figure 3 and Table 1).

GRATICULE FITTING (refer to Figure 4)

The ISIS has the facility for a reference graticule to be fitted to either the left or the right optical path. Select in whichside you wish to fit or exchange a graticule and proceed as follows, referring to Figure 4:

1. Disconnect the two DC Jack Plugs and withdraw the ISIS from the microscope.

2. Remove the three Case Securing Screws and carefully lift the rear cover away from the assembly.

3. Remove the three Adapter Screws and remove the Adapter.

4. Remove the Field Stop or the previously fitted Graticule Cell and store safely for future use.

5. Fit the Graticule Cell into the main casting and ensure that the gear teeth engage.

O Take care not to touch the Optical Disc or the Graticule surface.

6. Replace the Adapter and its 3 screws, ensuring the Graticule rotates freely after finally tightening the screws.

7. Replace the rear cover and the three Case Securing Screws.

8. Return the ISIS to the microscope ready for use or set up as previously described.
