2.2.2 Insertion of MC 2.5

× Photo Reticles in the Eyepiece

A focusing eyepiece with photo reticle must be

used if focusing is not to be performed through

the viewfinder of the SLR camera.

The MC 2.5

× photo reticles are inserted into the

eyepieces 10

× foc. of the relevant microscope.

The photo reticles (2-2/1) from Carl Zeiss have

been adhered to screw-in mounts (2-2/2) to allow

easy replacement.

To insert the photo reticles, just unscrew the

empty reticle mount and replace it with a new

mount (2-2/2) containing the required photo

reticle (2-2/1).

The slight image shift caused by the additional

path through the glass is taken into account on

the diopter scale by the fact that the zero point

position is indicated not by the white dot W (2-

2/W) but by the red dot (2-2/R).

For focusing eyepieces without photo reticle ⇒ set diopter zero position to the white dot (2-2/W), and

for focusing eyepieces with photo reticle ⇒ set diopter zero position to the red dot (2-2/R).

☞

If photo reticles are inserted into the unscrewed mount by the customer, attention must be

paid to the labeling being visible the right way up after insertion.

2.2.3 Focusing of Eyepieces through the Binocular Tube

• Insert the eyepiece with photo reticle in one side of the binocular phototube and align the photo

reticle with the microscope camera (microscope camera normally pointing to the observer).

• Use the eyepiece to focus on the line figure of the photo reticle.

• Use the focusing drive to focus on the microscope image of the specimen through the eyepiece set as

described above.

• Then use the eyepiece without photo reticle to focus the microscope image for the second eye. The

position of the focusing drive on the microscope stand must not be changed.
