8.7 Magnification changer

Optionally, a coded magnification changer can be used, which is manually operated.

On the knurled ring, the following magnification factors can be set:

8.8HC P 1x/1.6x tube optics with Bertrand lens (encoded)

These optics were developed especially for po- larizing microscopy; however, they can also be used for all other methods.

Iris diaphragm in the intermediate image for masking out small particles (15 m for the 100x objective).

Built-in, depolarized quartz plate:

This plate prevents interference colors, which are caused by tube prism polarization effects (pseudopleochroism), when the analyzer is con- nected and the polarizer is switched on; howev- er, it only prevents this when the 1x tube factor is being used.

When using the 1.6 fix tube factor, make sure that the useful magnification for high objective magnifications and apertures (objective aper- ture x 1000) is not exceeded to the point that overmagnification causes a blurry image im- pression.
