When change of reflected-light fluorescence and transmitting Nomarski
differential interference is frequently done and simultaneous observation
is also required, it is recommended that high abrasion-resistant analyzer
slider (U-ANH) is used instead of analyzer (U-AN).
When change of reflected-light fluorescence and transmitting Nomarski
differential interference is frequently done but simultaneous observation
is not required, it would be convenient if mirror unit (U-MDICT3) for
differential interference is attached at front side turret, instead of using
analyzer (U-AN or U-ANH).
If the fluorescent mirror unit is changed to differential interference mirror
unit, the analyzer comes into light path together so that the changeover is
easy.
