Various observation methods
4-1 Reflected light differential interference contrast (DIC) observation
For the DIC (Differential Interference Contrast) observation, following units are required.
· Analyzer: GX-AN360 or GX-AN
· Polarizer: GX-PO or GX-POTP ( PO surface)
· DIC slider: U-DICR (standard), U-DICRH* or U-DICRHC
* When using the DIC slider U-DICRH to perform the sensitive color observation, combine the polarizer GX-POTP.
· Revolving nosepiece (equipped with the DIC slider insertion slot): U-D5BDRE, U-D5BDREM or U-D6REM
·
The performance of the polarizer may be deteriorated if it is exposed to the light for a long period
(approx. 2,000 hours continuously). If this happens, replace the polarizer.
·
When using the mercury lamp housing, be sure to use the U-25L42 filter to prevent the polarizer from
tarnish.
