* Shading may occur in the low zoom magnification range.
Increasing contrast of the OCC observation image
For observations of the OCC observation image with higher contrast, remove the filter dropping ring (attached to the base
optical path immediately under the grass plate). The contrast can be increased by removing the filter dropping ring that
contains a diffuser plate to control excess contrast for OCC.
45-mm dia. filter
A 45-mm dia. filter (no thicker than 5 mm) can be dropped onto the filter dropping ring (attached to the base optical path
immediately under the grass plate).
Tap holes for attaching accessories
The base's top board has tap holes for attaching various
accessories. Tap holes
