Accessory - Extension ring 0.2 mm
Characteristics
- reduces the minimum object distance (MOD) for entocentric lenses
- reduces the working distance for telecentric lenses
- enlarges the magnification
- shortening the working distance by approx. the thickness of the intermediate ring divided by the square of the magnification of the respective objective lens
- compatible with C-mount and CS-mount lenses
- usable in any combination
