Lower Cost Super Long Working Distance Plan Apochromat objectives.
Image at left shows currently available objectives from 2-50X with 2X on the righthand side. These are essentially 5 separate images combined into one. Consequently objectives are at different scale! For dimensions please click on link unter image (on detail page).
A while ago the manufacturer did change the outside look from black coating to a chrome finish, 2X is the last one still available in black coating.
Prices increase in Asia relentlessly. Adjustment is based on pricing received June 29.
Parfocal Distance = 95mm, with Mitutoyo thread (26 mm x 36tpi).
Infinity type for use with F = 200mm tube lens, spectral transmission 400nm to 800nm.
Many parameters like parfocal length, use of f = 200 mm tube lens, and outside dimensions match the Mitutoyo part while other properties are only slightly different.
Chromatic aberration is corrected for red, blue, and yellow by using an apochromatic objective lens as compared to a standard achromatic objective lens with correction for red and yellow only.
