Lower Cost Super Long Working Distance Plan Apochromat objectives.
Lower Cost Long Working Distance Plan Apochromat objectives with 95 mm parfocal length for visible range.
Image above shows currently available objectives from 1X - 500X.  
Prices increase in Asia relentlessly and this offer is based on introductioary pricing received some days ago, valid till the end of this year.
Parfocal Distance = 95mm, with Mitutoyo  thread (26 mm x 36tpi).
Infinity type for use with F = 200mm tube lens, spectral transmission 400nm to 700nm.
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.
The 250X and 500X objectives run into well known resolution limits on smallest wave length in visible light. But if the working distances for 100X, 150X, and 200X are acceptable then the relatively high NA might be attractive.
