Plan apo 20X 0.42/20MM 3MM coverglass corr nirobjective


Subject: Plan apo 20X 0.42/20MM 3MM coverglass corr nirobjective
Super Long Working distance Plan Apochromat Objective, 20X, 95mm parfocal distance, infinity tubelength, 34mm diameter, RMS Thread, NIR transmissive, with 3 mm cover glass correction. Other correction values on request, please contact us.
This is a new product with a 1 year warranty.
For many applications this objective will work as a replacement for Mitutoyo part 378-824-4.
RMS to Mitutoyo thread adapter is included.
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. And you won't need to give up performance.
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.
Objectives are strain-free and optimized for bright field illumination (incident illumination parallel to optical axis), making them ideal for in-line illumination applications.
Infinity correction is by way of a secondary or tube lens with a standardized focal length of 200 mm.
* Working Distance (mm): 20.2
* Flat image plane over entire field of view
* Standard RMS threads, Mitutoyo adapter included
50X with 3mm cover glass correction
