Long Working Distance objectives, similar to Mitutoyo, NIR transmissive.
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.

DIN threading, allows use on many scopes with DIN nosepiece. Because of larger diameter compared to DIN objectives you will in many cases only be able to install 2 objectives. Supplied adapter allows use on Mitutoyo nosepieces, too.

Mitutoyo threads, Mitutoyo compatible nosepiece needed or you need to use an adapter.
Or here from different supplier  showing
