20X 0.40NA AF Mirau objective

I was worried about compatibility, but the SKU 6300-0595-01 matched my system perfectly, and the 20X magnification with 0.40NA gives me crisp interference fringes on smooth surfaces.

The 0.40NA aperture on this objective lets me resolve finer fringe patterns than my old 10X unit. It locks onto surfaces cleanly with the Mirau interferometer setup, and the autofocus feature saves me from constant manual tweaking.

Took a chance on this 20X Mirau objective for our shop’s metrology setup, and the 0.40NA really delivers crisp fringe patterns even on slightly tricky surfaces. The whole assembly feels solid and threaded on without any wobble. Definitely money well spent for the upgrade.
