كرة نقل 4 بوصة، F/0.75، مجموعة، Dynaflect -- مطلية

Setting up this F/0.75 sphere for a cavity alignment test was remarkably quick, and the optical quality through the coated assembly is exactly what I needed for clean interferometric data.

The Dynaflect coating on this 4" sphere noticeably reduces ghost reflections during interferometry measurements, which cleaned up my fringe contrast. I've been using it on a few setups and the assembly feels solidly built for the price.

The Dynaflect coating on this 4" sphere really cuts down on stray light compared to my old uncoated unit. Setup was straightforward and the F/0.75 aperture gives a nice tight focus for my interferometry tests. It's working exactly as needed for my optical bench.
