مرجع مسطح 18 بوصة بطبقة Dynaflect (6068-0457-01)

The Dynaflect coating is incredibly easy to clean and doesn't leave any smudges between uses. Really solid build quality for the price, and it's been working perfectly for my initial tests.

I was a little worried about getting fingerprints on the Dynaflect coating during setup, but it wiped clean easily with no residue. The flat's surface is beautifully uniform and made aligning my interferometer a breeze.

The transmission flat arrived spotless and the Dynaflect coating is impressively uniform across the surface; I checked it under a laser and the fringe pattern was clean edge to edge. Setup took me about ten minutes to align, and it's already become my go-to for checking collimation.
