كرة نقل 2 بوصة 10.6 ميكرومتر - f/0.75

The 1/20th wave PVr specification at 10.6 µm is spot-on for my interferometry setup—clean fringes right out of the box. It mates perfectly with the 6500-0772, and the build feels robust for a 2-inch sphere.

The 1/20th wave specification is what sold me, and the interferograms confirm it's holding up exactly as promised at 10.6 µm. Mounting it with the 6500-0772 was straightforward, and the f/0.75 gives me a nice tight focus for my testing setup. Just wish it came with a dust cap, but that’s a minor gri

The f/0.75 aperture on this sphere really lets me gather light efficiently for my 10.6 micron setup, and the 1/20th wave accuracy at that wavelength is spot on for what I need. It paired seamlessly with the required 6500-0772 mount, and the build feels solid enough for daily lab use.
