كرة إرسال 6 بوصة F/1.1 - موجة 1/10

Usually I'm skeptical of specs on paper, but this 6" sphere delivered the flatness my setup needed right out of the box. The 1/10 wave PV held up across multiple test runs, and the mounting edge has a satisfyingly solid feel. Interferograms came out cleaner than I've seen in a while.

The 1/10 wave PV spec is no joke—my interferograms are cleaner than anything I've gotten from cheaper spheres. The 6-inch aperture covers my larger test pieces without stitching, and the F/1.1 speed saves me time on every setup. Just wish the mounting threads were a bit more standard, but the optica

I was blown away by how clean the 1/10 wave PV specification made my interference patterns during a test run. The 6" aperture on this F/1.1 sphere gave me exactly the coverage I needed for larger optics, and it held alignment without any drift.
