Sfera di trasmissione da 4" F/3.3 - 1/10 onda

The wavefront error on this 1/10 wave PV sphere is impressively low—it cleaned up the fringes on my interferometer test stand noticeably better than my older reference. Setup was straightforward with the standard configuration, and the 4-inch aperture works perfectly for my small optics.

Finally, a transmission sphere that actually matches its spec sheet—the 1/10 wave PV rating showed up clean on my interferometer runs. The 4" aperture at F/3.3 is fast enough for testing my larger optical systems without swapping setups. Mounting was straightforward, and the Standard configuration k

The ZYGO 1/10 wave PV rating holds up even on my big 4-inch F/3.3—interferogram fringes came out perfectly straight on the first try. Definitely the sharpest reference I've used for collimation checks.
