F/35 Diverger 4"

The 1/10 wave PV rating on this 4" diverger really delivers—my interferometer readings are noticeably cleaner than with my old optic. It’s a solid piece of glass that does exactly what it’s supposed to, no fuss.

The F/35 4-inch diverger has excellent beam shaping in my optical setup. I was pleased with how clean and consistent the wavefront came out, especially for collimation testing.

The 1/10 wave PV rating is what sold me, and it doesn't disappoint—fringes come out clean and stable every time. The 4-inch aperture handles my larger test pieces without any clipping, which is a huge relief. Set-up was straightforward, and it's been rock solid on the bench for the past week.
