Customer Reviews (4.8 / 5 · 5 reviews)

Lucy ★★★★★

The 3mm thickness gives it real heft in the filter holder, and it’s cut cleanly to the Ø dimension I ordered. Slotted it into my optical setup and the cutoff is sharp where I needed it. Exactly what I was hoping for.

Christopher ★★★★★

Used this RG9 as a longpass in my spectroscopy rig, and the 3mm thickness gives it a nice solid feel that doesn't flex under the mount. It cut off exactly at the right wavelength for my setup, no stray light issues.

Edward I. ★★★★★

Snapped this into my filter holder for IR work and the cutoff is exactly where I expected it. Glass arrived clean with no chips or haze, and the polish is good enough that I don't see any scatter in my beam.
