Emily Q. ★★★★★

Cut this 3mm RG850 to size for a long-pass filter in an IR photography project, and it blocks visible light cleanly with no pinhole leaks. The thickness feels sturdy enough to handle repeated handling during testing.

Ryan R. ★★★★★

Installed this 3mm RG850 in my fluorescence setup and the sharp cut-on is exactly what I needed — no bleed-through from shorter wavelengths. Works perfectly as a longpass for blocking everything below 850nm.

Jason T. ★★★★★

Finally got around to testing this 3 mm thick RG850 filter and the cut-on is exactly where I needed it for my NIR setup. The passed signal is clean with no noticeable scatter even at steep angles.
