IR 850nm Pass Filter – 1.25″

Threaded cell screws right onto my existing 1.25" eyepiece holder without any adapters, which made setup painless. The filter lets IR through cleanly, so my modified camera is capturing those deep red wavelengths exactly as I hoped.

Threaded perfectly into my filter wheel, and the 850nm cutoff is sharp — no visible light leaking through. I’ve been shooting landscapes with a converted camera and this filter makes the infrared pop.

Finally got some crisp IR shots with my modified camera—this filter cuts visible light cleanly and only lets through the 850nm+ range. The threaded cell screws in smooth and tight, no fiddling needed.
