The Player One UV/IR Cut 2″ – Luminance filter (SKU: POA-AH-UVIR-CUT-2) blocks ultraviolet radiation below ≈400 nm and infrared radiation above ≈700 nm, while transmitting only the visible spectrum. This ensures faithful colors and sharp stars in L-RGB images and protects the telescope from blur caused by longer IR wavelengths when working with lens optics.

Key Features of the UV/IR Cut 2″ Filter

• wide transmission band 400 – 700 nm (>95%) – ideal for the L channel in L-RGB sets
• effective UV and IR blocking (<0.1% transmission below 400 nm and above 700 nm)
• double multi-layer anti-reflective coatings (hard-coated) – high contrast, scratch and moisture resistance
• λ/4 class optical glass, surface parallel ≤ 30″ – minimal wave front distortion
• 2″ aluminum frame (M48 × 0.75) with blackened edges and thin threaded bezel – no vignetting in full-frame tracks
• compatible with Player One FD MAX filter wheels and drawers and most 2″ accessories on the market

The Cut Player One UV/IR filter is an indispensable tool in every L-RGB set and when taking color photos with refractors, catadioptrics or Newtons with a co-corrector. It also protects the camera matrix from IR overheating with bright objects (e.g. the Sun with the appropriate ERF). Give your photos perfect sharpness and natural colors - with one filter.
