The Optolong UV-IR Cut Filter is designed to block ultraviolet (UV) and infrared (IR) wavelengths, allowing for sharper astrophotography images.
UV Blocking: Blocks UV wavelengths from 300-400nm, reducing haze and improving image contrast.
IR Blocking: Blocks IR wavelengths from 700-1100nm, reducing thermal noise and improving image sharpness.
Visible Transmission: Transmits 95% of visible light from 420-680nm, including crucial nebula emissions like H-alpha and SII.
Glass Quality: Made with Schott optical glass, polished to precision tolerances.
Mounting: Available in 1.25", 2", and 36mm sizes, with threaded inserts for easy mounting.
Coating: Fully multi-coated for minimal reflection and maximum transmission.
