36mm UV/IR Cut Unmounted Filter

Improve image sharpness by blocking Ultraviolet and Infrared transmissions. The IR (700nm to 1100nm) and UV (300nm - 400nm) part of the spectrum are invisible to human eyes, but not to most CCD and other digital cameras, which are sensitive to 300nm to 1100nm. This filter reflects heat radiation and provides great protection against dust. The 36mm Unmounted UV-IR Cut Filter is made with glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength or CWL. This UV-IR Cut filter is designed to be used with color filter wheels that accept 36mm Unmounted filters. 95% transmission at visible spectral region 420-680nm highly passing the major nebula emission lines of H-Alpha 656nm, SII 672nm, and NII 654nm and 658nm. Each filter comes with a plastic case with a high-pressure EVA case lining.
