- About the compatibility; for filter wheels that accept 36mm; compatible for ZWO QHY SBIG 36mm electronic filter wheel, suitable for DSLR webcam and CCD camera; use a planetary camera for planetary shooting, and a black-and-white camera for bright-field shooting
- Long-lasting lifetime; made with glass; which has been multi-coated; with an ion-assisted deposition technology; to ensure scratch resistance and stability on the central wavelength
- Get a sharp image; improve image sharpness with the addition of an UV-IR cut filter; which blocks ultraviolet and infrared transmissions; but lets the visible spectral region shine through
- How to use it; used with color filter wheels; accept 36mm unmounted filters
- With high pressure EVA case lining; comes with a plastic case; can protect the filter from scratch

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.
