Baader Planetarium has introduced the world's finest UV/IR cut filter. This filter is a must for all digital imaging with digital cameras, CCD cameras and modified webcams. It's also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc). Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). Like the Baader Planetarium Contrast-Booster, the UV-IR-Cut filter uses the very latest coating technology to deliver the finest filtration quality, and lifetime durability.

The Baader Planetarium UV-IR-Cut Filter features true optical quality glass substrate and coatings. Why spend all your money on quality primary optic, only to place a lower grade filter optic in the path? It features:
- Unmatched 98% Average Transmission! Freedom from ghost images (very low reflection multi-coating, Striae-free, and plane-parallel substrate).
- Extremely Sharp Cutoff at 690nm (leaves all the visible red, including the important 656nm H-alpha emission line).
- Sharp cutoff below 400nm. Eliminates violet halos around bright stars (more effectively than simpler so-called Minus Violet photographic filters).
- Combine with any of the other Baader filters to deliver the sharpest images possible.
