Baader 50.4mm Unmounted Round UV/IR Cut / L-Filter: The Baader UV-IR Cut/L Filter is a must for all digital imaging with DSLR cameras, CCD cameras, and modified webcams. It removes the unwanted UV and IR wavelengths from your images by blocking UV below 400 nm and IR above 680 nm. The Baader UV-IR Cut filter is also useful for protecting valuable H-Alpha filters from heat stress and damaging IR (Daystar, etc). This model is 50.4 mm in diameter, 3 mm thick, and unmounted.

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.

Features: Baader 50.4mm Unmounted Round UV/IR Cut / L-Filter

Unmatched 98% average transmission

Freedom from ghost images; very low reflection multi-coating, striae-free, and plane-parallel substrate

Extremely sharp cutoff at 690 nm but leaves all the visible red, including the important 656 nm H-alpha emission line

Sharp cutoff below 400 nm

Eliminates violet halos around bright stars, more effectively than simpler Minus Violet photographic filters

True optical quality glass substrate and coatings; don't spend all your money on quality telescope optics, only to place a lower grade filter in the light path

Combine with any of the Baader filters to deliver the sharpest images possible

This Baader UV-IR Cut/Luminance Filter is 50.4 mm in diameter and unmounted for placement in appropriately sized filter wheels.
