Kolari Vision UV/IR Cut Filter (H-Alpha Pass)

Clear

Description

Our all-new Kolari Vision Pro UV/IR Cut Filter (H-Alpha Pass) helps prevent color casts and unwanted IR leaks for CMOS and CCD in situations where the original UV/IR still lets some IR light pass. This filter has a similar transmission to our UV/IR Cut Hot Mirror Filter, but with an expanded spectral response covering the H-alpha and sulfur II emission lines making it also useful for Astrophotography when used with a Full-Spectrum converted camera. When used with a full spectrum converted camera, these filters will provide a greater than 4 fold increase in sensitivity in the H-alpha line compared to a stock camera and a greater than 6 fold increase in sensitivity in the sulfur II line. Our UV/IR Cut (H-Alpha Pass) also filter comes in either our standard or our Pro Gen 3 Brass filters rings.

Perfect for blocking unwanted UV and IR light, this filter can be used as a protective filter as it exhibits no color cast and no exposure correction. Perfect for cameras with a weak IR cut filter, or when using ND filters that do not cut out IR light. Made with Schott B270 optical glass for exceptional clarity and sharpness, this filter is available in either a standard aluminum ring, or our pro brass ring.

Available Now: 55mm Standard, 58mm Standard, 58mm Pro, 62mm Standard, 62mm Pro, 67mm Pro, 72mm Standard, 77mm Standard, 77mm Pro, 82mm Standard, 82mm Pro, 86mm Standard, 95mm Standard

2 reviews for Kolari Vision UV/IR Cut Filter (H-Alpha Pass)

    Well made, high quality filter for your full spectrum camera. I use it both for daytime landscapes, as well as astrophotography. Makes the stars truly shine. Only issue with the brass ring is that the lens hood may not fit.

    Very nice filter. I had previously purchased this filter in a 48mm size to use my FS camera with my scope during astrophotography.
    This filter lets me now use my telephoto lenses also. Well made and gives good color detail.
