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

Kolari UV/IR Cut H-Alpha Pass Filter

Block unwanted UV and IR light while allowing H-Alpha wavelengths to pass, perfect for capturing stunning celestial details in astrophotography.

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.

Wide Angle Color Shift: When using this filter with a full-spectrum camera and wide-angle lenses, you will experience a purple color shift in the left and right portions of your images. The color shift is most prominent at focal ranges 24mm and under.

FAQs

The UV/IR Cut H-Alpha Pass Filter blocks unwanted ultraviolet (UV) and infrared (IR) light while allowing H-alpha wavelengths to pass through, making it ideal for both astrophotography and achieving accurate color representation.

For full-spectrum cameras, this filter enhances astrophotography by allowing the H-alpha band to come through, capturing deep sky objects with greater detail. For stock digital cameras, it blocks unwanted UV and IR light contamination, resulting in more true-to-life colors, which is especially beneficial for cinema cameras and digital cameras with weaker IR blocking filters.

Yes, it can be used with both full-spectrum and stock digital cameras, providing benefits tailored to each type of camera.

The filter allows H-alpha light to pass through without loss of light, so standard exposure settings can typically be used.

Clean the filter gently with a soft, lint-free cloth and lens cleaning solution. Avoid using harsh chemicals or abrasive materials to maintain its optical quality.
