An excellent filter that cuts the infrared spectrum in the spectrum of light and ultraviolet. The filter has a 2 "filter thread on both sides of the luminaire, thanks to which it can be combined with other filters in this standard.The filter surfaces meet strict quality tolerances, while dielectric coatings guarantee scratch resistance and durability filter characteristics over time.
When combined with a red filter, the IR Cut filter can raise the contrast of the CCD chip by 500%, thus enabling excellent images of the H-II area.
CCD and CMOS chips are sensitive in the UV and IR areas (ultraviolet and infrared), while lenses for telescope lenses are not well corrected outside the visible spectrum, therefore the contrast of images without an IR filter can be lowered.
Fixing: through filter thread
