This UV/IR Cut off filter blocks undesirable ultraviolet and infrared rays that may interfere with obtaining the high contrast and quality images possible with a digital sensor
It serves as a permanent lens protector;digital imaging with DSLR cameras;CCD cameras;and modified WebCams;or telescope
Correct chromatic aberration; SV231 telescope filter prevents unwanted color banding in the blue spectral range; minimizes blue wavelengths in out-of-focus areas
OD>4; the higher the filter cut-off depth; the smaller the noise and the higher the imaging contrast
AR anti-reflection coating design; transmittance exceeds 95%; improves the contrast and clarity of fast achromatic telescopes; ensures image quality and brightness; obtains more observable light
