#4fc6de SP635 Absorptive Visible Shortpass/Near-IR Block Filter

SP635 filters are commonly used inside cameras to block infrared light. When working with any camera that has been modified and its internal IR cut filter has been removed, a SP635 filter mounted on the front of the lens, when desired, can return function once again like the unmodified camera. This is an absorptive infrared rejection filter that is also recommended for protecting a camera’s sensor from stray light emitted by lasers or other high power near-IR light sources. SP635 filters are A/R coated on both sides to maximize visible band transmission while offering superior out-of-band blocking.
