SP705 Near-IR/Deep Red Absorptive Block Shortpass Filter
Near-IR/Deep Red Absorptive Block Shortpass Filter for machine-vision imaging — passes 370-630nm and blocks out-of-band light for repeatable contrast on the line.
Overview [ 01 ]
SP705 is an absorptive infrared rejection filter recommended for blocking stray or scattered light from higher power near IR light sources, particularly lasers, and protecting a camera's sensor. Both surfaces are multilayer anti-reflection coated to improve visible light transmission and prevent staining.
