#CFD36B SP705 Near-IR/Deep Red Absorptive Block Shortpass Filter

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.

The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter's capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance. Filters 62mm and greater have a surface quality tolerance of 60/40.
