BP485 is commonly used as an internal infrared blocking filter in cameras. When working with any camera that has had its internal filter removed, a mounted BP485 filter can also be considered in order to, when desired, allow it to once again work like the unmodified camera. BP485 is A/R coated on both sides and its spectral response in the blue portion of the spectrum is excellent compared to other absorptive IR blocking filters.

MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.
