485nm Absorptive Visible Bandpass/Near-IR Block Filter

Bandpass Filter

Description:

485nm 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 485nm filter can also be considered in order to, when desired, allow it to once again work like the unmodified camera. 485nm 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.
