BP485-52 | BP485 Absorptive Visible Bandpass/Near-IR Block Filter

Part: BP485-52

Diameter: M52 x P0.75

The MidOpt BP485-52 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, which, when desired, allows it to 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.
