This light-balancing filter attenuates blue light from typcal white LED and metal halide light sources. It delivers a more natural, balanced image, and is especially useful with color cameras. This filter passes wavelenths greater than 500 nm, absorbs UV and blue 200 — 500 nm, and attenuates 400 — 500 nm wavelenths.
This mounted filter screws in to the threads on the front of a matching lens. The filter coating is durable and non-hydroscopic. It withstands cleaning, heat, humidity and vibration.
Mounted filters screw into the threads on the front of a matching lens. Configure to select the appropriate thread. Unmounted filters and slip-mount filters are available on request.
