This bandpass filter blocks all light wavelengths except blue. It is ideal for blocking ambient lighting and improving contrast when combined with blue (470 nm) LED lights. It is also a necessary component for many UV-excited blue fluorescence (430-500nm) imaging applications.
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.
