Product highlights and buying context
The 37mm, 665nm Infrared Lens Filter Pro from Kolari Vision is a circular filter with 37mm threading on both sides. This pro edition features multicoated glass in a brass ring with knurled edges. This 665nm version requires a full spectrum modification to be made to your camera in order to function properly. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, this 665nm filter will work as intended to block visible light up to 665nm from the light spectrum. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)
A full spectrum modification is required to be made to your camera.
