The 665nm 4 x 5.65" Cine Infrared Pro Filter from Kolari Vision is a multicoated glass filter for compatible matte boxes. It blocks visible light up to 665nm from the light spectrum. 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, the filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)
Note:
A full spectrum modification is required to be made to your camera.
