Tiffen Infra-Red 87 Filter
Various filters are used to reduce unwanted visible light. Total visible light absorption, transmitting only infrared, can be useful. Suitable for black-and-white infrared film only, the Tiffen infrared 87 filter absorbs unwanted visible light so that more of the infrared is transmitted to the camera. The filter--which is on the dark end of the infrared filter spectrum--fits on cameras with 67mm filter threads.
