This is the 35.5 mm Infrared and UV Blocking Filter (38) from Heliopan. It cuts UV below 300nm and infrared above 800nm. It is designed for use with black and white and color films that are sensitive to certain values of infrared and UV light not visible to the human eye. Using traditional contrast filters such as a yellow 12, red 25 or green 15 will produce a color shift which may not be desired in the final image. Greens may become blue, red becomes green and yellow becomes blue/green and infrared becomes red.

I have a special internal filter mount in a super telephoto lens. Normal thickness 35.5mm filters will not fit the filter holder slot. Many standard filters are 5mm thick above the screw threads. The Filter holder requires a filter which is no thicker than 4.2mm above the screw threads. How thick are these Heliopan Filters? Slim or Standard.
