These filter sheets are for use on your own torch or lamp. Cut to cover the torch lens they will create infrared light which is visible only to a night vision device or infrared camera. Providing an additional source of infrared light can be useful when using night vision equipment and can vastly improve the viewing distance of Generation one or two scopes (with c. 830nm output).
Filter sheets are made of a tough and rigid material, but can be cut to fit most torches and lamps using a suitable tool.
Available as 3mm thick or 5mm thick sheets and in squares of 10cm or 20cm.
