The Yukon 100mW infrared illuminator is a powerful infrared torch emitting light at the lower end of the red/infrared spectrum. The light emitted is very intense, but undetectable by the human eye. The 200m range of the 100mW infrared illuminator is combined with a weaver mount and will help to double or even triple the viewing distance of the Yukon NVMT 4 Generation 1+ monocular by supplying a light spot at range.
