The multispectral binocular from Pard is compatible with 940 nm and 850 nm infrared illuminators. If it was purchased with a 940 nm illuminator, it can be quickly swapped for this 850 nm interchangeable illuminator, original from Pard, when needed. The 850 nm version has a longer range, but the light from the IR illuminator is noticeable. Ideally, you have both wavelengths available.
