Attach an infrared filter to a Maxa Beam to turn the searchlight into a covert IR illuminator.  The Maxa Beam’s infrared beam is invisible to the naked eye but will aid IR-sensitive cameras and night vision devices at long ranges.

Choose from four longpass filter options that block light energy below 715nm, 850nm, 900nm and 950nm. The 850nm filter’s combination of range and covertness make it the most popular choice for most applications.

Each filter attaches to the searchlight using a positive locking technique that requires no threading or tools, making it easy to install or remove a filter in seconds with only a quarter turn.
