Infrared filter for flashlights with 1.62" diameter bezel

The F39 slip-on infrared filter cancels out the non-infrared portion of the light spectrum to produce a smooth beam of infrared light for use with night vision devices and infrared-capable video cameras. For military or law enforcement infrared applications, SureFire also recommends the M1 Illuminator, as its dedicated infrared design may be more appropriate for mission critical tasking. The spring-loaded cover flips open with slight thumb pressure, and is held open by spring tension until manual pressure is applied to re-close the cover.

Features:

-Fits 1.62" bezels, including 9AN
-Spring loaded cover flips open quickly when white light is needed
-Provides secondary protection to flashlight lens window
-Slips over bezel
