Designed for flood mode applications, the Collimating Lens uses plano convex lens technology to redirect unused spill light back into the searchlight's beam. This results in an evenly illuminated field of view at wide beam angles greater than 20Adeg. The Collimating Lens features an integrated stacking filter adapter, meaning that other Maxa Beam filters may be "stacked" in front of it for combined use. This lens attaches to the searchlight using a positive locking technique that requires no threading or tools, making it easy to install or remove in seconds with only a quarter turn.
