Varifocal Illuminator (NuOptic)

Author: Brian Rhodes, Published on Sep 06, 2012

While surveillance users are accustomed to picking varifocal lens for cameras and easily adjusting the FoV on the spot, this is not the case for IR and white light illuminators. Most illuminators require picking the angle before you order (10, 30, 60, etc.), sticking you with whatever the unit delivers even if it is too narrow and leaves dark spots or too wide and fails to cover the far side of the scene. Now, a new US manufacturer named NuOptic is releasing the "Varifocal Illumination System" or VIS. Inside, we examine its features, pricing and competitive positioning versus Raytec.

Key Feature: Beam Adjustability
