Protecting Your Viewfinder

Have you ever seen what magnified sunlight can do to an insect? Similar damage can occur to your infrared camera if you are not careful.

Many infrared imagers utilize monocular eyepieces as monitor screens. When working outdoors, the LCD monitor display can be severly damaged or destroyed if sunlight enters the viewfinder through the magnifying lens of the viewer assembly. If the sunlight is strong enough and at the appropriate angle, the focused solar energy can melt a hole in the LCD screen in just a few seconds.

Always protect your eyepiece by shading or covering it when working outdoors to avoid allowing sunlight to enter the viewfinder. Doing so may prevent you from having to replace a costly eyepiece.
