What is Infrared (IR) Illuminator and do I really need one?
An Infrared Illuminator or simply IR, is a source of infrared light which is invisible to the human eye. Roughly, it is a flashlight emitting infrared light instead of a visible white/yellow light. It is used to increase available light for brighter images. Most of the IR illuminators on the consumers’ market are based on LED, a Light Emitting Diode, similar to your TV’s remote control. Many of our regular scopes come with an IR to give better performance in dawn and dusk conditions.
Infrared illuminator are the devices used to view in dark areas. IR is not visible to human eyes, so we need special types of glasses to see them. IR can be also seen through the camera. IR is also used for security surveillance. AXTON provides a wide range of IR illuminator and IR lights. http://www.axtontech.com/
