Infrared and Ultraviolet LEDs
Infrared (IR) and Ultraviolet (UV) LED Information
Imagine being able to see in total darkness. It is easy with a standard CCD video camera and our IR (infrared) illuminators. Most CCD cameras, as well as night vision scopes, are sensitive to IR light. If you illuminate objects with IR, the camera will see as though being lit by a floodlight. It will look completely dark to the unaided human eye.
There's nothing magic about this board. It's a circular array using 48 high-intensity IR LED's and appropriate drive circuitry. The real magic is your CCD video camera. CCD sensors are sensitive to IR light that you can't see. The IR illuminator lights the scene with infrared light and the camera sees in low-light conditions. The small size allows easy hiding in clocks, smoke detectors, pictures or any object you can think of. Place a piece of smoked plexiglass in front (it looks clear to IR) and you’ve hidden your IR light source. The whole array will illuminate like what you'd expect of a bright flashlight. The IR light generated from this panel is completely invisible to the human eye. There is no red glow indicating the panel is on. Great for covert surveillance applications.
IR illuminators are available in two frequencies depending on your camera/sensor requirements. 940nm which have no glow and 850nm which have a slight red glow. Boards accept DC voltage from 12v to 14v and contain high-quality ultra-bright IR LEDs.
UV displays have many purposes. These include bank note counting and counterfeit detection (bills, credit cards, documents, etc.), fluorescence disclosing and verification, locating UV sensitive creatures such as scorpions, sterilization, pesticide, black lights, stamp collecting, industrial curing and used in printed circuit board photo etching.
UV LEDs have the same long life expectancy as standard LEDs. They should last well over 10,000 hours (27 years) of constant use.
Warnings and Handling Instructions
UV-LEDs emit invisible ultraviolet radiation when in operation. They may be harmful to eyes or skin, even for brief periods. Do NOT look into the UV-LED during operation. Be sure that you and all persons in the vicinity wear adequate UV Safety protection for eyes and skin. If you incorporate a UV-LED into a product, be sure to provide WARNING labels.
