1.Product Description:
Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow IR mid-infrared wavelengths while block visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating. There are also filters which are used in solid state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the shorter visible light and UV wavelengths. In which ways the infrared filter will be used? 1.Archaeology,Military,Police,Medical science,and detective work. Infrared filter allow normally invisible stains and modified items visible. 2.Plant vegetation & Landscape photography. It looks dramatically different when photographed in Infrared. 3.Photographic special effects. Infrared filters give the still and video photographer expressive and unusual effects. In what suitable light source should I use the infrared filters? 720nm for indoor and weak light use, for ordinary DC/DV/DSLR cameras. 760nm for cloudy outdoor at nightfall and brightness indoor.
