: 82mm 760nm Infrared IR Optical Grade R72 Filter for Camera Lens : Electronics. Lens Material: Germanium Optical Glass 。 Ring Material: Aero Magnalium 。 Filter Effects: Infrared 。 Shape: Circular 。 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. 590nm, 600nm and 630nm for Infrared change machine. The rich colors, custom white balance, the original film in general the sky was bright red, partial brown or amber, plant leaves, blue, sky blue saturation after post-processing, the leaves yellow or golden yellow. 680nm for indoor and weak Shadows use. 720nm for indoor and weak light use. 760nm for cloudy outdoor at nightfall and brightness indoor. 850nm for indoor and weak cloudy outdoor light. 950nm for outdoor and strong light,such as summer time. 1000nm for low latitudes and strong reflective light ,such as on the beach by noon time.
