FocusFoto FOTGA 67mm All-in-One Adjustable Infrared IR Pass X-Ray Lens IR Filter, Variable from 530nm to 650nm 680nm 720nm 750nm Optical Glass

  • 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..
  • Digital cameras are usually equipped with IR-blocking filters to prevent unnatural-looking images. IR-transmitting (passing) filters, or removal of factory IR-blocking filters, are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light. Such filters appear black to the eye, but are transparent when viewed with an IR sensitive device..
  • The creative adjustable IR filter is a compact all-in-one variable wavelengths filter that adjusts the amount of wavelengths with just the twist of your wrist. The index marks on the filter let you know exactly the amount of wavelengths at a glance. Giving you clear and precise shots at....
