Foto4easy 43mm Infared Filter,Adjustable 530nm to 750nm Infrared X-Ray IR Filter for DSLR Camera Lens

• 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.
• Six-IN-One DESIGN: 43mm Six-IN-One adjustable infrared filter, you don't have to carry a bunch of filters for shooting. Just one filter, free to use in 530nm to 750nm light.
• This 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 whichever wavelengths you are using.
• 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.
