Fotga 77mm Optical Circular Adjustable Infrared Filter IR Pass Filter X-Ray Filter Variable From 530nm to 750nm Six-in-One Lens Filter for Infrared Photography

Infrared filters, sometimes as IR filters or heat protection filters are designed to allow IR medium infrared wavelengths while blocking visible light. They are often used in devices with bright bulbs (such as slide and overhead projectors) to prevent unexpected heating. There are also filters that are used in fixed condition (CCD or CMOS) video cameras due to the high sensitivity of the camera, many sensors near infrared light are possible to IR These filters typically have a blue colour as they sometimes block some of the light from the shorter visible light and UV wavelengths. Digital cameras are usually equipped with IR cut filters to prevent unnatural looking images. IR transmitting (passing) filters, or removal of the factory IR blocking filters, are commonly used in infrared photography to pass through infrared light and block visible and ultraviolet light. These filters appear black around the eye, but are transparent when viewed with an IR sensitive device. The creative adjustable IR filter is a compact all-in-one variable wavelength filter that adjusts the amount of wavelengths, with exactly the torsion of your wrist. The index markings on the filter allow you to know exactly the amount of wavelengths at a glance. Give clear and precise shoes at each wavelength you use. It offers you the freedom to create different wavelengths freely. You don't have to carry out a range of filters for shooting. Just one filter, releases you from the range of 530nm to 750nm.
