Fotga 46mm 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 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 You don't have to carry a bunch of filters for shooting. Just one filter, gives you from the range 530nm to 750nm freely International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
