Feature:1. High quality aluminum alloy frame design, the front of the frame with thread which can be mounted lens cover and other accessories at any time.2. IR passing filters are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light.3. The rotating outer ring of the filter can adjust the wavelength arbitrarily, which can be changed from 530nm to 750nm.4. Widely 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.5. Convenient and portable, you don\u0027t have to carry a bunch of filters for shooting. Just one filter, gives you from the range 530nm to 750nm freely.Specification:Features:High quality aluminum alloy frame design, the front of the frame with thread which can be mounted lens cover and other accessories at any time.
