Features: High quality aluminum alloy frame design, with threaded front to allow mounting of lens caps and accessories. IR pass filters are commonly used in infrared photography to transmit infrared light while blocking visible and ultraviolet light. The rotating outer ring allows adjustable wavelength control from 530nm to 750nm. Suitable for use with solid-state (CCD or CMOS) video cameras, taking advantage of the high sensitivity of many camera sensors to near-infrared light. Compact and convenient design eliminates the need to carry multiple filters; one filter provides continuous coverage from 530nm to 750nm. Specifications: Brand: Fotga Material: Aluminum Alloy + Optical Glass Wavelength Range: 530nm - 750nm Filter Size: 62mm / 67mm / 72mm / 77mm / 82mm (optional) Package List: 1 x Infrared Filter 1 x Storage Box
