Heliopan 48mm IR RG 715 (88A) Filter

Item Includes Heliopan RG 715 Infrared Filter Manufacturer Warranty Overview The Heliopan RG 715 Infrared Filter is a specialized optical pass filter designed for experimental black-and-white, color false-color, and scientific infrared photography. By completely blocking the visible light spectrum up to 715nm, it isolates the invisible near-infrared spectrum to capture striking imagery where foliage glows white and skies turn dark. This optical glass matches the behavior of classic Kodak Wratten 88A and Hoya R72 filters, acting as a gateway to utilize the residual infrared sensitivity found on various digital and video sensors. Built with premium Schott glass and a low-profile brass mounting ring, it delivers maximum sharpness while preventing vignetting on wide-angle setups. Features Deep Spectrum Isolation: Absorbs all visible light below 715nm to transmit only invisible near-infrared radiation. Experimental Tonal Shift: Enables wood effect foliage whitening and deep contrast separation for fine-art monochrome and false-color layouts. High-Grade Schott Optics: Employs ground and polished Schott glass substrates to preserve pixel-level resolution and structural durability. Slimline Brass Housing: Compact brass ring avoids edge shading on wide focal lengths while resisting binding and cross-threading. Digital Sensor Compatibility: Capitalizes on the residual infrared transmission of digital sensors that bypass internal factory cut filters. Double-Thread Design: Retains a front thread of the same diameter to allow compounding with accessories or standard lens caps.
