The Kase Infrared 720NM Magn 77mm is a specialized camera filter designed for infrared photography applications. This 77mm diameter filter blocks visible light while allowing infrared radiation at 720 nanometers to pass through, enabling creative photographic effects and scientific imaging. Made from precision optical glass, the filter maintains image quality with consistent infrared transmission properties. The 77mm thread ensures a secure fit on compatible lenses, while the standard black finish minimizes light reflections. This filter is suitable for landscape photography, architectural documentation, and technical imaging processes where infrared sensitivity is required. The infrared transmission properties allow photographers to capture unique tonal reproductions and contrast patterns that are not visible to the naked eye. Exposure correction is typically necessary, as infrared filters significantly reduce visible light transmission. The filter is compatible with all camera systems that use 77mm threaded lenses and requires no additional mounting hardware. Care should be taken during handling and storage to protect the optical surfaces from scratches and fingerprints. For optimal results, use cameras with good infrared sensitivity or consider converting a camera for dedicated infrared photography. The filter construction includes multi-coated surfaces to reduce internal reflections and preserve optical clarity. When not in use, store the filter in a protective case to prevent damage to the precision glass surfaces. This professional accessory is designed for photographers looking to expand their creative possibilities through infrared imaging techniques.
