Designed to block nearly all visible light, this 62mm I-Ray 690 Infrared Filter from Singh-Ray is well-suited for those looking to get into infrared photography. It is made of optical glass with a slim aluminum frame that is anodized for durability. The thin profile helps avoid vignetting on wide-angle lenses for simplified use.
The filter works by blocking electromagnetic radiation with a wavelength shorter than 690nm, which includes most but not all visible light. This results in near-infrared images with an interesting off-color look, while still allowing for traditional black and white IR pictures. Most importantly, this range is designed to permit digital sensors to capture infrared pictures, even those still equipped with their cut-off filters. As such, they are ideal for beginners that do not have dedicated cameras or infrared film.
