49mm X-Series IR720 Infrared Filter for Camera Lens. Our IR720 infrared filter eliminates visible light below 720nm and passes infrared light to the sensor. Produces great special effects. These filters are not coated. What are infrared filters? In contrast to the naming convention of optical filters where the name of the filter denotes the wavelengths that are blocked, photographic filters are named for the color of light they pass. Thus a blue filter makes the picture look blue. A black filter marginally allows more light in the blue wavelength to pass resulting in a slight shift of the color temperature of the photo to a cooler color. Because of this, the term IR filters is commonly used to refer to filters that pass infrared light while completely blocking other wavelengths. Unlike the eye, sensors based on silicon including CCDs and CMOs sensors have sensitivities extending into the near infrared. Such sensors may extend to 1000 nm. Digital cameras are usually equipped with IR-blocking filters to prevent unnatural-looking images. IR transmitting (passing) filters, or removal of factory IR-blocking filters, are commonly used in infrared photography to pass infrared light and block visible and ultraviolet light. Such filters appear black to the eye, but are transparent when viewed with an IR sensitive device. What does an infrared filter do? Our infrared filter blocks UV and Visible light in the spectrum up to 720nm. While appearing black to the eye, they transmit infrared light. When taking shooting with an infrared filter, interesting effects can be achieved, since infrared is actually heat. Objects that are alive and transmit or reflect heat will appear to be bright. This made infrared photography invaluable in discerning living objects from painted camouflage, for example. Today infrared photography opens up a whole new way of looking at the world from conventional visible light. Sizes Available: 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm
