Albinar 52mm 950nm IR95 Infrared IR Filter

nfrared is a spectrum of light beyond that which we normally see. Infrared photography was only used in film cameras in the past, but despite having an IR blocking filter installed between the lens and the Digital Camera's Sensor, most digital cameras can still react to infrared energy, though at levels far lower than visible light. To take "infrared" pictures - i.e., photos primarily made up of near infrared energy - you need to filter out the visible light and only allow the infrared spectrum through to the lens. The easiest way to do this is to use an infrared filter.
