The Heliopan 40.5mm IR RG 665 Filter is used for infrared photography with digital cameras and specialized infrared film. This nearly opaque filter blocks all visible light up to 665nm, enabling recording of subject matter and scenes that are not visible under normal conditions. Due to the nature of infrared photography, the filter factor for this filter is highly variable and depends largely on the ISO sensitivity in use and lighting conditions.
