Abstract
There is provided an infrared signal receiver which includes a photo-detector unit receiving light in a predetermined infrared wavelength region, sent from a remote operating unit; and an optical element disposed in front of the photo-detector unit, allowing the light of the predetermined infrared wavelength region to transmit therethrough in preference to other infrared wavelength region. In the receiver, the predetermined signal wavelength region is a region of 930 nm or longer and 960 nm or shorter, and mean transmittance of light of the optical element in the predetermined signal wavelength region is larger than mean transmittance of light in a region of 900 nm or longer and shorter than 930 nm, and/or, mean transmittance of light in a region of longer than 960 nm and 1,020 nm or shorter.
