<p>Disclosed is a back focus adjusting system for an infrared camera including a lens unit having a lens group to be mounted on the camera main body. The camera main body includes an infrared detector disposed in a vacuum chamber and has a detecting surface that detects the infrared rays; a memory means that stores a position information on the detecting surface obtained by measuring a position in an optical axis direction of the detecting surface of the infrared detector; and a transmitting means that transmits the position information on the detecting surface to the lens unit. The lens unit includes a receiving means that receives the position information on the detecting surface transmitted from the transmitting means of the camera main body and focal position adjusting means that adjusts a position in the optical axis direction of the lens group.</p> |
