ABSTRACT:
A radiometric standard detector responsive to infrared energy comprises an indium antimonide photovoltaic generator, a first mirror and a vacuum dewar including a cold finger and a window. The first mirror and photovoltaic generator are positioned in the dewar to form an optical energy trap. The generator is on the cold finger. A second mirror is external to the dewar. The window, both mirrors and the generator are positioned so a beam of the infrared energy is incident on the window and a portion of the infrared energy incident on the window is reflected from the window to the second mirror, then back to the window.
