Abstract

A device for measuring the performance of an optical detector includes a cryostat, a holder capable of receiving the detector, secured to the inside of the cryostat, and means for measuring the performance of the detector. It also includes a screen arranged around the holder capable of limiting the radiation likely to reach the holder in a wavelength range of the detector, and a single-mode optical fiber in the wavelength range of the detector, inserted in an opening of the cryostat. The device further comprises at least one luminous flux generation module that incorporates a fibered source capable of generating the luminous flux in the optical fiber.
