Optical System of SHARP I

The image shows the optical system of Speckle-Camera SHARP I, located inside the golden cryostat.

Light gets into the cryostat through the tiny window, on the left in the image, and it’s reflected by four small prisms before arriving to the detector array, on the right in the image.

Temperature inside the cryostat is kept down to 77 K, that of liquid nitrogen.
