spectrometer in the image to two channels for the detection with a wide band of frequencies of the spectra of the images provided by a telescope

摘要

the spectrometer is jointly connected to a telescope (101), such as, for example, in an apparatus mounted on aircraft or satellites to readings spettrometriche soilit includes two optical slits placed in the focal plane (f, f) of the telescope (101) and invested by the beam (b) of radiation focused by the telescope (101); the optical slits are ricin an optical system avate separator channels (115) of small size compared to the diameter of the optical system of collimation (109) and place on the focal plane (f, f) of the telescope (101).the intersection of the optical axis (t) of the same with the optical axis (c) of the collimation system (109) (fig. 1).
