Spectrometer player especially for remote exploration

摘要

Spectrometer player to generate a spectrally judder, with a slit (10) to pass light emitted by an object with an optical path for light rays which have passed through the slit in which the optical path has consecutively: a first prism (11, 22) for generating a spectral dissociation of a light beam passing therethrough, wherein the outer surface (11b, 22b) of the first prism located downstream in the optical path is a mercury so that light rays reflected on the outer surface of the first prism and a mercury traverse in a second step the first prism with another spectral dissociation; a minimum of one mirror (12) with a curved outer surface (12a) to reflect a light beam returning from the first prism (11, 22), and at least a second prism (13, 25) in which the light is deflected reflected in the mirror (12) for generating another spectral dissociation of a light beam, wherein the outer surface (13b, 25b) of the second prism located downstream in the optical path is a mercury, so that the light rays are reflected on the outer surface a mercury second prism and pass through in a second step the second prism with another spectral dissociation, until they are focused on an image (16) surface which form a spectrally decomposed image of the slit (10), wherein each prism having two outer surfaces curved and the center of the slit (10), the centers of curvature of the reflective surfaces (12a, 11b, 13b) and the image center slit (16) are essentially situated as over A line.
