Abstract
A spectrometer is provided including a camera and an axial symmetric camera mount configured to receive the camera and to rotate. The spectrometer furthers include an input for providing optical radiation to a spectrometer system; a diffraction grating for dispersing the optical radiation along a prescribed plane; at least one lens for focusing wavelength-dispersed light onto at least one array of a detector of optical radiation, wherein the camera has at least one linear array of elements for detecting optical radiation; a mechanical housing, wherein the axial symmetric camera mount is configured to couple the camera to the mechanical housing; and a means for rotating the camera coupled to the mechanical housing about an axis. Related systems and methods are also provided.
