Abstract
(EN)
Spectrometer systems are provided including a detector array (320); an imaging lens assembly (327) coupled to the detector array, the imaging lens assembly including a first element of positive optical power (336) followed by a second element of negative optical power (333) and a positive optical power element (325) split into two opposing identical singlets; a dispersive element (345) coupled to the imaging lens assembly; and a fixed focus collimator (353) assembly coupled to the dispersive element.
