Abstract
Spectrometer systems are provided including a detector array; an imaging lens assembly coupled to the detector array, the imaging lens assembly including a first element of positive optical power followed by a second element of negative optical power and a positive optical power element split into two opposing identical singlets; a dispersive element coupled to the imaging lens assembly; and a fixed focus collimator assembly coupled to the dispersive element. Related imaging lens assemblies and collimator assemblies are also provided.

A spectrometer system comprising:
- a detector array;
- an imaging lens assembly coupled to the detector array, the imaging lens assembly including a first element of positive optical power followed by a second element of negative optical power and a positive optical power element split into two opposing identical singlets;
- a dispersive element coupled to the imaging lens assembly;
- and
- a fixed focus collimator assembly coupled to the dispersive element, wherein the dispersive element and the fixed focus collimator are integrated together as a rigid piece such that the rigid piece is non-adjustable in all dimensions, wherein the dispersive element is positioned between a positive element of the fixed focus collimator assembly and the first element of positive optical power of the imaging lens assembly, and wherein a fiber of the collimator is fixed and non-adjustable.
