Spectrometry systems with decreased light path

A spectrometer comprising:

• a diffuser;
• a detector comprising a plurality of regions, each region of said plurality of regions comprising multiple sensors;
• a lens array comprising a plurality of lenses, each lens of the lens array corresponding to a region of said plurality of regions;
• a filter array corresponding to the lens array, the filter array comprising a plurality of filters, wherein each filter of the plurality of filters is configured to transmit a range of wavelengths different from other filters of the plurality, wherein the diffuser comprises a cosine diffuser to generate a Lambertian light distribution;
• and
• a support extending between the detector and the lens array, wherein the support is shaped and sized to support the lens array and position the lens array at a focal length from the detector, wherein the support comprises a plurality of channels configured to pass light from the plurality of lenses of the array to the plurality of regions of the detector.
