Detector for spectrometry system

A spectrometer, comprising:

• optics configured to receive input light and generate output light having an arcuate optical pattern;
• and
• a detector configured to receive the output light having the arcuate optical pattern, the detector comprising a plurality of arcuate photo sensor elements,
• each arcuate photo sensor element of the plurality of arcuate photo sensor elements comprising a radial thickness, wherein a first radial thickness of a first arcuate photo sensor element of the plurality of arcuate sensor elements is larger than a second radial thickness of a second arcuate photo sensor element of the plurality of arcuate sensor elements, wherein the first arcuate sensor element is closer to a common center of the plurality of arcuate photo sensor elements than is the second arcuate sensor element.

A method of measuring spectra of input light, the method comprising:

• providing a spectrometer comprising optics and a detector, the detector comprising a plurality of arcuate photo sensor elements shaped to correspond to an arcuate optical pattern of the input light transmitted through the optics;
• measuring an amount of light incident on each of the plurality of arcuate photo sensor elements;
• and
• determining the spectra of the input light based on measurement data generated by the plurality of arcuate photo sensor elements,
• each arcuate photo sensor element of the plurality of arcuate photo sensor elements comprising a radial thickness, wherein a first radial thickness of a first arcuate photo sensor element of the plurality of arcuate sensor elements is larger than a second radial thickness of a second arcuate photo sensor element of the plurality of arcuate sensor elements, wherein the first arcuate sensor element is closer to a common center of the plurality of arcuate photo sensor elements than is the second arcuate sensor element.
