Abstract: A modular housing for a spectrometer, the housing comprising at least two modules, the housing further comprising: a sensor recess configured to receive a sensor, the sensor being configured for determining at least one light spectrum characteristic of light received after optical interaction of the light with a sample; an aperture configured for receiving and guiding the light received after the optical interaction along a reception path extending from an entrance of the aperture to the sensor recess; and at least two channels configured for guiding and emitting light out of the modular housing, such that the light, after the optical interaction with the sample, is received at the entrance of the aperture; wherein the at least two channels are arranged along intersecting or skew axes; and wherein at least two of the at least two modules comprise respective ones of the at least two channels.

Abstract: A multi-pixel spectroscopy sensor for spectral analysis of a sample under test including an array of pixel elements generating a dataset including a plurality of data values corresponding to the pixel elements upon illumination of the sample by a light source. Each of the pixel elements including a stack of layers including first and second reflective structures, a phase tuning element, a detector element, and contact elements. The sensor further includes a read-out circuit connected to each of the contact elements for simultaneous read-out of a plurality of photocurrents for generating and outputting the dataset for the spectral analysis of the sample under test. The phase tuning element of each of the pixel elements is configured for a different wavelength response of the light and each photodetector of the pixel elements is comprised of a semiconductor material.
