    Abstract: An optical device may include a narrowband optical filter to receive a beam of light at a selected angle of incidence, wherein the beam of light is caused to be received by the narrowband optical filter at the selected angle of incidence by a steering element included in the optical device, and output a filtered beam of light associated with the beam of light, wherein a wavelength of the filtered beam of light depends on the selected angle of incidence of the beam of light on the narrowband optical filter. The optical device may include a photodiode to receive at least a portion of the filtered beam of light after the filtered beam of light is outputted by the narrowband optical filter.

    Abstract: A spectroscopic assembly may include a spectrometer. The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe to transfer the light reflected from the sample. The light pipe may include a first opening to receive the spectrometer. The light pipe may include a second opening to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.

    Abstract: A sensor device may determine a first optical sensor value associated with a first displacement and a second optical sensor value associated with a second displacement, wherein the first displacement is between an emitter associated with the first optical sensor value and a sensing location used to determine the first optical sensor value, wherein the second displacement is between an emitter associated with the second optical sensor value and a sensing location used to determine the second optical sensor value, and wherein the first displacement is different from the second displacement. The sensor device may determine one or more measurements using the first optical sensor value and the second optical sensor value, wherein the one or more measurements relate to a first penetration depth associated with the first optical sensor value, and a second penetration depth associated with the second optical sensor value.
