Abstract
A spectrometer includes a base, a light input, a light splitter, an image sensor and a shader. The light input is disposed on the base for receiving an optical signal. The light splitter is disposed on the base to split the received optical signal into a plurality of spectral components. The image sensor is disposed on the base, and has a sensing surface for receiving the plurality of spectral components. The shader having a non-ring shape is disposed between the light splitter and the image sensor, and is located on a projection path of a part of the plurality of spectral components. A shadow generated by the shader on the sensing surface falls on an area of the sensing surface corresponding to the part of the plurality of spectral components. A divergence angle of each spectral component out of the part of the plurality of spectral components is reduced.
