Abstract
The present disclosure concerns a monolithic spectrometer for spectrally resolving light. The spectrometer comprises a body of solid material having optical surfaces arranged to guide the light along an optical path inside the body. A collimating surface and focusing surface are part of a single surface having a continuous optically functional shape. The surfaces of the body are arranged to have a third or fourth part of the optical path between a grating surface and an exit surface cross with a first part of the optical path between an entry surface and a collimating surface.
