Abstract
A spectrometer is disclosed. The spectrometer includes a fiber input, a collimator lens, a rotating shaft, a grating, a focal lens and a focal plane which have arranged in order. A broadband incident light of the fiber input becomes a first parallel beam through the collimator lens and separated by the grating into multiple parallel beams of different wavelengths and then focused by the focal lens to emit an output beams to an imaging position on the focal plane. The spectrometer can rotate the collimator lens and fiber input to change the imaging position on the focal plane.
Claims10
A spectrometer, comprising:
- a fiber input, a collimator lens, a rotating shaft, a grating, a focal lens and a focal plane which have arranged in order, a broadband incident light of the fiber input becoming a first parallel beam through the collimator lens and being separated by the grating into multiple parallel beams of different wavelengths and then being focused by the focal lens to emit an output beams to an imaging position on the focal plane;
- wherein when the collimator lens and the fiber input rotate to change the imaging position on the focal plane, a moving direction of the fiber input and a moving direction of the imaging position on the focal plane are opposite to each other.
A spectrometer, comprising:
- a fiber input, a relay lens, a collimator lens, a grating, a focal lens and a focal plane which have arranged in order, a broadband incident light of the fiber input being extended by the relay lens and then becoming a first parallel beam through the collimator lens and being separated by the grating into multiple parallel beams of different wavelengths and then being focused by the focal lens to emit an output beams to an imaging position on the focal plane;
- wherein when the relay lens and the fiber input move to change the imaging position on the focal plane, a moving direction of the relay lens and the fiber input and a moving direction of the imaging position on the focal plane are opposite to each other.
