Abstract
The disclosure relates to a lens assembly for collimating incoming radiation from an object arranged along an optical axis, comprising: a first lens arranged on the optical axis of the lens assembly; a second lens arranged on the optical axis of the lens assembly; a light filter comprising a non-transparent sheet body with at least one hole; wherein the light filter is arranged: between the first lens and the second lens; in the focal point of the first lens and the second lens; and so that the at least one hole is close to or at the optical axis of the lens assembly. The disclosure further relates to an optical spectrometer for spectrally resolved two-dimensional imaging of an object and a method for spectrally resolved two-dimensional imaging of an object.

An optical spectrometer for spectrally resolved two-dimensional imaging of an object, comprising:
- a lens assembly for collimating incoming radiation from an object arranged along an optical axis, comprising:
- a first lens arranged on the optical axis of the lens assembly;
- a second lens arranged on the optical axis of the lens assembly;
- a light filter comprising a non-transparent sheet body with at least one hole;
- wherein the light filter is arranged:
- between the first lens and the second lens;
- in the focal point of the first lens and the second lens;
- and
- so that the at least one hole is close to or at the optical axis of the lens assembly;
- wherein the optical spectrometer further comprises:
- a dispersing device placed after the lens assembly on the optical axis;
- a multi-lens array arrangement arranged in one plane and arranged to receive the dispersed radiation from the dispersing device;
- and
- a two-dimensional detector arranged to receive the dispersed radiation as directed by the multi-lens array arrangement and located adjacent to the focus of each lens of the multi-lens array arrangement.
A method for snapshot spatially resolved light analysis by an object, comprising the step of,
- dispersing radiation from object by a dispersing device,
- receiving the dispersed radiation from the dispersing device at a multi-lens array arrangement arranged to,
- receiving the dispersed radiation as directed by the multi-lens array arrangement at a two-dimensional detector,
- wherein method further comprises the steps of
- collimating the radiation from object before the radiation reaches the dispersing device by:
- a lens assembly for collimating incoming radiation from an object arranged along an optical axis, comprising:
- a first lens arranged on the optical axis of the lens assembly;
- a second lens arranged on the optical axis of the lens assembly;
- a light filter comprising a non-transparent sheet body with at least one hole;
- wherein the light filter is arranged:
- between the first lens and the second lens;
- in the focal point of the first lens and the second lens;
- and
- so that the at least one hole is close to or at the optical axis of the lens assembly.
