DISPLAYING FOCAL SPECTROMETRE (VERSIONS) Russian patent published in 2010 - IPC G01J3/12 

FIELD: physics.

SUBSTANCE: spectrometre has on a single optical axis an input lens (1), a focusing and diverging lens (4), two identical fibre-optic converters, a lens (8) of a matrix reception device (9) with a data processing unit (10). Each fibre-optic converter has smaller (2 and 7) and larger (3 and 6) faces. The converters are made from identical fibres which are transparent in the operating spectral range of the spectrometre. An opaque screen (5) covers the centre of the lens (4).

EFFECT: possibility of detecting fast processes when controlling the aperture ratio and spectral resolution of the spectrometre.
