Abstract

The present invention relates to the device for spectral half-width narrowing and exact wavelength selection for the LED chromatography detector, wherein the concave mirror (1) is located behind the LED (3) and behind the slits (2), in front of which there are the diffraction grating (9) and the focusing slit (4), behind which there is the beam splitter (5) to reflect the beam to the reference diode (8) and, through a cuvette (6), to the measuring diode (7).
