Imaging hyperspectrometer-consol
Produced imaging hyperspectrometer is used as a consol. Due to minimized design, the spectrometer consists only of a diffraction grating and diaphragm, so it becomes a very inexpensive device. A diffraction grating with a period of 6 µm was made using the technology of direct laser beam recording on chromium.

Modeling of arrangement tolerances for the optical elements in a spaceborne Offner imaging hyperspectrometer [PDF]
We propose mathematical tools and analyze the quality of an image in the detection plane of an Offner imaging hyperspectrometer, evaluating conditional tolerances for the position of the spectrometer elements. The results of modeling of a combined effect

A compact imaging hyperspectrometer
Abstract The paper describes the design of a compact hyperspectrometer equipped with a transmission phase diffraction grating, which is used as a dispersing element. The calculation of the microrelief parameters of the dispersing element is given. The spectral characteristics of the developed device are investigated.

Hyperspectrometer based on a harmonic lens with diffraction grating
We have produced a harmonic lens with a diffraction grating on one surface of the quartz substrate We have made on the basis of such a harmonic lens a compact imaging spectrometer. We conducted experimental studies of the hyperspectrometer. We have confirmed the functionality of the hyperspectrometer as a result of research.

Analytical calculation of diffraction order intensities for a hyperspectrometer
Abstract We employ a geometric optics approach to calculate the eikonal of a light field at the output of a diffraction grating in the immediate microrelief vicinity. Analytic relations to calculate the diffraction order intensities as functions of the grating step height, line spacing, wavelength of incident light, and incidence angle ...

The study of the basic operating parameters of a hyperspectrometer based on the Offner scheme
Abstract In this article, the comparing of mathematical modelling results of a hyperspectrometer based on the Offner’s scheme is considered. This modelling was carried on within geometric optics. The goal of this comparing was a confirmation of mathematical model correctness, which was developed.
