Offner spectrometer design
WebbModern and powerful mirror optics for imaging, spectroscopy and beam shaping are based on complex optical surfaces. In the aerospace field, Fraunhofer IOF investigates the design, manufacture and assembly of modern telescope and spectrometer optics with on-axis and off-axis aspheres, free-form surfaces and structured surfaces (gratings). Webb1 feb. 2024 · We propose a method for calculating the point scattering function (PSF) of an Offner imaging hyperspectrometer with a diffraction grating in the approximation of scalar diffraction theory. The method consistently takes into account limitations and diffraction of a light beam by elements of the hyperspectrometer system in accordance with the …
