Offner gratings For imaging spectrometers
Offner gratings are used in applications with spatially resolved spectral information, especially hyperspectral imaging. Holographic fabrication reduces stray light and increases image quality. In the holographic process at ZEISS, the blaze profile is applied during holography best suited to the shape of the optical substrate. ZEISS has the in-house expertise to design and make customized Offner gratings.
