Zeiss Concave Grating 000000-1329-190
Description
Concave diffraction gratings are diffractive optics components for compact spectrometers. By combining dispersive and imaging properties in a single element concave gratings reduce stray light, increase light intensity, and are ideal for imaging the spectrum on a diode array or a CCD/CMOS sensor. The basic form of all imaging gratings is the Rowland circle grating.
ZEISS concave gratings are produced holographically. This optimizes the focal plane and minimizes aberrations such as astigmatism, spherical aberration and coma over a wide spectral range with a range of groove profiles.

Frequently Asked Questions
Concave diffraction gratings are diffractive optics components for compact spectrometers.
By combining dispersive and imaging properties in a single element, concave gratings reduce stray light, increase light intensity, and are ideal for imaging the spectrum on a diode array or a CCD/CMOS sensor.
Zeiss concave gratings are used in spectrographs and spectrometers for scientific and industrial applications.
The groove density of the grating is 844.75 ± 0.75 l/mm.
The diffraction efficiency of the grating is ≥ 70% at 210 nm and ≥ 30% at 415 nm for unpolarized light at a constant angle of deviation (cAD) of 4°.
