Gratings
ZEISS offers mechanically
ruled plane gratings as well as holographically produced plane
and concave gratings at the highest quality level. The standard program includes the production of precision replicas and specially manufactured master gratings.
A diffraction grating is a periodically structure of subsequent most evenly spaced grating lines. Those grooves or opaque lines diffract the incident light depending on its periocity and microstructure. Depending on the light's incidence angle, rainbow-colored patterns are discernible on a projection surface behind a transmission or reflection grating (except for gratings of the zero order). The colored patterns are known as optical spectrum. This dispersion effect is used in different fields of applications.
The Benefits of Gratings
ZEISS manufactures a wide range of optical diffaction gratings with the conventional ruling technique and interference lithography. The benefits of holographically produced gratings are high diffraction efficiency, even in high groove frequencies and very low stray light in combination with gratings on flat, concave, convex, aspherical and free form substrates. Sinoidal, lamellar and blazed gratings are commonly used. With high detection sensitivity even for low-intensity signals, ZEISS gratings measure very accurately in the visible and infrared ranges.
