ABOUT GRATING (1)
Mechanically ruled or holographically recorded - our gratings excel in precision and efficiency
Many years of experience in the development and manufacture of diffraction gratings make Carl Zeiss for the right address of diffraction optics. The technical basis of production are holographic exposure systems and ultra-high-precision ruling engines which offer multiple possibilities of modification.
The benefits of holographically produced gratings are their high diffraction efficiency, even with high groove frequencies, and their very low straylight. Holographic procedures also allow the generation of asymmetric and symmetric groove profiles. Mechanically ruled Zeiss gratings distinguish by a particularly uniform groove spacing, resulting in low straylight. This ensures that spectrometers have a high detection sensitivity even for low-intensity signals and provide increased measurement accuracy in the visible and infrared ranges.
In addition to our standard line of gratings, we also produce customised gratings, allowing us to meet the critical demands made by quality-conscious users in spectroscopy and laser technology.
Carl Zeiss produces:
- Mechanically ruled plane gratings for the spectral range from 0.5 nm to 40 μm. Groove frequency 4 to 3000 grooves/mm.
- Holographically produced plane and concave gratings for the spectral range from 150 nm to 5 μm. Groove frequency 40 to 6400 grooves/mm.
- Diffractive, holographically produced beamshaping optics (HOE) for laser applications and beam splitter with a fixed and a variable splitting ratio, resonator gratings and collimators for laser diodes.
