diffraction grating/holographic reflection grating/plane ruled grating |
 |
|
Grating is used in a wide range of applications, such as analytical instruments,optical communications,biotechnology,and medical instruments. Spectroscopes incorporating concave gratings are classified roughly into two groups: polychromators or monochromators. China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, transmission gratings and holographic gratings to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
Holographic gratings:
Specifications:
Ruled area: <=70 * 70mm
Wavelength range: 0.2-0.8um
Grooves per mm: 1,200 to 3,600L/mm
Diffraction: >70%
Ruled gratings:
Specifications:
Ruled area: <=70 * 70mm
Wavelength range: 0.2-15um
Grooves per mm: 50 to 2,400L/mm
Diffraction: >70%
Concave gratings:
Specifications:
Ruled area: <=70 * 70mm
Wavelength range: 200 to 900um
Grooves per mm: 490 to 1,200L/mm
Diffraction: >70% |
