Plane Ruled Grating

Plane ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Plane Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.

China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300 x 300 mm 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.

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

Concave gratings:
Specifications:
Ruled area: <=70 * 70mm
Wavelength range: 200 to 900um
Grooves per mm: 490 to 1,200L/mm
Diffraction: >70%
