Description

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 **0x**0mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from *0 grooves per millimeter to ***0 grooves per millimeter, wavelength from 0.2 micron to *5 microns. Holographic gratings: Specifications: Ruled area: <=*0 * *0mm Wavelength range: 0.**0.8um Grooves per mm: 1, **0 to 3, **0L/mm Diffraction: >*0% Ruled gratings: Specifications: Ruled area: <=*0 * *0mm Wavelength range: 0.***5um Grooves per mm: *0 to 2, **0L/mm Diffraction: >*0% Concave gratings: Specifications: Ruled area: <=*0 * *0mm Wavelength range: **0 to **0um Grooves per mm: **0 to 1, **0L/mm Diffraction: >*0%
