Descripción del producto

The concave grating has the advantage of being able to constitute a spectroscopic system without any assistance from concave mirrors or similar types of image-forming elements. For this reason,the Concave 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.
