Flat Field Holographic Concave Grating

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, reflective gratings,holographic gratings,concave gratings etc. 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.
