Coatings
Gratings and mirrors:
Depositions of reflective metallic coatings are performed with cryogenic evaporation in our production laboratory warrantying grating performance.
Gratings are provided with a standard aluminum coating. Other standard coatings (to improve reflectivity in certain spectral ranges) may also be requested.
We suggest:
- Above 6000 Å : IR gold
- Between 1500 Å to 6000 Å: Al
- Between 1150 Å and 1650 Å : Al+MgF2
- Below 1000 Å : UV gold or platinum or nickel
Additional coatings for specific VUV and soft X-ray applications, such as carbon or SiC are available on request for your specific applications.
VUV & soft X-ray gratings:
Reflectivity depends on the light beam incidence angle. HORIBA Jobin Yvon can help you review reflectivity and efficiency values according to your incidence angle and wavelength range.
Ordering Information
Al + MgF2(optimized 1216-1610 Å) | 50 000 001 |
IR Gold | 50 000 003 |
UV Gold | 50 000 004 |
UV Platinum | 50 000 005 |
- Reflectivity for Al Coating incident angle = 0°, unpolarized light
- Reflectivity for Au Coating incident angle = 0°, unpolarized light
- Example of Reflectivity for Different Metallic Coatings incident angle = 80°, unpolarized light
