WSS Optics

Diffraction Gratings

II-VI’s diffraction gratings feature precise periodic structures that achieve diffraction with high wavelength resolution. Our products are manufactured using II-VI in-house holography, ion-etching and replication processes. II-VI provides planar and concave reflection gratings and planar transmission gratings for various applications including in wavelength selective switches (WSS) in communications and in ultrafast lasers for materials processing.


  • Optics are available with Aluminum, Gold, Silver, Dielectrics and/or AR Coatings
  • All products are manufactured using volume precision grating fabrication techniques
  • Quality control parameters include: efficiency, stray light and laser damage tests
