Transmission-type grating (diffraction grating) "VPHG" [High diffraction efficiency]

Wasatch Photonics' transmission volume phase holographic grating: high diffraction efficiency! Low polarization dependence! Uniform performance! Robust!

Wasatch Photonics' Volume Phase Holographic (VPH) Gratings are products optimized for each application through multiple patented design technologies, ranging from stock items for R&D to custom gratings for OEMs. <Advantages> - No degradation occurs in the master and copies due to optical replication - Smoothly varying diffraction efficiency with respect to wavelength - High dispersion: 150 ~ nearly 6000 lines/mm - Low polarization dependence - Compact optical design due to transmission type - Wavelength tuning possible by varying the angle of incidence (AOI) - No ghosting, low scattering: 10 times less stray light than ruled gratings - Excellent durability due to a shielded structure with two substrates - Easy to clean - Custom sizes up to 300mm can be created
