N/A

1Grating will perform with high efficiency over significantly larger spectral range and range of angles- please inquire.

2P-polarization: electric field vector is perpendicular to the grating lines. S-polarization: electric field vector is parallel to the grating lines.

3Worst case in the operational wavelength range for optimal polarization.
