N/A

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

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

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