Dickson
gratings®
outperform all other grating technologies because of their
high dispersion combined with high diffraction efficiencies
in both S & P polarizations and low PDL.

1.
These are approximate groove spacings to show typical performance
characteristics. Dickson Gratings®
can be made for other telecom wavelength ranges such as S or
L Bands and other CWLs. We reserve the right to change
these as necessary.
2. Assumptions: Fused silica prisms and substrates, right
angled prisms, and incoming/exiting beams normal to the back
prism surface.
