Binary Phase Grating - Diffractive Grating


The Binary Phase Grating is a special case of 1D Damman grating with a duty cycle of 50% within a period. The HOLO/OR gratings are transmission grating.
In this section, we present our standard list of gratings with custom etching depth (modulation depth).
In addition to standard gratings, HOLO/OR can offer gratings with custom specifications (duty cycle, modulation depth, period, reflection or transmission grating).
