BragGrate™ Holographic Optical Elements (HOE)

BragGrate™ (or BG™) is a trademark of OptiGrate for volume Bragg gratings (VBG) produced by a refractive index modulation in the volume of a photosensitive BragGlass™. Depending on the diffraction angle and orientation of a grating in the plate, one can distinguish several types of VBG diffractive optical elements.
