From crystal growth, crystal orientation and cutting, to waveplate fabrication and coating, no other waveplate supplier has as much control over the fabrication stages as G&H.

As the world’s only entirely vertically integrated CdS, CdSe, and KDP waveplate producer, we deliver accurate performance for demanding applications. Our control over crystal growth benefits customers who need larger sizes, high laser damage threshold performance, or more accurate retardation tolerances.

For all wavelength ranges, we orient, cut, and polish the optical crystals for waveplate production. Polishing, coating, assembly, and metrology complete the manufacturing process. G&H has IS09001 certifications across all manufacturing facilities and AS9100C certifications across select facilities.
