Crystal OpticsGooch & Housego produces many different crystals from a variety of materials. We grow, orient, fabricate, finish, coat, and mount BBO, CdS, CdSe, KDP, and KD*P crystals in housings with apertures from 3 mm to larger than 300 mm.We manufacture our crystals to work in optical components such as acousto-optic modulators, lithium niobate Mach-Zehnder modulators, Pockels cells, waveplates, and harmonic generating crystals. Large KDP and KD*P crystal plates grown, cut, and finished by G&H are used at The Commissariat à l'énergie atomique et aux énergies alternatives (CEA) and National Ignition Facility (NIF) for laser fusion.
G&H has extensive facilities for transmission and reflection interferometry, as well as contrast ratio measurements. We can measure insertion loss, uniformity of birefringence, and other important characteristics. Our experience growing Lithium Niobate dates back to 1967, producing the first commercially available material. Since that time we have constantly refined the growth and material processing to be able to produce the highest quality, most consistent lithium niobate.
Crystal Optic products
IR WaveplatesCadmium Sulphide (CdS) and Cadmium Selenide (CdSe) waveplates are manufactured from original crystal growth to final product for wavelengths greater than 3µm. Very large, greater than 1 m, Di-Hydrogen Potassium Phosphate (KDP) waveplates are also available.
Space qualifiedMany of our photonic solutions are qualified for space or are currently deployed. We understand how to develop, design, and manufacture for extremes of temperatures, radiation, shock, and vibration. We perform extensive qualification testing during engineering builds and flight hardware qualification.
ITAR compliantWe have extensive capabilities and experience supporting and managing the unique needs of government sponsored development programs. US customers can work with and source directly from a US-based supplier who can leverage capabilities and products across all worldwide divisions of G&H.
From prototypes to full-scale productionAt G&H, we have the ability to produce single prototypes and the manufacturing capacity to make fiber optic components, assemblies and modules by the thousands. We can support your needs from commercial off-the-shelf products to customized complex solutions to meet your most demanding fiber optic requirements
