Precision Optic Capabilities

PO Capabilities

Gooch & Housego’s precision optics group encompasses five operations, located in the UK and the US. Each operation is focused on expanding and developing its unique capabilities:

Across our facilities, we have experience and qualifications to serve our customers in defense, metrology, and medical sectors:

  • Export regulation compliant
  • ITAR compliant
  • ISO 9001 registered
  • AS 9100 registered

Non-linear optical crystal growth

Beginning with the raw chemicals we grow, orient, fabricate, finish, coat, and mount: Beta Barium Borate (BBO), Cadmium Sulfide (CdS), Cadmium Selenide (CdSe), Potassium Di-hydrogen Phosphate (KDP), Potassium Di-deuterium Phosphate (KD*P), Lithium Niobate (LnNbO3— often referred to as LN), and Tellurium Dioxide (TeO2).


Gooch & Housego has supplied superpolished optics to NASA’s Mars Curiosity mission and to international synchrotron experiments. Superpolished materials include N-BK7 Optical Glass, Calcium Fluoride, Crystal Quartz, Fused Silica, Nd:YAG, Sapphire, Silicon Carbide, YAG and ZERODUR®.


Gooch & Housego has four factories with thin film optical coating chambers, two based in the USA and two in the UK, offering coating based on the following coating technologies and coating types:

Thermal evaporationAnti-reflection (AR)
V-coats, double-V coats & broadband?AR
Electron beam gun evaporation (E-Beam)High-reflection (HR)
Ion assisted E-beam deposition (IAD)Metallic & Dielectric Mirrors
Ion beam sputtering (IBS)Bandpass filters: shortpass and longpass
Beamsplitters: polarizing and non-polarizing

Adhesive-free Bonding

Gooch & Housego’s adhesive-free bonding process, Hy-Per Bond™, activates precision optical surfaces prior to joining them, forming permanent bonds between the components that are resistant to humidity and cryogenic temperatures.
