Gooch & Housego was established as an optical radiation instrumentation, standards and calibration laboratory in 1970. Forming the nucleus of the company were two former NIST (National Institute of Standards and Technology, formerly the National Bureau of Standards) physicists who had individually made significant contributions to the field of spectroradiometry and electro-optical technology.
The company was established to eliminate a void that existed in industry, government, and academia in the area of optical radiation standards, calibration services, and measurement instrumentation. As the result of a constant emphasis on precision and accuracy in these endeavors, the company has earned a worldwide reputation for high quality instrumentation and unique solutions to the most difficult and complex light measurement challenges.
The key to Gooch & Housego’s capabilities lies in the nearly 100 collective years in light measurement accumulated by senior personnel. The contributions to optical radiation measurement by the company’s former resident scientist alone, Dr. Richard Young, span more than 30 years. Other key personnel’s education, involvement in industry organizations, and hands-on experience make them among the most respected professionals in this field.
Though initially patterned after the procedures of NIST laboratories, Gooch & Housego has evolved its practices more toward handling practical calibration problems. As a result, the company provides unique calibration services that include, but are not limited to, providing spectroradiometric, radiometric and photometric standards.
Most of the standards and calibration services supplied by Gooch & Housego are directly traceable to NIST. In those cases where NIST standards are not available, standards from other national laboratories or standards set up at Gooch & Housego are used.
Gooch & Housego maintains the following primary shelf standards:
- Spectral Irradiance Standards
- Ultraviolet Irradiance Standards
- High Intensity Irradiance Standards
- Total Irradiance Standards
- Spectral Radiance Standards
- Diffuse Spectral Reflectance Standards
- Specular Spectral Reflectance Standards
- Silicon Detector Standards
- Germanium Detector Standards
- Pyroelectric Detector Standards
- Luminous Intensity Standards
- Color Temperature Standards
- Radiance Temperature Standards
