Hoffman Engineering was founded in 1955. The initial charter of the company called for it to support the photometric needs of the aircraft panel and instrument manufacturers. Mr. Hoffman recognized the need and sought to fill it by performing photometric tests in his NBS traceable laboratory. In addition, he designed test equipment for sale to larger aerospace companies.

The Hoffman Engineering laboratory business grew with the aerospace industry in the United States. The scope of the business grew to include spectral testing, calibration of lamps and standards, and repair and calibration of photometric / radiometric equipment. Hoffman Engineering became the recognized leader in the testing of aerospace-related lighting equipment. Tests were performed on aerospace, ground support, shipboard, space-related and other higher technology lighted devices.

In addition to the work performed in its own laboratories, Hoffman began to develop its own line of photometric test equipment for sale to industry. Among the many products designed and manufactured by Hoffman engineering are contact photometers, luminance targets, integrating spheres, laboratory power supplies and luminance standards. The Hoffman luminance source has become the industry standard for the calibration of photometric equipment in lighting laboratories all over the world. Hoffman is fully qualified to perform tests to MIL-L-85762 and MIL-3009.
