Our essence

The decision of adopting “Partners for Accuracy” as our branding slogan is the result of a long evolution that spanned over more that 45 years. It came to us naturally since it represents our very essence. We have always aspired to be more than a simple supplier of state-of-the-art laser measurement technologies.

We truly believe that developing a very close partnership with our customers is essential and beneficial for every party. By definition, “partnership” means “aiming at the same goal” and “working together”. This is what is driving us. As for “Accuracy”, it does not solely refer to the precise measurements we are able to provide, but also to the complete understanding of our customers’ needs and expectations.

Finally, the key to our success is to focus all our energy into “rigorousness”. No matter what the situation, Gentec-EO is always proud to offer its customers the most accurate laser measurements as well as the most personalized help for the development of custom products and solutions.


The first laser energy meter in the world has been initially developed for internal use as Gentec Inc. were putting the first high repetition rate TEA CO2 lasers on the market in 1970.  Gentec, Inc. introduced the first pyroelectric joulemeters shortly after that. They were also the first to manufacture both thermopile and pyroelectric laser power and energy meters.

In the mid-1990s, the company introduced the WB series (today known as the W5 and W9 series) with an average power density damage threshold of over 100 kW/cm2 that is still unrivalled today.

In 2000, Gentec Electro-Optics, Inc. was formed from Gentec, Inc. so that it could focus entirely on laser beam measurement.

The acquisition, in 2010, of Spectrum Detector Inc. allowed to add measurement solutions for the new and rapidly expanding THz market, ultra-sensitive optical energy meters for applications down to femtojoules, instruments for pulse to pulse energy measurements up to 200 kHz and Optical TRAP detectors that act as primary calibration standards, to name a few.

Worldwide presence

Gentec-EO has an evergrowing presence everywhere around the world. We currently have partners in over 40 countries, and each year, we keep adding new partners. We also have a strong presence in most of the European and Asian countries and we now have offices in USA and in Japan, in addition to our headquarters in Canada.
