Gentec Electro-Optics, Inc.

We are proud to offer an extensive line of power and energy detectors for the terahertz spectrum. 

Our pyroelectric-based terahertz measurement systems that are very easy to use at room temperature. 

Unlike photoconductive and photovoltaic detectors, our terahertz detectors are not limited to a small part of the electromagnetic spectrum. They are truly broad-spectrum detectors, sensitive from 0.1 μm to 3000 μm (EUV, FAR IR, and THz). Any and all radiation absorbed by our coatings or pyroelectric crystal will result in a measurable signal. 

LEARN ABOUT TERAHERTZ MEASUREMENT

Profiling a laser beam provides very useful additional information, like spatial energy or intensity distribution, beam widths, centroid, ellipticity and orientation, that helps you determine if your laser-based systems are operating optimally. 

BEAMAGE is the most cost-effective USB 3.0 beam profiling camera on the market. It is available for UV to IR wavelengths and in 3 sizes. It comes with an intuitive and complete software that features useful tools and functions. Its calculations are ISO-compliant. 

BEAMAGE-M2 measures your laser’s M² factor, which indicates how close a laser is to being an ideal Gaussian beam.

With our standard power detector offering, you can measure power from 0.3 nW to 100,000 W. To measure such a wide range, we rely on five state-of-the-art technologies:

• Thermal detectors, for most applications
• Pyroelectric detectors, for very low power
• Photodetectors, for low power
• Integrating sphere detectors, for fast response time
• Water calorimeters, for very high power

Each technology is used to measure within a defined laser power range and to work with specific laser specifications such as power density, wavelength and beam diameter.

To quickly find the detector you need, we recommend that you use our product finder.

We design and manufacture a wide range of professional-grade, high-accuracy laser energy meters. 

Our energy detector offering is made of four technologies:

• Pyroelectric detectors, for most applications
• Photodiode-based detectors, for low energy
• Integrating sphere detectors, for high repetition rates
• High-energy calorimeters, for extreme beams

Each one is used for energy measurement within a specific range and designed to work with specific laser specs such as beam dimension, wavelength and repetition rate.

The simplest way to determine which energy detector best fits your needs is to use our product finder.
