Integrating sphere power meter: Fast and robust laser power measurement

Get the best of both worlds with our new integrating sphere power meters. This technology offers the fast risetime of photodetectors with the high average power of thermal detectors.

  • 12 mm Ø aperture
  • Measures up to 9 W of continuous power
  • Integrated signal processing with either USB or RS-232 output

 

Working principle

An integrating sphere detector is composed of two elements. First, light enters a hollow sphere through a small aperture and it diffuses inside the sphere with multiple reflections on the sphere's inner coating. Second, a small uniformly-lit aperture at another position in the sphere samples a portion of this diffused light and sends it onto a sensor. 

Laser specifications change over time for many reasons and it causes problems accross all industries. Learn about how laser output measurement solves numerous problems in YOUR industry. Download the guide below.

 

Gentec-EO's high-accuracy laser beam measurement instruments help engineers, scientists and technicians in all sorts of laser applications from the factory to the hospital, laboratory and research center. Learn about our solutions for these measurement types:

Basically, integrating spheres act as attenuators to allow for the use of smaller and faster detectors. Integrating sphere power detectors offer many advantages: fast response, high sensitivity, excellent spatial uniformity.

Tech note

If you would like to learn more on measuring laser power with the IS series, we invite you to check our tech note titled "Measuring laser power with the IS series: A versatile solution with fast reponse" available in our download center.

We currently offer only one model of integrating sphere power detectors but, as with all our other product lines, we are always ready to work with you on the design of a custom product that will perfectly suit your measurement needs.

This product will be shown at LASER World of Photonics Munich 2019 (booth B3.303).
