  • IS50A-1KW-RSI: fast kilowatt-level power meter
    The IS50A-1KW-RSI can measure average powers of up to 1 kW in less than 200 ms. This allows for measurements that were not possible before, such as following the complete ramp-up of high-power laser sources, or tracking fast changes in laser power....

  • New integrating sphere detector for fast laser power measurement up to 1 kW

    Gentec-EO recently launched IS50A-1KW-RSI, the fastest kilowatt-level laser power detector on the market. With a measurement capability that ranges from 0.2 mW to 1000 W and a rise time of only 0.2 s, the IS50A-1KW-RSI opens up new measurement possibilities such as following the complete ramp-up of high-power laser sources, or tracking fast changes in kW-level laser power. The integrating sphere’s proprietary coating was designed to handle high laser power density, and its NIST-traceable calibration provides accurate, reliable results. Plugs directly in a computer via USB or RS-232 for a simple, quick setup.

    Why use Gentec-EO’S integrating sphere technology

    There are numerous advantages to use an integrating sphere detector when measuring laser power.


    First, it lets you follow the ramp-up of a high-power laser because such detectors measure laser power extremely fast, with a 0.2s rise time. Integrating sphere power detectors offer many advantages performance-wise: fast response, high sensitivity, excellent spatial uniformity.

    Cost-efficient solution

    The same detector can be used for measuring several laser systems because the dynamic spectral range is very wide. Indeed, these detectors have a NIST-traceable calibration for their entire calibrated spectral range, and this calibration is valid from the noise floor to the maximum power: from tens of mW to 1000 W!

    This results in significant savings for customers who have many lasers to measure. Also, you do not need to purchase a display device to read your measurement since our INTEGRA technology is integrated into it. Just plug the detector into your computer.

    Improved safety

    If you are particularly concerned about safety in your work environment, using an integrating sphere detector instead of a thermal detector is even safer because back-reflections are much weaker.

    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.

    Basically, integrating spheres act as attenuators to allow for the use of smaller and faster detectors.
