Ключевые особенности семейства продуктов

This product has been superseded. Check this page for the new product.


This mid to high power handheld probe is so compact it fits in your pocket!


The touchscreen color LCD allows for a friendly user interface. You can make a measurement with just the touch of a button!

User Settable

You can set the wavelength, brightness and screen orientation to adapt to your application.

Data Logging

Save your data to the internal memory and then transfer it to your PC over the USB connection.

From Low to High Powers

Thanks to a low noise level and high damage threshold, the PRONTO can measure powers from 1 W to 250 W.

Fully Calibrated

The PRONTO-250 comes fully calibrated: every wavelength between 248 nm and 2.5 μm (YAG), and a real calibration at 10.6 μm (CO2). The PRONTO-250-PLUS has all these calibrations and is also calibrated for energy measurements.

Hands-Free Operation

Place it on a flat surface or use one of the 2 threaded holes that we have integrated in the casing for safe use with optical stands.

Versatile absorber suitable for most applications

Our H absorber offers a spectral response that is both broadband and spectrally flat, making this power detector a versatile solution that can cover most laser power measurement needs. Our proprietary manufacturing method also gives this absorber good damage thresholds, for both average power density and energy density. It has a high absorption capacity and, therefore, generates a relatively low percentage of back reflection.

Customers enjoy:

  • Useful for measuring a wide range of lasers
  • Low risk of damaging the equipment
  • Allows fast rise time







Traceable calibration provides the ability to trace the readings of laser output measurements to known international measurement standards determined by the National Institute of Standards and Technology (NIST). This ensures that the measurements taken by the instruments are reliable and accurate.

Benefits include:

  • Make valid comparisons of measurements taken by other instruments inside and outside your organization and over time
  • Comply with regulations or conform to industry standards
  • Avoid costly measurement mistakes in your operations
  • Improve customer confidence in your laser systems
  • Ensure laboratory experiment validity
  • Demonstrate measurement accuracy easily with the calibration certificate we provide
