Portable photodiode-based laser power meter for up to 800 mW.

This low power laser probe is so compact it fits in your pocket!

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

Thanks to its very low noise level of only 10 pW, the PRONTO-SI measures powers as low as 0.3 nW

Just slide the OD1 integrated filter to the "on" position and you can measure up to 800 mW of continuous power.

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

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