Pronto-Si meter

Gentec Electro-Optics has launched a new member in its Pronto family of compact laser power meters. The Pronto-Si presents a 1cm2 silicon sensor, the largest in its category according to the company, perfect for measuring very low powers.

When combined with the integrated slide-in OD1 attenuator, the total power range of the Pronto-Si extends from 0.3nW to 800mW. The measurements are carried out in continuous mode, so the engineer can install the device in the laser beam path and leave it there indefinitely. The internal memory also allows transfer of data to a PC for further analysis. The sensor has a slim profile of 6mm, allowing it to be used in very tight spaces.
