Gentec-EO is pleased to announce the addition of a new member to the Pronto family of Compact Laser Power Meters. As its name indicates, the Pronto-Si presents a Large 1 cm2 Silicon Sensor, the largest in its category, 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 0.3 nW to 800 mW. The measurements are done in Continuous Mode, so you can install the Pronto in the laser beam path and leave it there indefinitely. The internal memory also allows you toAcquire Data and Transfer it to a PC for further analysis. The sensor part has a Very Slim Profile of only 6 mm, allowing it to be used in very tight spaces.
