Laser power meter measures less than 1nW

In the area of the silicon sensor, this device is just 6 mm thick and allows for power measurement even in very tight spaces.

Thanks to the highly-sensitive silicon sensor with an effective aperture of 10 mm x 10 mm, it is possible to quickly and precisely measure power levels significantly less than 1nW.

Without the need for extra space, the range of measurement can be expanded into the three-digit mW range due to an integrated, "upstream" OD1 attenuator. Low laser power in the wavelength range from 320nm to 1,100nm can be measured "in a blink."

The PRONTO-Si is available at Laser Components. It is an aide for laser safety officers – whether for use in the power measurement of cw laser modules to check the correct laser class designation or in the testing of structural and equipment laser protective measures.

The charging of integrated Li-ion batteries (for a runtime of up to 17 hours), the readout of internal measurement data memory (for 50,000 measurements), and future software updates can be carried out via the existing mini USB connection.
