BIM-710xU USB photoelectric power meter BIM-7101U Optical Power Meters Brolight
Detector Material: Si Wavelength Range: 380nm-1100nm Power Measurement Range: ~ 10mW
The BIM-710xU series USB optical power meter offers UV-enhanced silicon, silicon, indium gallium arsenide (InGaAs), and other detectors selected for wavelength or application requirements. It covers 200nm to 1650nm, with optional OD1/OD2 attenuators to increase the power-measurement range. USB communication eliminates the need for an additional conventional readout: installing optical-power-meter software on a computer enables live acquisition, analysis, and power monitoring. A USB Hub also allows a system with up to 8 channels to acquire and display power from multiple light sources simultaneously.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
