Integrating Sphere Power Meter

BIM-740xU
Integrating Sphere Power Meter

The BIM-740xU integrating sphere power meter is based on a 2-inch integrating sphere (other sizes customizable) and different detectors such as UV-enhanced silicon (UV-Si), silicon (Si), and indium gallium arsenide (InGaAs) are selected for integration according to wavelength and sensitivity requirements. Its measurable wavelength range spans from 200 nm to 1650 nm. The BIM-740xU series power meters feature USB communication, eliminating the need for traditional meters by enabling direct connection to a computer for optical power measurement. Additionally, using a USB hub, the system can easily be expanded into a multi-channel optical power acquisition setup, supporting up to 8 channels for synchronized power measurement and display of multiple light sources.
