The OPMSI is an ultra-slim optical power meter sensitive to the ultra-violet to near infra-red wavelength spectrum with a large area Si photodiode. It can be used to monitor optical powers in computerized optical setups. The device does not require a driver to operate, the host and device communicate only by a serial interface. Open source scripts are available for the Windows, Mac and Linux enviroments to display continuous optical power measurements. Compatible with Thorlabs SM1 thread adapter.
