OP250 Handheld Fiber Optic Light Source
A configurable stabilized handheld fiber optic light source, Laser or LED, single or dual port configuration with selectable wavelengths and various power levels.

The OP250 is a configurable stabilized fiber optic light source available with a variety of LASERs or LEDs. Offered in a single or dual port configuration with selectable wavelengths, various power levels and industry standard optical interfaces. This instrument offers all the features and functions necessary for the development, testing and inspecting of optical components and cables. The stand-alone, internally powered module also connects to a USB port on any computer.
OptoTest offers drivers and applications which allow the user to perform common measurement tasks as well as data logging or time-stamped stability measurements. OPL-2 allows the user to adjust output power from 0 to 100%.
