The OP1550 is a high performance, user friendly Fabry-Perot interferometer. It can be used to interrogate Fabry-Perot sensors, such as the Optics11 fiber-top cantilevers, or any custom cavity providing an optical reflection. The OP1550 features real-time linearization up to a bandwidth of 75 kHz, providing a linear range that can be scaled from nanometers up to millimeters. It operates stand-alone with an integrated display, or via PC software.
The noise performance of the standard version is as low as 3 pm/ √Hz. The output is available as an analog signal, as well as a digital signal that can be stored on a PC.
