Compact Fiber Interferometer
This is a Rugar-type all-fibre interferometer system which can be used for AFMs and other experiments. It includes a laser system with 1310 nm wavelength, a 2×2 fibre coupler and two photodetectors. USB Fibre Interferometer is really small in comparison to equivalents thanks to the advanced electronic design. Low noise driver on the board regulates the laser power. The output fibre, which goes to the interferometer is connected to the module by an FC/APC connector at the front panel. Measurement of interference pattern during the positioning of the fiber slider at the back of the cantilever, extraction, and display of relevant parameters for fiber alignment: pattern, itself, visibility, slope of the pattern. Other wavelengths can also be customized.
