This list includes only major pieces of equipment available at OCF. It is not complete, some items will be added later. Also, we have a lot of general purpose and application-specific optics: mirrors, lenses, filters, polarizers, and optomechanical hardware. Labview drivers provided by manufacturers or developed in-house are available for the most of instruments with computer interface. Complete Labview routines have been developed for the standard experiments as well. If the capability you need is not listed here, please contact OCF staff. We can develop the experiment for you, customize the existing instrument, or refer you to another facility.
