The Gershun Tube Kit (GER-KIT) is an optical assembly that attaches to a spectrometer or SMA 905-terminated optical fiber to control the FOV of the setup. Each assembly comprises a conical base and middle and outer barrels that are threaded together. User-interchangeable apertures can be installed to adjust FOV at different increments from 1°-28°.
