Spectrometer Prism, 1 Each

The Spectrometer Prism by United Scientific is an accessory prism designed for United Scientific's Intermediate Spectrometers, including the version with 30 mm optics. It sits on the spectrometer's 7 cm prism table for dispersion, apex-angle and minimum-deviation measurements. Physics teachers and lab coordinators order it as a replacement or spare so a damaged prism does not take a spectrometer station out of service.
