Standard Spectrometer

Aneconomically priced Spectrometer, but capable of performing most of theexperiments like spectras, angle of prisms, refractive indexes etc. Consists ofheavy base with 170 mm diameter circle, divided 0 to 360 degrees, which rotatesindependently and has locking screw. Collimator: Fixed, with adjustable axis,objective lens with focusing system, variable aperture slit. Telescope:Moveable with set screw and fine motion screw, adjustable axis. Telescopepillar carries vernier scale for accurate measurements. Focusable objectiveLens. Ramsden Eyepiece with cross-wires and locking ring for focus lock. PrismTable: Provided with three leveling screws and engraved lines for prismplacement in experiments. Comes complete with everything you see in the pictures, Prism, Grating, Prism Clamp and Grating Holder.I purchased this instrument many years ago, in an effort to show my students the fundamental of light physics. I used it in the classroom to study various lamps spectra such as those from standard 60W bulbs, fluorescent tube, candles and a host of other like Argon. It is an \"eye opener\" and can be used for more scientific experiments in angles of deviation and so on which I never got into for lack of time.It was well taken care of. I paid it $250 at the time.
