1Pc Handheld Spectroscope Light Emission Spectroscopy Spectrum Physics Science Hobby

and high quality Ever wonder how do we know the composition of and stars far in the universe? The answer is spectrometer, the amazing equipment that can analyze light spectrum from any . You have read it in text books, now you can have it in your hand and observe Sun's emission spectrum yourself! The spectroscope is made of optical glass. The composite prism and converging lens are installed in the vertical tube. Hold the spectroscope tube, the slit facing the light, a parallel beam is generated from the slit and converging lens. When the parallel beam pass through the prism, the dispersion spectrum can be directly observed. If the is fluorescent light, against the background of the continuous spectrum, one can see spectra of mercury (three straight lines). When use it for sun light observation, please use sun's reflected light from a mirror (Do not directly face the sun). This product can be used for a of light spectrum analysis. It is a high-resolution, simple, and economical product for hobbyist, amateur scientists, student lab and science fair projects.
