1pc Handheld Spectroscope Light Emission Spectroscopy Spectrum Physics Science Hobby

and high qualityEver wonder how do we know the composition of suns and stars far in the universe? The answer is spectrometer, the amazing equipment that can analyze light spectrum from any light source. You have read it in books, now you can have it in your hand and observe '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 light source is fluorescent light, against the background of the continuous spectrum, one can see the line spectra of mercury (three straight lines).When use it for light observation, please use 's reflected light from a mirror (Do not directly face the ).This product can be used for a variety of light spectrum analysis. It is a high-resolution, simple, and economical product for hobbyist, amateur scientists, student lab and science fair projects.Specifications:Shell Color: BlueMaterial: plasticSize: 10x24x2cm/394x094x079 inchQuantity: 1 PcPackage includes1*SpectroscopeOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
