_x000D_ 1Pc Handheld Spectroscope Light Emission Spectroscopy Spectrum Physics Science Hobby _x000D_ _x000D_ _x000D_ _x000D_ 100% new and high quality _x000D_ Ever wonder how do we know the composition of suns and stars far away in the universe? The answer is spectrometer, the amazing equipment that can analyze light spectrum from any light source. You have read it in text books, now you can have it in your hand and observe Sun's emission spectrum yourself! _x000D_ 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). _x000D_ When use it for sun light observation, please use sun's reflected light from a mirror (Do not directly face the sun). _x000D_ 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. _x000D_ Specifications: _x000D_ Shell Color: Blue _x000D_ Material: plastic _x000D_ Size: 10x2.4x2cm/3.94x0.94x0.79 inch _x000D_ Quantity: 1 Pc _x000D_ Package includes _x000D_ 1*Spectroscope _x000D_ Only the above package content, other products are not included. _x000D_ Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
