High-Resolution Pocket Diffraction Spectroscope for School Lab & Solar Light

Ever wonder how do we know the composition of suns and stars far away in the universe?<br> Pocket Diffraction Spectroscope Handheld Spectroscope Light Used In School<br> The answer is spectrometer, the amazing equipment that can analyze light spectrum from any light source.<br> You have read it in text books, now you can have it in your hand and observe for Sun's emission spectrum yourself<br> The spectroscope is Constructed from optical glass.<br> The composite prism and converging lens are installed in the vertical tube.<br> Hold the spectroscope tube, the slit facing the light, a parallel beam is generated from the slit and converging lens.<br> When the parallel beam pass through the prism, the dispersion spectrum can be directly observed.<br> If the light source is fluorescent light, against the background of the continuous spectrum, one can see the line spectra of for mercury (three straight lines).<br> When use it for sun light observation, please use for sun's reflected light from a mirror (Do not directly face the for sun).<br> This item is suitable for a variety of light spectrum analysis.<br> It is a high-resolution, simple, and economical product for hobbyist, amateur scientists, student lab and science fair projects.<br> Specifications:<br> for Shell<br> Quantity: 1 Pc<br> Thank you<br> 1 x Handheld Spectroscope<br> 1 x User Manual<br> Material: Optical Glass<br> Colour: Blue<br> Size: 10x2.4x2cm/3.94x0.94x0.79"<br> Included in the package:<br> Note:<br> Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid<br> Due to the difference between different monitors, the picture may not reflect the actual color of the item.
