1Pc Light Emission Spectrum Physics Science Hobby

Packing, shipping, shipping is all good. It's funny to say that I was looking at the wrong place at first and thought I was sent out of air. It is made of plastic, not neat, but for this cost I consider it normal. Works and performs its function. With its help, on an ambulance took off the phone spectrum of daylight, and then several inexpensive filters UHC, Oiii, Moon skygloy. The spectrum of the sun has absorption lines (froungoferov lines) (vertical), for which the wavelength is known and focusing on which, you can estimate the width of of of of

A great toy for a child. I tried making a diffraction spectroscope, but its picture quality of this toy turned out to be much better :-) The spectrum of the sun is perfectly visible, dark lines are visible-you know in honor of whom they are named. The spectrum of the lumen lamp is well visible. We experiment further, the child is delighted. One small flaw is the instruction in Chinese, but Google heals everything!

Arrived on South urala fast enough, in 14 days missed margin. We must look by Prism, where more glass. Glass, by the way, hanging and almost falls, it must be something to fix the firm. Now it is one of my favorite toys.

All is well, with the help of the adapters available and such a mother has fixed the spectroscope to the SLR, now you can shoot the spectrum of transmission of light filters. Sent was fast, packed well.

It seems to work, but how to use it, I did not understand. Perhaps you need to attach to the smartphone video camera. I'll try it tomorrow.

Seller fast forward, everything is fine. Do not just take care. Look into small stёklyshko, and we must look to the great :)

good quality for price. a bit difficult to adjust focus, but high enough quality to observe Fraunhofer lines.

Entertaining toy, corresponds to the description and reviews. Thank you!

All is excellent goods intact, I recommend the seller

A toy, dirty optics, but informative.
