Muy simple peo correcto
For the price its good, For educational at young age. The plastic holder will be the weak link,pun intended. With some cardboard you can see differences between spectrum of various emitters, sun, led, laser(pointer) intrc. Might be more practical if you take just the prism ... you will be able to guess the wavelength when using a webcam as detector . was delivered in time and without damage was reasonably packed.
So poetic, relaxing to see the light expanded to all its color components. Interesting to see that "filament" lighting (old bulbs) provide more colors than white LED lightings.
The stand has a cheap feel to it, but the prism is quite excellent. Although it's all plastic and the price is low, it's decent and I'll be ordering some of the other shapes offered.
Bit flimsy, and could easily fall apart if knocked, but a good prism and an interesting stand to go with it.
Dieses optische Prima ist ein effektvolles "Experimentalspielzeug" . Preis und Leistung sind hervorragend.
good prototype for my grandson education ...I hope he would like it ! Good job Banggood!
