Spectral glasses

In this way you can check whether these are continuous and correspond to natural sunlight. That makes sense, is very simple and is also fun, because a look through the spectral glasses opens up a wonderful world of colors.

With the spectral glasses, children (school classes) can also get to know the principle of light easily and playfully.

Note: These glasses are not suitable for looking directly into the sun as there is a risk of blindness.
