I decided to see their old photos and accidentally stumbled upon this interesting shtukentsiyu. Diascopy.
This is a device for viewing slides (for simplicity I will continue to call them cards) through the eyepiece with an external light source, although there with built-in lighting. In our case we consider diascopy easier.

Photo 1. Front view.





Photo 2. Rear view. The same eyepiece is where you want to stare))



Photo 3. Card. Those that are made of cardboard, unfortunately parted, but plastic as newcomers.



Photo 4.



Photo 5. Insert the card into diascopy and right at the light, look through the eyepiece.



Photo 6. The card, which saw above.



Photo 7. And as a bonus, my photo))
This is actually a very interesting thing. Today, for some time, I fell into childhood and ponastolgirovat. It is a pity that the picture can not convey the colors and emotions that I have received today.
That's all I wanted to say.
