All our modern cameras have one common ancestor - The Camera Obscura: the light of the outside world falls through a pinhole onto the opposite wall of a room and produces an upside-down picture.

A small sensation for a small price: With this kit you can build a fully functioning zoom microscope with a variable magnification of 20x to 40x! The optical system, comprising 4 high quality acrylic lenses, is computer calculated and produces a sharp, colour-corrected image.
With this easy to build spectroscope you can examine the spectrum of any light source: glowing bodies (sun, incandescent light bulb), fluorescent lamps, etc. On the nano-meter scale you can read the wave length to 5 nm accuracy.
In the current hype for 3-D effects and movies it is easily forgotten that the basic principles for these have already been laid down 180 years ago by the English scientist Charles Wheatstone.
