Color blindness test bookNice color blindness book with nice illustrations for testing and demonstrating color blindness. Both numbers and figures appear in the book.
Color mixer, blue, red and green
Color mixer, blue, red and greenThe color mixer allows you to regulate the three primary colours, red, green and blue, and creates shades of the light spectra that these colors provide.

Commutator for student coils
Commutator for student coilsUsed for experiments with DC motors and generators.
Commutator/collector contact spring
Commutator/collector contact springContact spring made from phosphor bronze.
Compact spectroscope
Compact spectroscopeHand-held spectroscope in a metal housing, which allows qualitative observation of the spectrum from spectral lamps and other light sources.
This robust spectroscope is of very high optical quality and requires no adjustment. An optical grating with 600 lines per mm and a prismatic optical system ensures sharp spectra without distorted colours.
Compact spectroscope, pocket size
Compact spectroscope, pocket sizeA cheaper alternative to the popular hand-held spectroscope TE313, where the price difference is due to a lower sharpness in the observation of e.g. spectral lines and that it is only 55 mm long.
Compass needle
Compass needleMagnetic steel needle with nickel-plated brass bearing. Requires base no. 341500.
