Very popular and schematic aid for the explanation of the principles of reflection and refraction of light in the optic environment.

More details

Popular and solid aid for an explanation of reflection and refraction principles of light in an optical environment. The aid is built on a circular base, which can be rotated around the axis. The angle of refraction or reflection can be detected by the light beam reflected on the angular scale. The half-circle optical transparent module allows us to measure the material index of refraction taking into account Snell`s law. The 1mW semiconductor Laser Line Box with a wavelength of 635 nm is used as the light source. Due to the collimated laser beam, the angles of refraction and reflection are excellently displayed, therefore the experiment is very clear and students can arrange the practical exercise very easily and quickly.

The high didactic value of the aid is reached concerning its following features:

  • high clarity of the experiment
  • easy arrangement
  • up to date laser technology
  • acceptable price

The set consists of:

  • metal base with a rotating circle with angular scale
  • semi-circle optical transparent module 
  • Laser Line Box - laser class: 2
  • battery box (2x1,5V, AA size)
  • connecting cables
  • power supply (3V / 500mA)
