Description

This demonstration ray optics system uses a Laser Ray Box which has bright, well-defined rays because it uses lasers rather than an incandescent light source. The Laser Ray Box projects 5 parallel laser beams onto any flat surface. It contains five 1 mW diode lasers (wavelength 635 nm). The laser beams are spread out into clearly visible lines by cylindrical lens inside the box. The beam paths can be observed from a relatively long way in a dark room.

White acrylic board with linear and circular scale is provided for display of lines of light and measurement of geometric components like focal length of lenses etc. All optical components are made of transparent acrylic material with one side grounded.

Experiment Performed

• Law of refraction
• Law of reflection
• Total reflection
• Determining the focal length of curved mirrors and lenses
• Lens laws
• Beam paths in cameras, microscopes and telescopes

Features

• All optical components are made of transparent acrylic with one side grounded
• Laser ray box has good line of vision with less power
• Board contain both linear and circular scale
