Optical demonstration set is used to demonstrate, experiment and make observations of how lenses can diverge or converge light. This set includes a lase ray box with 3 different settings, power adapter, cylindrical concave lens, cylindrical convex lens, prism, semi-circle optical block, trapezoid block, rectangle block, hollow semi circular block, mirror and charts. All the above materials are organized in carved foam in an aluminum alloy case.
Optics Experiment Set with Laser Ray Box
The hollow semi circular block is used to test the light refraction in liquids. Different liquids or different concentration of liquids have different refractive indexes. Set up your own refractometer to distinguish different liquids or to determine their concentration.
