This demonstrations optics set uses a Laser Ray Box that has bright, well-defined rays because it uses lasers rather than an incandescent light source. The Laser Ray Box projects five 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 lenses inside the box.
The ray box has a magnetic back for mounting on any steel board. The unit is powered by an included AC adapter.
This exceptional optics set includes six magnetically-backed templates that have guidelines showing where to put components to perform different demonstrations, including:
- Modeling the human eye and eyeglasses
- How a camera works
- Two types of telescopes
- Spherical aberration
- Refraction and reflection
Each component has a magnetic backing for mounting on any steel board.
