Use this ray box on a whiteboard to vividly demonstrate optical principles.
- Produce rays using an incandescent lamp rather than LED or laser
- Attach ray projector to veritcal surface using suction cups
- Great for use on non-magnetic surfaces
This projector provides up to five well collimated light beams that trace clear optical paths along a chalkboard. The fixed central beam establishes the optical axis. The other rays may be adjusted to desired angles to demonstrate spherical aberration.
Delivery information: Includes lamp (12 V, 55 W).
