Key Features
Laser diodes give 1, 3 or 5 parallel beams at the turn of a selector switch
Magnetic ABS body mounts on a magnetic whiteboard for vertical demonstrations
Biconvex lens, biconcave lens, rectangular prism, semicircular lens and triangular prism included
5V DC adapter included
Teacher’s guide, student lab manual and angular protractor sheet
On the protractor sheet, a single beam through the rectangular block lets students trace the bend at each face and work out the refractive index with Snell’s law, and the semicircular lens is used for critical angle work. Switching to 3 or 5 beams and placing the biconvex lens in their path shows the rays meeting at the focal point, so the focal length can be measured directly.
