Geometrical optics with pentalaser - version with magnetic board and red pentalaser
Product Code : SCL-OS-12810
Quick Answer: Geometrical Optics with Red Pentalaser and magnetic board is a ray optics set in which a red multi-ray laser and magnetic optical elements are arranged on a magnetic board. It is used to trace reflection and refraction through mirrors, lenses and prisms.
Last updated: October 2026
Key Features
Red pentalaser produces multiple visible laser rays
Magnetic demonstration board holds and positions the optical elements
Magnetic mirrors, lenses and prisms can be moved and angled quickly
Ray paths can be marked to study reflection, refraction, focal point and deviation
Suited to class demonstrations as well as student practicals
Because several rays are visible at once, students can see a converging lens bring rays together or a diverging lens spread them, rather than inferring it from a single beam. Teachers use the board to build ray diagrams live, then change the angle or position of a component to show how the paths respond.
Frequently Asked Questions
What does the magnetic board add to this geometrical optics set?
It holds the pentalaser and the magnetic optical elements in place and lets them be repositioned quickly, so the ray paths stay steady while they are observed and marked.
