Hartley's Optical Disk with Accessories and Light Source

Hartley's Optical Disk with Accessories and Light Source — Classroom Optics Demonstration Kit

Also known as Hartley's Optical Disk, this set demonstrates the refraction of a light beam as it passes through various lenses. It features a rotating disk with a 23 cm diameter and a 360-degree scale, a complete set of magnetic lenses and acrylic prisms (triangular, trapezoidal, semicircular prisms, plus convex and concave lenses), as well as an apparatus for generating light rays together with diaphragms. All components are mounted on a stand for stable demonstrations.

What’s included

• Rotating disk with 23 cm diameter and 360-degree scale
• Magnetic lenses
• Acrylic prisms: triangular, trapezoidal, semicircular
• Convex and concave lenses
• Light-ray generating apparatus with diaphragms
• Stand-mounted assembly

Educational applications

This kit enables students to observe how light bends and refracts through different optics elements, illustrating fundamental principles of optics, refraction, lens behavior, and prism dispersion in a clearly visual, hands-on way.

IMPORTANT: a power adapter is required for the light source – sold separately!
