Cometek Light and Optics Class Demo Kit 12 Acrylic Lenses, Ray Box with 5, 3 & 1 Light Beam Configuration

• Beam Array Settings: 1-Beam, 3-Beam, 5-Beam Parallel Output
• Optics Count: 12 Pieces Assorted Lenses

Features

• Configurable Slit Gate Ray Box: Built-in mechanical sliders allow instant switching between single tracking lines and multi-line parallel arrays for diverse experiments.
• High Transmittance Acrylic Lenses: Offers superior optical clarity mirroring premium glass while delivering maximum impact resistance against accidental laboratory drops.
• Precision Ray Tracing Sheets: Includes pre-measured angular grids and focal guidelines that help students accurately track and measure angles of incidence and refraction.
• Cool Running Light Source: Designed with passive ventilation slots to prevent the ray box enclosure from overheating during continuous classroom demonstrations.

Applications

• Focal Length Determinations: Allows high school students to physically measure and verify lens maker equations by tracking where light beams converge.
• Total Internal Reflection Demonstrations: Ideal for teaching the physics behind fiber optics by highlighting critical angle boundaries using semi-circular acrylic blocks.
• Chromatic Dispersion Analysis: Utilizes the high-output single beam through a triangular prism to split white light into its component spectral wavelengths.
• Corrective Vision Modeling: Serves as a clear visual aid to demonstrate how convex and concave geometries correct hyperopia (farsightedness) and myopia (nearsightedness).
