Description
The Cometek Set of 6 Double Concave and Double Convex Lenses is a professional-grade optical toolkit engineered for comprehensive light physics exploration. This high-quality set includes three double convex (converging) and three double concave (diverging) spherical lenses, each precision-crafted with matched focal lengths of 10cm, 20cm, and 30cm. Every lens features a standard 2" (50mm) diameter and is processed from optically worked glass that undergoes rigorous polishing to offer highly reliable structural clarity. Designed with finely ground safety edges to ensure smooth handling, these optically true instruments are essential for visual demonstrations of light refraction, beam focal points, and image formation. They serve as an excellent educational asset for middle school, high school, and university physics laboratories, as well as an adaptable foundation for DIY science project kits.
Features
:- Optically True Performance: High-transmission glass minimizes light distortion, allowing students to observe clear focal properties and focal planes.
- Ground Safety Edges: Features micro-ground borders along the perimeter of the circular glass to facilitate clean, scratch-free mounting.
- Biconcave & Biconvex Geometry: Perfectly formed spherical surfaces allow accurate mapping of converging and diverging ray vectors.
- Multi-Length Array: Organized increments of 10cm, 20cm, and 30cm facilitate varied magnification power comparisons within a single set.
Applications
:- Demonstrating light ray tracking, focal point alignment, inversion dynamics, and image scaling benchmarks.
- Assisting hobbyists and students in constructing functional telescopes, microscopes, and custom light projectors.
- Exploring core principles of geometric optics, optical refraction indices, and ray convergence physics.
