Description
The Cometek 50mm Diameter Lenses and Mirrors Kit is a versatile optical bench set engineered to bring foundational light physics to life. Comprising a total of four precisely mapped items—including a double convex lens, a double concave lens, a convex mirror, and a concave mirror—this standard kit features a uniform 100mm (10cm) focal length across all components. Each piece is constructed from premium-grade, optically worked glass that has been meticulously polished to maximize clarity and minimize beam distortion during ray tracking exercises. The reflective mirror components are engineered with premium silvered back surfaces that are layered under a specialized protective coating to resist chipping, cracking, and weathering. Designed with masterfully ground edges to eliminate sharpness during handheld classroom tasks, this portable set provides the clean accuracy required for physics labs, school optics demonstrations, and independent science kits.
Features
:- True Spherical Precision: Perfectly ground geometric curvatures provide accurate, repeatable converging and diverging beam outputs.
- Protective Mirror Shielding: Durable backing paint layer guards the reflective silver elements against degradation and surface scratches.
- Smooth Perimeter Edges: Outer circular boundaries are meticulously ground down to facilitate safe manipulation and clean bench mounting.
- Highly Portable Layout: Slim, round modern form factors allow the lenses and mirrors to be easily integrated into mobile project cases or optical brackets.
Applications
:- Demonstrating image inversion, calculating focal points, mapping real vs. virtual vectors, and tracing beam paths.
- Comparing the behavioral differences between glass refraction paths and coated silver reflection surfaces side by side.
- Serving as authentic raw components for custom-built student periscopes, basic ray expanders, or experimental optical gear.
