The Cometek 4-Piece Double Convex and Double Concave Lens Set is an essential toolkit engineered for comprehensive optical experimentation and physics demonstrations. This high-quality set features a versatile combination of two double convex (converging) lenses and two double concave (diverging) lenses, each precisely manufactured with a 50mm diameter and available in dual focal lengths of 10cm and 20cm. Crafted from premium, highly polished optical glass, these lenses ensure exceptional light transmission, minimal distortion, and precise refractive indexes. Each lens is finished with professionally ground edges to guarantee safe handling in fast-paced student environments.

Features

High Clarity Spherical Surfaces: Both sides of the lenses are precisely curved and polished to minimize optical aberrations and ensure uniform light bending.
Comprehensive Convergence & Divergence Studies: Allows instructors to simultaneously demonstrate how convex lenses focus light rays to a point while concave lenses spread them apart.
Durable & Scratch-Resistant Construction: Made from robust glass that withstands repeated laboratory handling, cleaning, and storage without losing optical clarity.
Optimized for Optical Benches: The physical dimensions are tailor made for seamless compatibility with standard school and university physics laboratory equipment.
Accurate Focal Length Tolerances: Meticulously calibrated during production so that experimental calculations closely align with theoretical physics equations.

Applications

High School & College Physics Labs: Acts as a foundational teaching aid for mandatory STEM and optics modules within science curriculums.
Science Fair & DIY Projects: Ideal for students and hobbyists building home science setups, periscopes, or customized magnifying glasses.
Optics Research & Testing Workshops: Used in basic engineering and development environments for rapid prototyping of light-focusing pathways.
Teacher Demonstration Kits: Perfect for science instructors requiring reliable, highly visible equipment for classroom lectures and desk demonstrations.
