The glass convex lens with a 75 mm diameter and a focal length of 20 cm is an essential optical component widely used in educational, scientific, and experimental environments. Carefully crafted from high-quality optical glass, this convex lens demonstrates excellent clarity, precision curvature, and superior light transmission. Its spherical outwardly curved surface allows it to converge parallel rays of light to a single focal point, making it an ideal instrument for demonstrating and understanding fundamental optical principles such as refraction, convergence, focal length, magnification, and image formation.
Description
Convex Lens Dia 75 mm FL 20 cm for Light Experiments
The Convex Lens Dia 75 mm FL 20 cm is designed for accurate observation of light behavior in physics laboratories and classrooms. Its large 75 mm diameter allows effective light collection, which helps produce bright and clear images during optical experiments. The precisely calibrated 20 cm focal length supports balanced demonstrations of real and virtual image formation.
Convex Lens Dia 75 mm FL 20 cm for Image Formation Study
This glass lens enables students to explore ray diagrams, focal points, and magnification through hands-on learning. Learners can vary object distance to observe changes in image size and position. Therefore, abstract textbook concepts become easier to understand through direct experimentation. The lens works well with optical benches and standard laboratory holders.
High-Quality Glass for Clear Results
The use of quality optical glass reduces chromatic and spherical aberration. Polished surfaces and smooth edges provide clear, distortion-free viewing and safe handling. These features ensure reliable performance during repeated classroom demonstrations and student practicals.
Suitable for Educational Optical Setups
The convex design supports experiments related to refraction, lens formula verification, and optical axis alignment. It also serves as a component in basic optical instruments such as magnifiers, projectors, and simple telescope or microscope assemblies. This versatility makes it useful across multiple learning levels.
Durable and Easy to Handle
The lens remains lightweight yet strong, which allows easy storage and transport between laboratory setups. The robust glass construction resists chipping under standard laboratory conditions. As a result, the lens maintains consistent clarity and performance over time.
This product is intended strictly for education and demonstration use only and not for industrial, medical, or commercial optical systems. Overall, the Convex Lens Dia 75 mm FL 20 cm offers precision, durability, and clarity, making it a dependable tool for teaching and learning the fundamentals of geometrical optics.
