Bi-convex Lens 50mm FL 500mm

This large focal length Bi-convex Lens (50mm diameter, 500mm focal length) is designed to demonstrate long-distance light convergence. Its gentle curvature and precision-crafted optical glass enable learners to observe how even distant focal points can produce image clarity. Ideal for high-level optics demonstrations, it supports detailed learning about light paths and image projection.

Educational Benefits:

• Encourages understanding of advanced light refraction principles.
• Demonstrates how focal length influences optical instrument design.
• Supports student-led investigations in physical sciences.
• Provides opportunities for modelling lenses used in telescopes and cameras.

Classroom Ideas::

• Integrate into telescope-building challenges for senior students.
• Examine the differences in focus sharpness using varied focal lengths.
• Compare beam width and convergence through multiple lenses.
• Explore image formation at different object distances.

Specifications:

• Lens type: Bi-convex
