Description

Designed for deeper investigation into optical refraction, the Biconcave Lens (75mm diameter, 200mm focal length) provides a practical tool for observing light behaviour through diverging lenses. Its polished, optically worked glass ensures safety and clarity, ideal for experimental physics activities. The double concave structure enables the spreading out of light rays, generating a smaller virtual image.

Educational Benefits:

  • Demonstrates advanced properties of light through hands-on exploration.
  • Encourages analytical thinking and scientific inquiry.
  • Links physical optics with real-world vision correction solutions.
  • Supports cross-curricular learning in STEM programs.

Classroom Ideas:

  • Build optical setups to explore different magnification effects.
  • Analyse ray behaviour with varied incident angles.
  • Design comparative studies across lenses with multiple focal lengths.
  • Integrate into a full optics unit with other light-manipulating tools.
