These mighty little curves of glass shed some light on learning the science behind optical principles. Also known as converging lens or positive lens, these Double Convex Glass Lenses from United Scientific are superior quality aids, each with two outwardly curved surfaces and a positive focal length of 100 millimeters (mm). Diameter of each lens is 38 millimeters (mm). The convex lens is used to solve the problem of farsightedness or Hypermetropia by bending the light ray, which shortens the focal length and makes the light ray focus on the retina in a proper way. It's also used in cameras for focusing and magnifying images. Use this pair for research studies or teaching demonstrations in geometric optics, physics, and other general optic lessons.
  • Double convex lenses consist of 2 outwardly curved surfaces and a positive focal length, commonly known to correct farsightedness
  • Teachers and students can use these superior quality glasses lenses for learning/teaching optical principles, reflection and refraction, general physics and more
  • Complement these convex lenses with concave lenses (sold separately) for learning about opposing optic forces for the best geometric optics demonstrations
Includes:
  • 2 Convex Lenses
