Glass Cylindrical Lenses Bi-Concave Power 14D (Focal Length ~72Mm)

These glass cylindrical lenses are bi-concave with a power of 14D and a focal length of approximately 72mm. Their purpose is to focus light along a straight line, making them useful for looking at full paths of rays on paper, such as pencils of light emerging from the slits of a comb illuminated by a small lamp. These lenses are made of optically true glass with polished faces and ground edges. They are also known as square lenses or ray box lenses.

Key Features:

  • Optically true glass construction
  • Polished faces and ground edges
  • Bi-concave shape for focusing light along a straight line
  • Power of 14D and focal length of approximately 72mm
  • Ideal for observing full paths of rays on paper
  • Useful for examining pencils of light emerging from slits
