Glass Cylindrical Lenses Plano-Concave Power 14D (Focal Length ~72Mm)
These glass cylindrical lenses are plano-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 examining the full paths of rays on paper. For example, they can be used to study the pencils of light that emerge 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, and are also known as square lenses or ray box lenses.
Key Features:
- Plano-concave design for focusing light along a straight line
- Power of 14D for clear and precise vision
- Focal length of ~72mm for optimal viewing distance
- Made of optically true glass with polished faces and ground edges
- Useful for observing full paths of rays on paper or other surfaces
- Also known as a square lens or ray box lens
