Cylindrical Lens
| Cylindrical Lens (also named Cylinder Lens) is used to
correct astigmatism in the eye, and, in rangefinders, to produce
astigmatism, stretching a point of light into a line.. They are
available in either plano concave or plano convex configurations.
Plano Concave Cylindrical lenses have a negative focal length and
are used for image reduction or to spread light. Plano Convex
Cylindrical lenses have a positive focal length, which makes them
ideal for collecting and focusing light for many imaging
applications. |
Applications:
●Bar Code Scanning
●Projection Optics System
●Laser Measurements Systems
● Holography
