Plano Concave Cylindrical Lens

Name: Plano Concave Cylindrical Lens
Brand: ECOPTIK INDUSTRIAL PTE.LTD.

Plano concave cylindrical lens is an optical element with one surface being a plane and the other surface being a concave cylindrical surface. Its core feature is the ability to diverge light rays in only one direction (dimension), thereby altering the shape or size of the beam. This makes it different from spherical lenses that change light in all directions. Flat concave cylindrical lenses play an important role in various fields such as laser shaping, industrial imaging, and optical processing by one-dimensional control of light rays.

Features of Plano Concave Cylindrical Lens

The plano-concave cylindrical lens forms a divergent linear virtual image, which is used to control the size of the beam in one direction. The material of this lens is BK7, so it is not suitable for ultraviolet wavelengths.
The plano cylindrical lens is used in laser scanners, spectrometers, dye lasers, acousto-optics, optical processors, and other similar applications.
We use high-quality optical glass classical optics grinding, polishing processing techniques, surface accuracy of up to λ / 4, the finish may be 40/20. We can also be processed according to customer demand layers.
Cylindrical Lens Vs Spherical Lens: Spherical lenses are lenses taken out from a sphere such as a ball. Whereas cylindrical lenses are lenses taken out from a surface of a cylinder-like a tumbler. Cylindrical lenses have an axis associated with them. Both, spherical and cylindrical power can keep changing through life.
