High-Quality Aspheric Cylindrical Glass Lens Perfect for Precision Optics

Product Description

Aspheric cylindrical lens are usually semi-cylindrical. Compared with lens, cylindrical lens converge or diverge the incident light along the focal line instead of the focal point, which is widely used in many industries and fields such as optical instruments, photographic equipment, optical communication, medical imaging, laser processing and so on. It combines the advantages of aspherical lens and cylindrical lens, and provides a powerful tool for optical designers to optimize the performance of optical system, reduce aberration and improve imaging quality. Its optical performance is related to materials. Glass aspherical cylindrical lens is widely used in optical systems and medical equipment because of its excellent optical performance and durability.

Features

(1) Aspheric design

Aspheric design of aspherical cylindrical lens is helpful to reduce aberration, especially spherical aberration and astigmatism, thus providing clearer imaging effect.

(2) Unidirectional focusing

Due to its cylindrical characteristics, this lens can focus or diffuse light in one direction, while in another dimension perpendicular to this direction, the light propagation is almost unaffected.

(3) High light transmittance

The glass material has high light transmittance to ensure the effective transmission of light energy.

(4) Durability

Glass materials are usually durable and suitable for long-term use.

(5) Highly customized

Aspheric cylindrical lens can be customized according to the requirements of specific applications, including its size, curvature, aspheric coefficient and coating.

(6) Improving the system performance

The use of this lens can significantly improve the performance of the optical system without increasing the system complexity.

Advantages

(1) Reducing aberration

The spherical aberration and other aberrations in the optical system are effectively reduced through aspheric design.

(2) High-precision focusing

It can achieve high-precision light focusing in one direction, which is suitable for applications that need fine beam control.

(3) Improving system efficiency

The overall performance and efficiency of the optical system are improved without adding additional optical elements.

(4) Customization flexibility

It can be highly customized according to specific application requirements to meet different optical design requirements.
