Product Case Studies

The typical application of plano convex cylindrical lenses is to shape deformed light beams using a pair of cylindrical lenses. A pair of plano convex cylindrical lenses can be used for collimating and circularizing the output of laser diodes. Another possible application is to use a single cylindrical lens to focus the diverging beam onto the detector array.

In order to minimize spherical aberration, when converging a collimated beam into a line, the collimated light should be incident from the curved surface of the lens, while when using a collimated light source, the line light source should be incident on the plane of the lens.

Main characteristics

• Asymmetric focusing：A plano convex cylindrical lens can focus light in one direction (the curvature direction of the cylinder), while the propagation of light in the vertical direction is not affected.
• Linear focusing：The focal point formed by a lens focusing light is not a point, but a line, which is very useful for applications that require linear light sources.
• Customized design：According to specific application requirements, different curvatures and sizes of plano convex cylindrical lenses can be designed to achieve the expected optical effects.

application area

The unique optical properties of plano convex cylindrical lenses make them widely used in multiple fields:

• LASER SYSTEM：Used to adjust the shape of laser beams, convert circular laser beams into linear laser beams, for laser cutting, laser marking, etc.
• Optical scanning：Used in barcode scanners and other optical scanning devices to generate linear beams and improve scanning efficiency.
• DESIGN：In specific lighting applications, it is used to create light spots of specific shapes, such as linear lighting.
• Optical Testing and Measurement：In optical measurement equipment, it is used to focus or diffuse light to obtain the desired testing or measurement effect.

advantage

• High precision focusing：Capable of accurately focusing light on a single line, suitable for applications that require high control over light.
• flexibility：By changing the parameters of the lens, such as curvature, material, and size, various optical effects can be achieved to meet different application requirements.
• Simplify the design of optical systems：The use of plano convex cylindrical lenses can simplify the design of some optical systems and reduce the number of optical components required.

note

When using a plano convex cylindrical lens, the following points need to be considered:

• Material selection：Select appropriate lens materials based on the spectral range of the application to ensure good light transmission performance.
• perfect alignment：Due to its asymmetric focusing characteristics, plano convex cylindrical lenses require precise alignment during installation and use to ensure the desired optical effect is achieved.
• Wear resistant treatment：Considering that some applications may come into contact with harsh environments, choosing or customizing lenses with wear-resistant and anti pollution surface treatments can extend their service life.

In summary, the plano convex cylindrical lens is a powerful optical component that, through its unique design and application, can achieve efficient and precise light control and management in various fields.
