Plano convex cylindrical lens

What Is a Plano Convex Cylindrical Lens?

A plano convex cylindrical lens (PCCL) is a one-axis optical cylindrical lens with two distinct surfaces: one flat (plano) and one curved in a cylindrical shape (convex).

Its curvature is limited to a single plane , while the perpendicular axis remains flat.

This unique geometry enables it to focus, collimate.

Or shape light exclusively along the curvature axis—leaving light propagation unchanged in the perpendicular direction.

• Custom substrate materials like N-BK7, Fused Silica
• Ideal for circularization of laser diode output, laser line generation, and image aspect ratio modulation
• Applications: Laser scanners, diode lasers, optical metrologies, and spectroscopes

Advantages of the lens

• One-dimensional light manipulation

The cylindrical convex surface acts as a “single-axis focusing tool”.

It can converge parallel light rays into a thin line, or converge divergent light rays from a point source into a parallel beam.

This makes it highly suitable for applications requiring a linear light distribution.

• Low aberration and high efficiency

It can be directly installed on the optical support and reduces assembly errors.

• Suitable for most harsh situations

By using different coatings, it can adapt to various environments.

Applications:

The lens can be used in different situations. Here are the main using situations:

• Laser Processing Industry

Laser Cutting/Welding，Laser Marking/Engraving，Laser Heat Treatment

• Machine Vision & Imaging

Line Scan Camera，Barcode/QR Code Scanners，Microscopy

• Medical & Biomedical Equipment

Ophthalmic Instruments，Laser Therapy Devices，Biomedical Imaging

• Consumer Electronics & Automotive

3D Printers，Automotive Sensors
