Cylindrical lenses are a special type of lens with a curved surface in one direction and a flat surface in the other. This design endows cylindrical lenses with unique optical properties and applications. Here is an explanation of the functions and applications of cylindrical lenses, along with links to related image resources.

Functional Application Description:

• Altering Image Size: Cylindrical lenses can change the size of the image. For example, they can convert a point light source into a line light source or change the height of the image without altering its width.

• Linear Detector Illumination: In barcode scanning and linear detector illumination, cylindrical lenses are used to focus light, allowing the detector to more accurately identify barcodes or other linear patterns.

• Holographic Illumination and Optical Information Processing: Cylindrical lenses are also used in holographic illumination and optical information processing. They help form specific light spot shapes to meet the design requirements of particular optical systems.

• Laser Systems: In laser emission and laser scanning, cylindrical lenses can be used to shape the laser beam, achieving one-axis focusing or divergence, and optimizing the performance of the laser.

• Stereoscopic Display Technology: Cylindrical lenses have important applications in stereoscopic display technology. They refract and focus light to different points to achieve a multi-viewpoint three-dimensional display effect.

• Optical Measurement and Spectroscopy: Cylindrical lenses are widely used in optical measurement and spectroscopy. They can adjust the width and direction of the light beam to meet the needs of different measurements and analyses.
