What is Plano Convex Lens?

  • A plano-convex lens is a positive focal length element that has one spherical surface and one flat surface.
  • It is designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications.
  • It can be used to focus, collect and collimate light with minimal spherical aberration.

Specifications for Plano Convex Lenses

  • Diameter: The physical size of the lens, usually measured in millimeters (mm).
  • Focal Length: The distance from the principal plane of the lens to the image plane, usually measured in millimeters (mm).
  • Center Thickness: The distance from the primary principal plane location to the end of the element, usually measured in millimeters (mm).
  • Radius of Curvature: The directed distance from the vertex of a surface to the center of curvature, usually measured in millimeters (mm).
  • Substrate: The material of the lens, such as glass, plastic, or crystal.

Coatings for Plano Convex Lenses

  • Anti-reflection coatings are used to reduce the reflectance of light from the lens surface and increase the transmission efficiency.
  • Different coatings are optimized for different wavelength ranges and angles of incidence.

Applications of Plano Convex Lenses

Plano-convex lenses are versatile and can be used in various optical systems and devices.

Some examples of applications of plano-convex lenses in laser applications are:

  • Laser beam collimation: A plano-convex lens can be used to collimate a divergent laser beam by placing the convex surface towards the source and adjusting the distance to match the focal length.
  • Laser beam focusing: A plano-convex lens can be used to focus a collimated laser beam to a spot by placing the flat surface towards the source and adjusting the distance to match the focal length.
  • Laser beam expanding: A pair of plano-convex lenses can be used to expand or reduce a laser beam by placing them with their convex surfaces facing each other and adjusting the separation distance.
  • Laser diode correction: A plano-convex lens can be used to correct the astigmatism of a laser diode by placing it close to the source and orienting it at an angle.
