What is Plano Convex(PCX) Lenses?
Plano-convex lenses are positive focal length elements that have one flat surface and one spherical surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optical lenses are very ideal for all-purpose focusing elements.

What is the application of Plano Convex(PCX) Lenses?
1. Beam expansion: plano convex lenses can be used to expand the diameter of the beam.
2. Imaging: plano convex lenses can be used to form clear images.
3. Beam collimation: plano convex lenses are capable of converting diverging beams into parallel beams, or converging parallel beams to a focal point.
4. Focusing collimation: plano convex lenses can be used to focus a beam of light to a precise point, or to collimate light from a point source into a parallel beam.
5. Beam collimation point source: when a plano convex lens is used to collimate a point source, the beam should be incident on a flat surface.
6. Astronomical observation:plano convex lenses can be used to make objective lenses for telescopes to help observe distant objects.
7. Military: plano convex lenses can be used for night vision equipment and laser guidance systems.
8. Transport: plano convex lenses can be used to make traffic signals and vehicle lighting systems.
9. Medical: plano convex lenses can be used to make endoscopes and microscopes to help doctors in diagnosis and surgery.
10. Arts: plano convex lenses can be used to make photographic lenses and camera lenses to capture beautiful images.

Why Plano convex lens of large focal length is used?
Plano-convex lenses are ideal for infinite conjugate systems and simple imaging tasks. They are well-suited for applications involving monochromatic
illumination and light collimation. Collimated light refers to light whose rays are parallel and spread minimally as it propagate.
