Answer;

Plano-convex lens

Explanation;

  • Plano-convex lens has at least one plane surface
  • Plano-convex lenses are types of lenses that have one spherical surface and one flat surface.
  • These types of lenses are designed for infinite conjugate use or simple imaging in non-critical applications. The lenses are ideal for all-purpose focusing elements.
  • For example; they are ideal for beam expansion, light projection, or for expanding an optical system's focal length.
