Spherical plano convex lenses of BK7 are mostly used for monochromatic lights, such as laser beams or Fraunhofer lines.
These lenses are useful when parallel beams are converged or lights from point sources are converted to parallel beams, namely at infinite conjugate ratios.
Non-coated and AR coated products are available.
