  • Specifications

Plano-concave lenses are excellent and cost-effective choice for reduction of spherical aberrations of other positive lenses due to negative spherical aberrations sign. For best performance collimated light should incident onto the concave face of the lens. In order to achieve optimized transmission anti-reflection coatings are generally applied on to the lens input and exit surfaces.
