Plano-Concave Spherical Lens

Composed of a plane and a concave spherical surface, it has a negative focal length and negative spherical deviation, which can diverge the collimated incident light and form only a virtual image seen through the lens. Often used to expand beams, increase system length, and counteract aberrations of other lenses in the system.

Product introduction

  • Composed of a plane and a concave spherical surface, it has a negative focal length and negative spherical deviation, which can diverge the collimated incident light and form only a virtual image seen through the lens. Often used to expand beams, increase system length, and counteract aberrations of other lenses in the system. Widely used in display system projection system, laser measurement, optical imaging, beam control and other fields.
