Bi-concave Spherical Lenses

Bi-concave Spherical Lenses

Bi-Concave Lenses, or, “Equi-Concave Lenses”, are used to expand light, or, diverge a collimated beam and produce a negative focal length. Choose from either N-BK7 or Fused Silica in this section and one of our standard broadband AR coatings. We also offer numerous alternative AR coatings, suitable for a variety of laser wavelengths. Can’t find what you need? Ask us to modify a stock lens for quick delivery, or, send us requirements for a complete custom solution.
