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.
