K9 Plano concave cylindrical lens


  • K9 plano concave cylindrical lens only diverges in one direction and has no divergence function in the other direction
  • K9 plano concave cylindrical lens can see the transmittance of near infrared (350-2000nm).
  • Cylindrical plano concave lens is a lens with concave curvature in the vertical direction and no curvature in the horizontal direction. It is combined with cylindrical flat convex lens to shape the elliptical beam of semiconductor laser into a circle, etc
