Lenses Uncoated, Code: 1112-051.
A Plano Concave Cylindrical Lens is a special kind of bulk optical lens component with a columnar side and a flat-concave profile contributing to a negative effective focal length (EFL). Plano concaves cylindrical lenses are versatile optical lenses for linear laser generation, one-dimensional image ratio adjustment, anamorphic beam shaping (circularization of an elliptical beam), and correction of astigmatism for laser scanners, spectroscopes, edge-emitting laser diodes, and other optical processors, etc.
These pages feature Hangzhou Shalom EO’s stocked N-BK7 Plano-Concave Cylindrical Lenses. The concave cylindrical lenses are made from fine annealed N-BK7 glass sourced from SCHOTT, and we offer a broad selection of focal lengths in stock, from -3.9mm to - 700mm, and flexible options of dimensions of the cylindrical lenses. Standard coating options include uncoated, 350-650nm, 650-1050nm, and 1050- 1580nm AR coatings. In addition, we also provide custom plano concave cylindrical made from other materials Fused Silica, CaF2, BaF2, MgF2, ZnSe, etc. with BBAR, V-coating, and MgF2 coatings.
