Like all Plano-Concave Cylinder lenses, these lenses have a negative focal length, often used to focus parallel or divergent beams onto a line or to change the aspect ratio of an image
N-bk7 Plano-Concave Lenses can also be coated with AR Coating
- -A: AR@400-700nm,
- -B: AR@650-1050nm,
- -C: AR@1000-1650nm,
anti-reflection coating can reduce the reflectivity of each surface of the lens.

VIS AR-Coating 400-700nm

NIR AR-Coating 650-1050nm
