Double concave cylindrical lenses

Double Concave Cylindrical Lenses, as indicated by the name, is a special cylindrical lenses with two concave surfaces. Usually the two concave surfaces do not have the same x and y axis thus it can be used to change the aspect ratio of the image. It is also used to expand the income light in laser applications.

Double concave lenses are utilized in collimators to create a parallel beam of light for alignment purposes. The lenses help in generating a diverging light beam, which can be precisely controlled and used to calibrate and align other optical instruments such as lasers, spectrometers, and interferometers.

Nova offers Double concave cylindrical lenses from various materials such as fused silica, BK7, optical glass, BaF2, CaF2, MgF2,LaF3, LiF ,Zns and ZnSe with circular or rectangular dimensions or other custom modules. Coating options include: uncoated, MgF2 single layer, V-type, broad band AR coating or customized.
