1. Strict dimension Control, Process various specifications and different radii Cylindrical Lens according to the drawings.
2. Options of material: Optical Glasses，Laser Crystal，Fused Silica，Radiation Resistant Glasses，IR & UV Materials，Metal Materials.

Meniscus Cylindrical Lenses convert the transmitted plane wave into a cylindrical wave or converts the cylindrical wave into a plane wave or a Spherical wave. This lens corrects the visual Aberration. Meniscus Cylindrical Lenses can be used in Projection System, Imaging System, Optical Instrument, Laser Measuring System. Boxin selects the preferred material, process and Coating in according to customers’ requirement.
