These plano-convex cylindrical lenses are derived from doric™ gradient-index cylindrical lenses by grinding and polishing. Compared to its parent lens, half-doric lens has longer focal length, longer working distance and a 0.35 NA.
They can be used in the visible and near infra-red spectrum as fast-axis collimators for single laser diodes or for building cylindrical lens arrays for laser diode bars. The absence of acylindrical surfaces makes the alignment of plano-convex cylindrical lenses simple and fast.
In order to accommodate a small emitter pitch, the edge of the lens may be ground to a desired width and the initial rod diameter could be trimmed to a smaller height as well.CONTACT US
