Optical Glass Lens Magnifying Lens Convex Lens

Plano-convex lens, aslo called positive lens, is used to converge incident light to a spot on the axis, at a certain distance behind the lens, which is knowed as focal length. It can form both real images and virtual images(for magnifier) on the two sides. The materials to make plano-convex lens can be BK7, Fused Cilica, sapphire and CaF2 etc., for different applications.This model are commonly applied in many devices including telescopes, collimators, magnifiers,optical transceivers, condensers and other optical display or imaging optical systems. AR/NIR or other coatings are available according to the applications.

Optical Cylindrical lens
Optical Glass Plano Convex Cylindrical Lens
A Optical glass Cylinder Lenses is used to condense light in one axis.  A positive cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping.
