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.

Sapphire wafers
These are thin slices of synthetic sapphire, commonly used as a substrate in a variety of high-tech applications. Sapphire, which is a crystalline form of aluminum oxide (Al�¢??O�¢??), is valued for its hardness, optical transparency, thermal stability, and chemical resistance. Here�¢??s a brief overview of their applications and properties:
Properties of Sapphire Wafers:
Hardness: Second only to diamond, sapphire is extremely scratch-resistant.
Optical Clarity: Transparent across a wide range of wavelengths (UV to infrared), making it ideal for optical components.
Thermal Stability: Can withstand high temperatures, which is useful in semiconductor processes.
Chemical Resistance: Highly resistant to acids and alkalis, ensuring durability in harsh environments.
Electrical Insulation: Sapphire is an excellent electrical insulator.
Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications

And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.
The plane convex cylindrical lens will focus the incident light on the line with positive focal length. It is composed of a plane and a convex cylinder. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. The flat concave cylindrical lens is composed of a plane and a concave cylinder, and its focal length is negative. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. Borisun optics provides cylindrical lenses without coating and coated with antireflection film. Antireflective film options include UV, VIS, NIR, and SWIR. Germanium, silicon or zinc selenide substrates are suitable for infrared applications, while fused quartz is suitable for ultraviolet 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.
