Lens Quartz Glass Plano-Convex Lens Laser Optical Lens Optical Components

Plano-convex lenses can focus collimated beams onto the back focal point and also convert point light sources into collimated beams. Plano-convex lenses are typically made of K9 glass,

with their anti-reflection coatings designed for the wavelength range of 400–700 nm. Some are also manufactured using ultraviolet quartz as the base material. When ultraviolet quartz is used as the substrate,

they exhibit high transmittance in the ultraviolet region and a low thermal expansion coefficient, and can be coated with ultraviolet AR coatings for use in specific applications.
