ZnSe Plano-convex Spherical Lenses are useful for a wide range of applications. PLCX series plano-convex lenses are manufactured to the exacting shanghai optics surface figure and surface quality specifications.

Standard narrowband "V"-coat and broadband "BBAR" antireflection coatings are available, see ordering section below. When used to focus a collimated beam, the light should be incident on the curved surface of the lens. Plano-convex lenses may be combined with other lenses to form complex systems.

To order an antireflection coated lens the wavelength in nanometers should be appended to the product numbe.
