Product Details

Plano concave lenses are mainly used for infinite conjugate applications, laser applications, image systems. with the negative focal length, plano concave lenses have a flat face and an concave face.

A plano-concave lens is machined from a plane and a concave sphere.It has a negative focal length, which makes it widely used.In optical system, it is used for beam expansion, projection ray and extension of optical system focal length.Plane-concave lenses can diverge a collimating beam into a virtual focus and are commonly used in Galilean beam extenders. Plane-concave lenses have negative focal length and negative spherical aberration and can be used to offset the aberration of other lenses in the system.H-K9L plano-concave lenses are often used to diverge parallel light and have excellent transmittance from visible to near infrared (350-2000nm), which are widely used in telescopes, lasers and other fields.For optical divergence, if the absolute magnification is less than 0.2 or greater than 5, it is best to choose a plano-concave lens. If it's between these two values, it favors a biconcave lens.In order to reduce spherical aberration, parallel light should be incident on the surface of the plano-concave lens Customer can Choose a variety of coatings.

Sunday is manufacturing plano concave lenses with glass, fused silica, infrared crystal, sapphire materials. with the advance testing machines Sunday can make high precision lenses for customers.
