Product Description General Introduction:Meniscus lenses are concave-convex lenses. The lens has an outer convex mirror and an inner concave mirror. If the outer convex radian is greater than the inner concave radian, the lens has a positive focal length and is used as a magnifying glass; If the concave side curvature is large and the convex side curvature is small, it is a negative meniscus lens. Negative meniscus lens can be used to replace other negative lenses. Meniscus lenses are used to reduce spherical aberration to a large extent, and can obtain smaller focus and less aberration than plano-convex lenses to improve image quality. When combined with another lens, a meniscus can shorten the focal length and thus increase the numerical aperture (NA) of the system without introducing significant spherical aberration. For convergent collimating light, the convex surface of the lens should face the light source.Main Applying:1).Projector2).Laser scanner3).Spectrophotometer4).High power laser resonator5).Long distance off-line interferometer and other high-precision testing instruments and devices6).In the typical application of cylindrical mirror, a pair of cylindrical mirrors is used to shape the deformed beam7).A pair of positive cylindrical mirrors can be used to collimate and round the output of laser diode. It is an ideal element to change point light source into line light source8).Laser level9).Barcode scanner10).Array CCD concentrator11).Illumination in linear detector12).Holographic illumination13).Optical information processing14).Laser emission15).Optical cylindrical mirrors are also widely used in high power laser systems and synchrotron radiation beamlinesMain Cooperation Materials Manufacturers: CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,C-LASER,J-FIBER,ETCMain Export Countries & Areas: Usa, Uk, Japan, Germany, Spain, France, Swiss, Korea, Russia, Pakistan, India, Portugal, Canada, New Zealand, Australia, Saudi Arab, Turkey, Finland, Poland ,etc.Raytekoptics Extra value added services offered:1).
