Meniscus lenses have one concave and one convex surface. For this lens type, the two curvatures are chosen to minimize the spherical aberration at one laser wavelength, hence meniscus lenses are used to control a laser beam of the appropriate wavelength. We offer meniscus lenses with AR coating and without AR coating. The diameter we offered is ranging from 1.5mm to 700mm, with different kinds of optical glasses.

Bi concave lenses comprise of two inward equally curved surfaces. They are ideal for beam expansion, light projection and expanding the focal length of an optical system. Bi concave lenses have a negative focal length, so the lenses are used for image reduction or to spread the light. The bi concave lenses are offered with different diameters and focal lengths. We are able to do anti-reflection coating for the lenses, including single layer AR coating, multi-layer broad band AR coating for visible wavelengths, UV wavelength and infrared wavelength. The AR coating helps to improve the transmission of the lenses greatly. We offer customized bi concave lens, so please send us drawing or specification.

Bi concave lenses have equal radius of curvature on both surfaces. The lenses are often used to expand light beams or to increase focal lengths in optical systems and devices, and biconcave lenses are also used in combination with other lenses. Among the many devices using bi concave lenses are laser beam expanders, optical character readers, viewers and projection systems. We produce bi concave lenses with different diameters and dimensions. For custom made biconcave lens, please send us drawings or specifications. Custom Made capabilities: Material N-BK7, UV fused silica, JGS1,N-SF11, Silicon, Germanium, and optical glasses Diameter available 1.5mm to 700mm Tolerance +/-0.03mm Thickness tolerance +/-0.03mm Surface quality 20/10 or better Surface accuracy Lambda/4 or better Centering 1 arc min Chamfer protective or do as per requested Coating anti reflective coating for visible, UV, infrared wavelengths.

double convex lenses comprise two convex spherical surfaces, generally with the same radius of curvature. Bi convex lenses are used as magnifiers, condensing lenses and objectives. We produce bi convex lenses with two surfaces highly polished. Applying anti reflective coating on the surfaces of bi convex lenses greatly improve its optical performance and transmission. The AR coating is available from us, including MgF2 single layer AR coating and broad band AR coating for visible, UV and infrared wavelengths. Laser standard AR coating is available from us too. For custom made double convex lenses, please send us drawings or specifications.

Plano concave lenses are flat on one side and have concave surface for another side. The lenses are designed for parallel light to be incident to the concave surface. So the plano concave lenses are used for applications including expanding beam, moderating quality image and also used for optical instruments. Because of diverging cone and virtual image, the typical use for plaon concave lens is beam expander. We produce plano concave lenses with different optical glassed such as, UV fused silica glass, N-BK7, N-BAK4, N-LAK22, Corning 7980, silicon, sapphire, etc. Anti-reflective coating and high reflection coating are available for the plano concave lenses.

Bi convex lenses have two outward curved surfaces, normally the two surfaces have same radius of curvature, with finely polished. Bi convex lenses have positive focal length, so they are used for 1:1 imaging and in multi-element systems. Bi convex lens is a good choice when the object and image are at equal or near equal distance from the lens. Bi convex lens spherical aberration is larger than that of plano convex lens, so focal length may not gather at one point. We manufacture bi convex lenses with optical flint glasses, crown glasses, UV grade fused silica glass and infrared glasses. AR coating is applied to the surfaces of bi convex lenses for enhancing transmission.

Plano convex lenses are flat on one side and with a precision convex surface on another side. Plano convex lenses are used to focus, collect and collimate the light to one point. It’s ideal choice to focus light to a single point. The lenses are useful in lasers, detectors, collimators, condensers and fiber optics. Our plano convex lenses are polished to tight tolerances minimizing wave front distortion. The lenses are offered with anti-reflection coatings for different wavelengths including visible, UV and infrared wavelengths. Competitive prices and fast delivery are available from us for the lenses. Our production capabilities: Substrate Optical glass N-BK7, N-BAK4,UV fused silica,silicon,sapphire, etc. Diameter available 1.5mm to 800mm Tolerance +/-0.02mm Focal length tolerance +/-1% Thickness tolerance +0/-0.05mm Surface quality 40-20 or better Irregularity Lambda/2 or better Centering 1 arc min or better Chamfer Protective chamfer Coating Anti-reflective coating for visible, NIR, UV and infrared wavelengths or no coating
