Ball lenses are highly polished spheres made of optically transparent homogeneous materials. Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller sphere has the benefit of fitting into smaller packages.

Condenser lenses concentrate light into a projected beam. Used in projectors, enlargers, spotlights, and photo cell systems, they are usually mounted in pairs so that their convex surfaces are nearly in contact.

We specialized in the production of various convex/concave Lens of Optical glass, magnifying glass, telescope Lens, spotlight Lens, and Optical coating products, such as Optical components for projecting camera, traditional camera, digital camera, photography equipment, mobile phone, bar code machine l and monitoring device. Meantime, we have many sets pricise CNC glass cutter, we can cut glass for you(including round, special-shaped and special small size), the precision can be +/-0.05.

A Lens having two spherically curved faces, one convex and the other concave, so that it has the form of a shell. A positive meniscus Lens is thicker in the middle than at the edges and serves as a converging Lens; a negative meniscus Lens thickens toward the edges and works as a diverging Lens. Very large telescopes may use meniscus mirrors, which are lightweight and require an active control system to retain their shape against gravity.

Micro lenses are small lenses, generally with diameters less than a millimetre (mm) and often as small as 10 micrometres (μm). The small sizes of the lenses mean that a simple design can give good Optical quality but sometimes unwanted effects arise due to Optical diffraction at the small features.

Achromatic lenses are doublet systems consisting of one crown and one flint element, cemented together along a matching curvature, so that white light coming into the Lens is all focused (imaged) at the same point on the other side of the Lens. They are designed to minimize spherical and chromatic aberrations for infinite conjugate, visible spectrum imaging applications. When used on-axis, an achromatic Lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction. This performance can be achieved over a broadband of wavelength. Achromatic lenses can be used to collimate and focus laser beams. They can also be used for high-quality imaging on-axis. However, the off-axis performance is significantly worse than the on-axis performance. If your...
