Elements
Plano Convex Lens
Plano-convex lenses are positive focal length elements that have one spherical surface and one flat surface. They can be used to focus, collect and collimate light. These optic lenses are ideal for all-purpose focusing elements. It Converges the incident light. Form both real and virtual image
Biconvex Lens
Biconvex lens have positive focal lengths. It form both real and virtual images. These lenses are used as magnifying or condensing lenses. They are also used as objectives or magnifiers. These are utilized in many imaging systems such as the telescopes, monocular, microscopes, binoculars, cameras, projectors, etc.
Achromatic Doublet
Achromatic lenses are ideal for a range of applications including fluorescence microscopy, image relay, inspection, and spectroscopy and widely used in a multi-lens optical system that usually consists of several achromatic lenses. Also used in high-quality microscopes ,telescopes and photographic apparatuses are complex lens systems that can eliminate both hyper chromatic and other monochromatic aberrations.
Ball Lens
Ball lenses are widely used for focusing and coupling light in and out of fibres. BK7 ball lenses are perfect for visible applications from 350nm through the near infrared. Ball Lenses made out of UV Grade Fused silica have good UV and IR transmission from 185nm up to 2000 nm. BK7 ball lenses are very economical and available in large quality. We manufacture Glass Ball Lenses in sizes ranging from 3mm to 25 mm in diameter.
Half Ball Lens
Half ball lenses are commonly used to improve signal coupling between Emitters, Fibres, laser collimating device, Transmitters, Receivers and Detectors. It has a shorter focal length
