Achromatic doublet lenses have significantly better optical performance than singlet lenses in visible imaging and laser beam manipulation applications. Achromatic Lenses are consist of two elements, usually of a positive low-index crown glass cemented to a negative high-index flint glass that have been corrected for chromatic aberration with respect to two or more selected wavelengths. We provide achromatic lenses consisting of two elements. These lenses have considerably reduced not only chromatic aberration bust also spherical aberration and coma aberration. These are designed with respect to three wavelength 480.0nm, 546.1nm and 643.8nm.
Plano-Concave Lens have one flat and one inward curved surface. PV lenses have a negative focal length and are used for image reduction or to spread light.
Double-Convex Lenses are most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.
Spherical ball lenses are widely used in optical measurement systems, projection & imaging optical systems. Also for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling.
