Optical Lenses

This vertical directory comprehensively lists the most trusted companies providing optical lenses to industry. This is an optical lenses industrial directory listing all optical lenses companies which are optical lenses manufacturers, optical lenses service companies and distributors and provide optical lenses.

Optical lenses are transparent components made from optical-quality materials and curved to optical lenses converge or optical lenses diverge transmitted rays from an object. These optical lenses rays then form a real or virtual image of the object. There are many types of optical lenses. A chromates or achromatic optical lenses consist of two or more elements, usually of crown and flint glass, which have been corrected for chromatic aberration with respect to two selected optical lenses. Aspheric optical lenses compensate for spherical aberrations and optical lenses are used primarily for their light-gathering ability. Ball optical lenses provide short focal optical lenses lengths for use with collimated light and optical lenses fiber coupling applications. Cylindrical optical lenses have at least one cylindrical surface and are used to correct or optical lenses astigmatisms. Fresnel optical lenses resemble a planoconvex or planoconcave optical lenses cut into narrow rings and flattened. If the optical lenses steps are narrow, the surface of each step is generally conical and not spherical. Gradient index (GRIN) optical lenses focus light through a precisely controlled radial variation of the optical lenses material's index of optical lenses refraction from the optical lenses axis to the edge of the optical lenses. Meniscus optical lenses can increase the numerical aperture of a positive optical lenses assembly without an undue increase in the number of optical lenses aberrations. Spherical optical lenses or singlets are transparent optical lenses components that consist of one or more optical lenses pieces of curved optical lenses glass.

Optical lenses are made from optical lenses materials that are selected for their optical lenses value and index of refraction. The optical lenses value is the constant of an optical lenses medium that describes the ratio of its refractivity to its dispersion. The index of refraction optical lenses determines the degree to which light entering a material is bent. There are two major types of optical lenses glass: crown and flint. Crown glass is harder than flint glass and has a lower optical lenses index of refraction.
