The "spherical curvature" of a spherical lens is constant, meaning that the front and back surfaces of the lens are part of the spherical surface, respectively. Each surface may be convex (protruding from the lens), concave (concave into the lens), or "flat" (flat). The line between the spherical centre points on the front and rear surfaces of the lens is called the optical axis of the lens. In almost all cases, the optical axis of the lens passes through the physical centre of the lens. Ecoptik (also known as BRD Optical) can provide different kinds of spherical lenses like plano concave lens, plano convex lens, achromatic lens.
The lens can be widely used in security, vehicle, digital camera, laser, optical instruments and other fields. With the continuous development of the market, lens technology is more and more widely used. Ecoptik has obtained the high technology of producing lenses. If any issues, please contact us.
The radius of curvature of the aspheric lens changes with the central axis, which has a better radius of curvature and can maintain good aberration correction. The aspheric lens is used to replace the spherical lens. The most significant advantage is that it can correct the spherical aberration caused by the spherical lens in the collimation and focusing system. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate the spherical aberration to the greatest extent. The aspheric lens basically eliminates the spherical aberration caused by the spherical lens. At present, the main processes of the aspheric lens are: precision glass molding, precision polishing molding, hybrid molding,
