An optical spherical lens is an optical element with a constant spherical curvature. Its front and back surfaces can be designed to be convex (curved outward), concave (dented inward), or flat. Inside the lens, the straight line connecting the center points of the two spheres is called the optical axis, and typically this optical axis passes through the physical center of the lens. Mokoptics is a professional manufacturer that provides various types of spherical lenses. Its products include but are not limited to plano-concave lenses, plano-convex lenses and achromatic lenses. These lenses are widely used in security monitoring, vehicle lens systems, digital cameras, laser technology and various optical instruments. middle.
Aspheric lenses have a radius of curvature that changes with the central axis, which can more effectively correct aberrations, especially the spherical aberration produced by spherical lenses. The design of aspheric lenses minimizes or even eliminates spherical aberration by precisely adjusting the curvature constant and aspheric coefficient, thus showing advantages over traditional spherical lenses in the field of optical imaging. The current main processes for manufacturing aspherical lenses include precision glass molding, high-precision polishing molding and hybrid molding technology.
Optical spherical lenses can be subdivided into multiple categories based on different shapes and functions, such as biconvex lenses, plano-convex lenses, biconcave lenses, plano-concave lenses, hyperhemispheric lenses, spherical lenses, meniscus lenses and cemented lenses. These lenses are made of colorless and transparent materials such as fused quartz, calcium fluoride, magnesium fluoride, silicon, germanium, zinc selenide, etc. and work according to the laws of refraction of light. Lenses can be divided into two categories as a whole: one is a convex lens that converges light, including biconvex lenses, plano-convex lenses and concave-convex lenses (that is, the convex surface is at one end and the concave surface is at the other end); the other is a concave lens that disperses light. Including biconcave lenses, plano-concave lenses and convex-concave lenses. No matter what type of lenses they are, they form real or virtual images based on the refractive properties of transparent media, playing a vital role in modern technology and daily life.
