Optical lenses were originally used to manufacture laminated glass for cameras, which is a hard knot on ordinary glass windows or wine bottles, with a shape similar to a "crown". The name "crown laminated glass" or "crown glass" was derived from this. The laminated glass at that time was very uneven, with a lot of foam. In addition to crown glass, there is another type of flint laminated glass with higher lead content. Around 1790, French Pippi Louis Junnard discovered that mixing laminated glass sauce could produce glass with a uniform texture. In 1884, Ernst Abbe and Otto Schott of Zeiss founded Schott Glaswerke AG in Jena, Germany. In the past few years, dozens of optical lenses have been developed, including the invention of high refractive index barium crown glass as one of the key achievements of Schott Glass.
Optical lenses can change the direction of light propagation and can be used to manufacture lenses, reflectors, etc. in optical instruments. It can be divided into plastic lenses, glass lenses, and glass plastic hybrid lenses (glass plastic lenses). Unlike glass lenses, optical plastic lenses are supported by resin. In principle, an increase in quantity helps to improve the focusing ability, eliminate aberrations, thereby improving imaging quality, enhancing auxiliary functions such as zoom and stabilization. Optical lenses have evolved from 2 to 4 plastic lenses in the early stages to 6 or 7 plastic lenses.
Existing product system: Optical microscopes include biological microscopes, industrial microscopes, etc., which are indispensable specialized tools in scientific applications and daily research work. Optical components include barcode scanner lenses, planar optical components, professional imaging optical lenses, and lenses.
