Optical glass is a relatively high-end product in the glass market at present. The broad optical glass of glass panel also includes colored optical glass, laser glass, quartz optical glass, radiation resistant glass, ultraviolet infrared optical glass, fiber optical glass, acousooptic glass, magneto-optical glass and photochromic glass.
In recent years, some new kinds of optical glass have been developed, such as glass with good transmittance to infrared and ultraviolet. Glass with extremely high or low refractive index or dispersion; Glass that changes color with light intensity; Electro-optic glass which produces birefringence under external electric field and so on. Intelligent switch panel optical glass can be used to manufacture lenses, prisms, mirrors and Windows in optical instruments. The components made of optical glass are the key components in optical instruments. Although not widely used by the population, the high-tech application of this glass is the most advanced of all glass products. The following is a brief introduction to the working principle of optical glass.
First of all, if only from the optical glass photosensitivity control means, there are a variety of optical glasses, through voltage, light pressure and other pressures to achieve flexible adjustment of glass brightness. The control of this optical glass is relatively simple.
Secondly, it is necessary to understand the working principle of voltage optical glass. When the control switch of the voltage optical glass is turned off, the negative ions on the glass will be dispersed, and the external light will not easily shine through the glass. Inside, the glass is opaque on the inside. When the glass switch is turned on, the liquid crystal molecules on the glass no longer work, and the whole glass will appear transparent. At this point, the glass is ordinary glass, there is no optical glass. The basic performance is missing.
The optical glass is flexibly switched between transparent and opaque states by a voltage control switch. Although the price of this optical glass is high, it can be purchased and used if you need it. It was amazing how well it worked.
