The law of reflection can be regarded as a special case of the law of refraction when n=-n’. Therefore, in the formula for the refractive

The beauty instrument photon rejuvenation technology uses discontinuous intense pulsed light (IPL), which the beauty instrument filters out harmful short wave light (UV) through specific

We know that the filter can reach the parameters required by the design, mainly by using the optical interference principle. The realization of the optical

Ion assisted deposition (AD) technology has been widely used as a process to improve the properties of optical filters films. Years of practical research have

The optical components of the filter and optical lenses are made of light glass. Common optical glass can pass light with a wavelength of 0.35m

At present, lasers have many applications in modern manufacturing. The output power range of lasers ranges from tens of watts to hundreds of kilowatts, which

Ultraviolet Filter for Water Quality Analysis in the Principle of Total Nitrogen Online Analyzer- In order to protect the water environment, it is necessary to

220nm, 275nm UV filter- With the rapid development of China’s economic level, the pollution problem of domestic and industrial wastewater has gradually worsened. According to

The infrared cut-off filters can effectively block the infrared light that interferes with the imaging quality and maintain high transmittance of visible light, making the
