Precautions for cleaning and maintenance of optical lens

Precautions for cleaning and maintenance of optical lens

The technology of optical lens is advanced, the quality is reliable, and the production cycle is short. In the cleaning process, any stickies, even nail prints or oil drops, will improve the absorption rate of the lens and reduce the service life. The addition of laser wavelength absorption to the lens will cause uneven heating and lead to the reflection of the lens. The design of the refractive index lens will change. When the laser wavelength passes through or reflects from the high absorption lens, the uneven diffusion of the laser power will make the center temperature of the lens high and the edge temperature low. This kind of change is called lens effect in optics. Tips on cleaning and maintenance of "optical lens"

Coating method on optical glass surface

Coating method on optical glass surface

Optical interference is widely used in thin film optics. The common method of optical thin film technology is coating thin film on glass substrate by means of vacuum sputtering, which is generally used to control the reflectivity and transmittance of the substrate to the incident light beam to meet different needs. In order to eliminate the reflection loss on the surface of optical parts and improve the imaging quality, one or more layers of transparent dielectric film are coated, which are called antireflective film or antireflective film. With the development of laser technology

The difference between electron microscope and optical microscope?

The difference between electron microscope and optical microscope?

Electron microscope (EM) is a large-scale instrument which uses electron beam as illumination source to image on the fluorescent screen through transmission or reflection of electron current on the sample and multi-stage amplification of electromagnetic lens. The application of electron microscope technology is based on optical microscope. Optical microscope is an optical instrument that uses visible light to illuminate and enlarge the image of small objects. Generally speaking, there are several differences between electron microscope and optical microscope

Types of optical glass - Guangda optics

Types of optical glass - Guangda optics

Optical glass is the foundation and important part of optoelectronic technology industry. Especially after the 1990s, with the continuous integration of optics, electronic information science and new material science, the application of optical glass, as the basic material of optoelectronics, in the three fields of optical transmission, optical storage and optoelectronic display, has developed rapidly, becoming one of the basic conditions for the development of social informatization, especially optoelectronic information technology. What are the different types of optical glass?

Reasons and basic coating methods of optical lens coating treatment

Reasons and basic coating methods of optical lens coating treatment

Why do optical lenses need to be coated? What is the common basic coating? 1、 Why do optical lenses need to be coated? Now many people in the glasses, will require a layer of film on the lens, this is why? Lens coating is an important index of the quality and characteristics of the lens. Different coatings have different protective effects on the eyes, greatly reducing the damage of the external environment to the eyes.
