How to pay attention to the daily use of laser lens?
Lenses are generally divided into two types, one is a single-light lens and the other is a double-light lens. Convex lens plays a convergent role in light rays, which is called convergent lens "; Concave lens plays a divergent role in light rays, which is called divergent lens". A single convex lens can form a real or virtual image, but a single concave lens can only form a virtual image. Laser headlight lenses were only introduced in the car lamp modification market, but the status of laser headlights is much higher than that of xenon lamp lenses and LED lenses. Laser headlights are in a leading position in terms of brightness and lighting effects., So how should I pay attention to the daily use of laser lenses?

What is the standard of lens inspection?
The lens is made according to the law of light refraction. It is a refractor and an optical element made of transparent materials (such as glass, crystal, etc.).) The image made of lens includes real image and virtual image, which can be generally divided into two categories: convex lens and concave lens. The center part is thicker than the edge part, which is called convex lens, and there are three kinds of convex, plano-convex and concave-convex. The center part is thinner than the edge part is called concave lens, and there are three kinds of double concave, plano-concave and convex concave. So what is the test standard of lens? Let's introduce it to you.

What are the types of optical lens head mirror?
Optical lens is a spherical optical element made of transparent materials (glass, crystal, etc.) according to the law of light refraction, which can improve the utilization efficiency and luminous efficiency of light. Nowadays, optical lens is more and more widely used. According to the actual application requirements, optical design and modeling are used, and molding molds are manufactured, and suitable lenses are obtained through injection molding. So what are the types of optical lens head mirror? The following small series to introduce.

What are the factors associated with optical lens resolution?
An optical lens is an optical element made of transparent material and is an independently assembled part. It includes a lens barrel (including an aperture), a lens, a spacer, a stopper and other structures. The more mature technology of optical lens manufacturers is the single substrate coating process, that is, the use of glass, crystal, PC or resin and other materials, through the optical technology to make the lens substrate, and then use the coating process to coat the surface, with wear resistance, anti-fouling, anti-ultraviolet, anti-radiation, anti-blue, anti-glare and other functions. So what are the factors related to the resolution of the optical lens?

Surface defects of optical components
Surface defects of optical components, often referred to as "surface finish" or "surface defects", are indicators that describe the number and size of pitting, scratches, and edges allowed on a polished surface. In the imaging optical system, the quality of the component surface directly determines the imaging performance of the system, in the field of strong laser and semiconductor applications, when the component surface quality is not good, it will lead to the situation that the optical system can not be used, therefore, it is very necessary to clarify the definition and determination method of the component surface defect. However, in practice, there are many standards for determining surface defects, and the definitions of each standard are not uniform, which brings some confusion to the actual work of optical practitioners. In view of this situation, this paper from the 1185-1974 old national standard, the United States military standard and the new national standard with reference to ISO 10110 three standards, introduces their specific content, as well as the approximate correspondence between each other, so as to help you in the actual work can better identify and control the surface defect index of the component.

Laser lens direct good or good reflection?
Laser lenses are generally divided into two categories, which are commonly known as reflective and direct laser lenses. The reflective type uses a blue laser head to hit the laser on the high beam led phosphor to emit light, which enhances the high beam. There is a direct laser lens, but the so-called direct laser lens laser module also needs to be divided into two categories, one is a transmissive laser head, and the other is a reflective laser head. Transmission type laser head, is the laser emits white light through the luminous body, the volume is small, but the white laser head spot has yellow halo. Reflective laser head, is the laser head light to the molybdenum reflective lens, the laser is reflected to the phosphor, the relative volume is large, but the spot is perfect. So the laser lens direct good or reflection good? The following small series to introduce to you.
