Our lives cannot do without convex mirrors

Our lives cannot do without convex mirrors

When it comes to convex mirrors, people always think about concave convex mirrors, such as myopia mirrors, magnifying glasses, etc., which are all perspective mirrors and have different meanings from what I said today. Many people also know its purpose, for example, friends with cars know that it is a car's rearview mirror. Why can it be used as a car's rearview mirror? The reason is that it has the effect of emitting light, which allows people to see the wider and farther road conditions behind them while sitting in the car.

Optical glass and glass lens blanks

Optical glass and glass lens blanks

There is a direct relationship between the quality of glass lens blanks and molded products. Most optical glass can be used for molding. However, optical glass with a high softening point, due to its high molding temperature, slightly reacts with the mold, resulting in a short service life of the mold.

What lens is the deceleration glass made of

What lens is the deceleration glass made of

The main function of the glass is to pass through the light, and the * * * effect it can play is to make the existence of the glass exactly the same as when it did not exist. In fact, the deceleration glass does not make the movement of the external scenery look slower than it actually is, but it looks the same as the actual speed - exactly the same as when there was no glass, so the accurate name of the so-called deceleration glass should be "non acceleration glass". And other ordinary glass, relatively speaking, can be called "growth rate glass".

Precision hot pressing process for optical glass lenses

Precision hot pressing process for optical glass lenses

The precision hot pressing process for optical glass lenses is an emerging technology for producing precision optical glass components. The physical properties of glass materials can change during the hot pressing process, which can have a certain impact on the optical performance of hot pressed lenses. The company adopts the method of combining experiment and simulation research to conduct in-depth research on the change rule of refractive index and density of lens in the process of precision Thermoforming, the generation mechanism and the impact on the optical system caused by the precision thermoforming process of lens. * * * also explored the correction method of refractive index deviation of precision Thermoforming lens.

Glass lens, COB glass lens, aspherical glass lens

The issue of light distribution can be said to play a decisive role in the promotion of LED light sources, because when using LED light sources, the overall output effect, light intensity, and color temperature distribution of the light source may not necessarily meet engineering requirements. In order to make the light source meet engineering requirements, it is necessary to use the principles of physical refraction, reflection, or total reflection of light, so that the light emitted by the entire LED light source is concentrated in the desired lighting area, This process is called optical design, also known as secondary light distribution.
