Description of Laser Protective Lens :

Laser protection lens is mainly used in laser cutting and welding machine to block or prevent high-temperature spatter from damaging the valuable laser focusing lens, but it can not reduce the laser output energy. As a final optical part, it is placed in the work area to protect the high-value internal parts. It is applied to the laser head of laser cutting and welding machine.

Laser protective lens is an optical glass plate which is polished to form two parallel surfaces. Laser Protective Lens can be used as protection elements in a variety of complex environments, and their high efficiency of transmittance makes them have little influence on the visible light passing through. The common coating is anti reflection film (AR) and scratch proof film (as), which can also improve the effect according to the needs of customers. 

Parameter of Laser Protective Lens

Application of Laser Protective Lens

In order to protect the focusing lens, a laser protection lens is designed. For this reason, the cost of laser equipment in the processing process is saved, and it is widely used.

The basic principle of Laser Protective Lens detection

The impurities in the laser protection lens must be different from those in the optical window. When light is incident to the optical window, the reflection and refraction of various impurities are different from those around the optical window. For example, when the uniform light is perpendicular to the optical window, for example, there is no impurity in the optical window, the direction of emission will not change, and the detected light is even; When there is impurity in the optical window, the emitted light will change the detected image accordingly. Due to the presence of impurities, stress concentration and deformation occur around them, and it is easy to observe in the image. If light transmission defects (such as cracks, bubbles, etc.) are encountered, the light will be refracted at the defect and the intensity of light is greater than that around, so the light detected on the camera target will be enhanced accordingly; If there is any impurity in the light absorbing type (such as sand), the light position at the defect will be weakened, and the light detected on the camera target will be weaker than the surrounding. Through analyzing the intensity and characteristics of the image signal collected by the camera, the corresponding defect information is obtained.

Advantage of Laser Protective Lens :

The imported coating machine is used to plate the hard mold, with high adhesion, super high temperature resistance, high transmittance, high laser damage threshold, low residual reflection and long service life
