Dimension 50*8mm Improted Quartz JGS1 Laser Optical Lens window
protective glass laser cutting machine
Description:
Laser protection lens is a kind of protective lens of optical laser
lens. The main function of laser protection lens is to prevent
debris splashing and prevent splashing from damaging the lens. High
damage threshold antireflection coatings were coated on both sides
to reduce reflection. We try our best to provide all customers
around the world with the most valuable products and the best
service. At the same time, we can customize all kinds of protective
lenses. Widely used in: domestic and foreign brands - such as
Han's, Everbright, star, laser Valley, United win, Dineng, Tongfa,
Aohua, truking and other laser welding equipment, cutting
equipment.
Laser protective lens is an optical glass plate which is polished
to form two parallel surfaces. They 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. It can be
waterproof, dust-proof and scratch proof, and can be customized
according to the requirements of customers. Optical window is the
front protection piece of optical system, which can be used for the
packaging of ccd/cmos chip, the protection of optical instruments,
measuring instruments and digital equipment, various laser
equipment, cover plates on laser diodes, etc.
The basic principle of laser protection 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.
