What is the function of the Side laser safety protection window?

The laser protective window has no selectivity to the light source, which can safely protect all kinds of diffuse reflected light; There is no selectivity for the angle of incidence of the light source, which can protect the laser and strong light of a specific band in an all-round way, the light response is fast, the attenuation rate is high, the surface is not afraid of wear, even if there is scratching, it does not affect the safety protection of light. Its optical safety performance fully meets the GJB1762-93 "Physiological Hygiene Standard for Laser Protective Glasses".

Laser glass is widely used in various types of solid-state lasers and has become the main laser material for high-power and high-energy lasers. "

The main function of the laser protective window is to protect, block and absorb the laser of a specific wavelength to achieve light safety.

There are two main materials, and the differences between them are:

Acrylic PMMA plates.

Advantages: high visible light transmittance, easy to observe by the naked eye, the protection level (optical density) is medium to high, the vast majority is OD4+, the conventional maximum size is 1000*1280 and 1005*1350, and the service life is generally 2-3 years.

Disadvantages: It does not have explosion-proof and flame-retardant effects, is brittle, is not resistant to bending, and has poor bending strength.

Polycarbonate PC board.

Advantages: It is a comprehensive and excellent amorphous thermoplastic resin, with excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance: it also has the characteristics of self-extinguishing, flame retardant, explosion-proof, etc., the hammer is not broken, the protection level is high, most of them are OD5+, OD6+, OD7+, the conventional maximum size is 1220*1820 and 1220*2440, and the service life is generally more than 5 years.

Disadvantages: Visible light transmittance is average.

For more detailed performance statements, contact professional manufacturers for explanation.
