With the rapid development of modern science and technology, laser technology has been widely used in many fields such as industrial manufacturing, medical cosmetology, scientific research and experiments. Especially when using 1064nm wavelength lasers, in order to protect the operator's eyes from laser radiation, laser protection plates have become an indispensable safety device. However, the 1064nm laser protection plates on the market come in many different colors. What is the reason for this?
1064nm laser protection plates will have different colors, which is mainly due to the different material selection, coating process and protection level. The following is a related introduction to these reasons:
1. The impact of material selection
Acrylic PMMA plate: This material has a high visible light transmittance, which is easy to observe with the naked eye, but has poor bending strength and is prone to brittle cracking.
Polycarbonate PC plate: This material has excellent electrical insulation, elongation and dimensional stability. It also has the characteristics of self-extinguishing, flame retardant, explosion-proof, etc. It cannot be broken by hammers, has a high protection level, and its service life generally exceeds 5 years.
2. Differences in coating processes
Absorption laser protection plate: This plate can effectively absorb 1064nm lasers and reduce reflection and scattering by adding light absorption materials of specific wavelengths to the substrate.
Reflective laser protection plate: This plate reflects the laser through optical glass or special coatings to avoid laser penetration, and is suitable for the protection of high-power lasers.
3. Different protection levels
OD value: The higher the OD value, the stronger the protection ability of the protection plate. For example, a protective plate of OD4+ can provide basic 1064nm laser protection, while protective plates of OD5+ and OD6+ provide a higher level of protection.
Visible light transmittance: Protective plates of different colors may have different visible light transmittances, which affects the user's visual experience and operating convenience when using the protective plate.
4. Differences in application scenarios
Industrial applications: In industrial applications such as laser cutting and welding, high-grade protective plates are usually required to protect operators from laser damage.
Medical cosmetology: In the field of medical cosmetology, the laser protective plates used need to be able to effectively protect the laser and ensure sufficient visible light transmittance so that doctors can operate accurately.
5. Diversity of product models
Different models: There are many models of laser protective plates on the market, such as XL-2 dark blue, XL-3 orange-red, XL-4 turquoise, etc. Each model has its specific protection band and applicable scenarios.
Customization service: Some manufacturers provide customization services and can make laser protective plates of specific colors and sizes according to the specific needs of customers.
6. Compliance with safety standards
International certification: Many laser protection panels have passed international safety standards certification, such as CE certification, ensuring the quality and safety of the product.
Technical parameters: The technical parameters of the product, such as laser attenuation multiples, visible light transmittance, etc., are also one of the factors affecting color selection.
7. Consideration of user experience
Comfort: Protection panels of different colors may affect the user's visual comfort. Choosing the right color can reduce eye fatigue.
Aesthetics: In some applications, the appearance color of the protection panel is also part of the design considerations to meet the needs of aesthetics.
In summary, the reason why 1064nm laser protection panels have different colors is due to the combined effect of these factors. When choosing a laser protection panel, these factors should be considered comprehensively to ensure that both the needs of safety protection are met and a good user experience is provided.
