Specification for the use of laser protective glasses
Laser protective glasses, also known as laser glasses or laser protective glasses, are indispensable safety protectors for laser research and development, various laser experiments and the use of industrial laser equipment.
There are many types of laser goggles, with different materials, different principles, and different applications. So, what are the specifications for the use of laser protective glasses?
Specification for the use of laser protective glasses:
First, determine the laser wavelength for protection. Common laser wavelengths are 1064nm, 10600nm, 355nm, 808nm and so on. Laser protective glasses can generally provide protection in a certain wavelength band, and different laser protective glasses should be configured for different wavelength combinations. For example, for the most commonly used wavelength combination of 1064nm and 10600nm for laser processing, you can choose FG1 to protect both laser wavelengths at the same time. For example, the combination of 1064nm double frequency and triple frequency 355nm and 532nm, we can choose ARG laser The goggles protect both lasers. Wilkes Optoelectronics has very rich experience in model selection, which can help customers quickly determine the required model.
Secondly, it is to determine which grade of laser protective glasses to choose. Laser protective glasses are roughly divided into two categories: imported and domestic. According to the certification, it can be divided into CE certified and non-certified products, and according to the protection level, it can be divided into OD1 + to OD7 + levels. For most applications, we recommend the use of products with CE certification, and recommend the selection of the highest protection level OD7 + products. Of course, for some ultrafast lasers, such as fs lasers, we also need to refer to more parameters about the protection level.
Thirdly, the visible light transmittance requirements of laser protective glasses need to be put forward according to the working situation. Because the laser goggles have a good protective effect on the laser, but they also block part of the visible light. Most users want to obtain higher visible light transmittance, such as VLT> 50%, which is convenient for direct observation of laser experiment imaging or laser processing without adding additional auxiliary light sources; there are also a few users that require lower visible light transmittance, such In some cases where the visible light is too strong, it is recommended to use the model with a transmission rate of <50% or even <30% to achieve the best effect of protecting the eyes.
In short, the use of laser protective glasses needs to consider factors such as laser wavelength, protection level (grade), light transmittance (work place), etc. Through this set of procedures, users of laser protective glasses can be effectively protected while also having Good user experience.
