Laser safety goggles are essential safety gears for laser experiments and industrial equipment use. The choice of laser protective glasses is mainly considered from the following aspects. Wavelength, specification, laser density, light transmittance, etc.

1.Wavelength

  First, determine the laser wavelength for protection. Common laser wavelengths are: 1064nm, 10600nm, 355nm, 808nm, etc. Laser protective glasses generally provide protection within a certain wavelength band, and different wavelength combinations should be equipped with different laser protective glasses.

2.Specification

Laser protective glasses are divided into two categories: imported and domestic. According to the certification, it can be divided into products with CE certification and products without CE certification. We recommend using CE certified products.

3. laser density

According to the protection level, it can be divided into OD1+ to OD7+ level. For most applications, it is recommended to choose products with the highest protection level OD7+

4.light transmittance

 According to the workplace, laser protective glasses have requirements for light transmittance. Because laser protective glasses have a good protective effect on the laser, but also block part of the visible light. Most users want to obtain a high visible light transmittance, such as VLT>50%, which is convenient for direct observation of laser experiments or laser processing without the need for additional auxiliary light sources.

GonXing Laser provides corresponding protective glasses for different equipment.Below are the recommended safety glasses for different laser processing:

Laser marking, cutting, welding: 1064nm, OD4+, VLT 28%, CE.

CO2 laser: 10600nm, OD4+, VLT 20%, CE.

UV laser, UV laser: 190-490nm, OD4+, VLT 50%, CE.
