Laser protective glasses are used to reduce the intensity of potentially hazardous lasers to within the scope of safety permits. They can provide optical density exponentially attenuated light intensity for different laser wavelengths, and at the same time allow enough visible light to pass through to facilitate observation and use. CNI provides laser safety glasses with various frame styles and optical densities. For a detailed comparison of the models we offer, please refer to our laser safety glasses selection guide.
As the leading manufacturer and supplier in China, CNI is dedicated to offer best quality lasers , laser systems, High power laser, optical measuring equipment, Single longitudinal mode laser, laser processing equipment, High energy laser,machine vision and the photoelectric detection equipment.

Protective goggles selection guide
A laser filter that blocks a specific wavelength of laser light becomes safer to the eye as the transmittance becomes zero.
Optical density (OD value) expresses the degree of absorption as a logarithm.
The higher the optical density (OD value), the higher the safety.
For example, if a CW 1kW laser beam is transmitted through laser protective glasses with an OD value of 6, it will be 1mW.

Indicates the transmittance of visible light.
To the human eye, the higher the VLT value, the brighter it looks, and the lower the VLT value, the darker it looks.
