CNI could offer reasonable and affordable protective goggles that protect from laser damage. The lenses are constructed to seal absorbent dyes * in rigid polycarbonate to provide excellent crack resistance and prevent subtle scratches from affecting laser protection.The optical density (OD) and LB grades of a particular wavelength range are printed on the lens or frame and cannot be erased for permanent recognition without blocking the view.

Protective goggles selection guide

• About optical density (OD value: Optical Density)

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.

• About VLT (Visible Light Transmittance)

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.
