Laser protective goggles
When choosing laser protective goggles, there are several factors to consider to ensure proper protection. Here are the three key factors:
-
Wavelength of the laser:
The goggles should be designed to protect against the specific wavelength of the laser radiation. Lasers emit light in different ranges (e.g., visible light, infrared, or ultraviolet). Protective goggles should filter the specific range that the laser operates in. For example, for lasers with a wavelength of 532 nm (green light), goggles specifically protecting against this range are needed. -
Optical Density (OD):
Optical density indicates the goggles' ability to block laser radiation. The higher the OD value, the stronger the protection against the laser. For example, high-powered lasers require a higher OD to prevent eye damage. -
Type of laser radiation and its power:
Different types of lasers (e.g., pulsed or continuous emission) require different protection characteristics. It is also important to consider the power of the laser, as high-powered lasers require protection with a higher OD. Goggles should be selected based on these factors to ensure complete safety.
These three criteria will help you choose the right protective goggles depending on the type of laser and operating conditions.
