Check your laser specifications
When choosing your laser safety glasses, pay careful attention to the laser products specifications. It is best done by consulting the laser operating manual or/and a product expert.
- Wavelength which is usually specified in nm (nanometers - 10-9m) or µm (micrometers - 10-6m)
- Laser classification which is referred to as Class 1 (I), Class 2(II), Class 2M, Class 3(III), Class 3B (IIIB), Class 3R, Class 4 (IV)
- Other specifications depend if it is a pulsed or continuous (CW) laser.
- Continuous laser: For continuous lasers, the power is typically specified in mW (milliWatts - 10-3W), W(Watts) or kW(kilowatts - 103W)
- Pulsed laser: If it is a pulsed laser then the pulse energy which is specified in Joules, pulse length in us (microseconds – 10-6s), ns (nanoseconds - 10-9s), ps (picoseconds - 10-12s) or fs (femtoseconds - 10-15s).
Take time to carefully read the operating manual before selecting the appropriate eye protection.
Picking the appropriate pair of safety glasses requires a solid understanding of the standards, specifications and the product itself – consult a product specialist if your unsure.
