Laser Power Density Calculation Form

LASER POWER DENSITY CALCULATION FORM

In order to provide you with the correct protection for your laser environment, it is important to know what the irradiance/intensity of your laser is. If you do not know how to calculate the irradiance of your laser, we would be happy to assist. Please fill out the information below and a barrier specialist will contact you.

The laser barrier hazard analysis concepts outlined below are based upon Section 4.4.2.5, Laser Protective Barriers and Curtains, (Class 3B or Class 4), Appendix Section B8.2, and Appendix Section D3.4 in the ANSI Z136.1-2014 National Standard.
