WebFor conservative calculation, you may use the NOHD formula for a specular reflection. Determination of NHZ from the reflection of a laser: Given a 250 mW visible CW laser with a divergence of 1mrad and an incident surface spectral reflectance of 0.2, determine the range that a reflected beam is equal to the MPE. ZnUUG5I− Y WebFirst, the calculator gives the duty cycle D D, which is the product of the pulse duration T T and repetition rate f f and essentially tells how much of the time the optical power is "switched on". D = T \cdot f D = T ⋅f. Then the calculator also computes the pulse energy, which is the average power divided by repetition rate: clickplay time 2 onlineWebIrradiance: divide the power by the area of the laser spot. The spot size is usually provided by the control software, so for a round spot of 50 µm diameter, the area (πr 2) is 7854 µm 2 or 7.854 x 10 -9 m 2. To find the irradiance in this instance we compute: power / area = 0.1 × 10 6 / 7.854 × 10 -9 = 1.3 × 10 12 W/m 2. clickplay time 2
