The SI unit of radiant exposure is the joule per square metre (J/m 2), while that of spectral exposure in frequency is the joule per square metre per hertz (J⋅m −2 ⋅Hz −1) and that of spectral exposure in wavelength is the joule per square metre per metre (J/m 3)—commonly the joule per square metre per nanometre (J⋅m −2 ⋅nm −1).

To convert J (energy) to J/cm 2 (specific energy), divide the energy absorbed by the area (in cm 2) of the un-notched ligament, i.e. by ( (W-0.2)xB)cm 2. For example, if the energy absorbed during testing of a full-size specimen is 100J, then the specific energy is 125J/cm 2.

In general physics, the fluence is defined as the time-integrated flux of some radiation or particle stream. Specifically in optics, the fluence F e.g. of a laser pulse is the optical energy delivered per unit area. Its most common units are J / cm 2 (joules per square centimeter).

Oct 21, 2019 · The energy unit of light intensity is generally expressed by J/m2 and mJ/cm2, that is, the light energy per unit area. The UV energy units and UV light intensity units conversation and how to convert between UV energy units and UV light intensity measurement units will be introduced in this paper.

Nov 12, 2015 · If you know the power output of your laser in watts and the (effective) spot size of the beam then from the desired J/cm2 you can calculate how many secons/minutes you will need to keep the target illuminated to deliver so many J per cm2.

If the laser beam is being scanned across a surface area, the AVERAGE Fluence over the area is, H(av)(J/cm2) = Laser Power (W)/Scanned Area (in cm2) X Pulse Duration (sec) X Total # of...

Boundary Energy can be set at 5.0 J/cm 2 for bare skin or at the rating of any proposed PPE. The limit of 5.0 J/cm 2 is that at which a person is likely to receive second degree burns. For a more detailed explanation of the calculation, please see: Arc Flash Calculations Post. Electrical engineering education and community.
