PHOTOBIOMODULATION · CLASS IV
Class IV Laser Dose Calculator
Enter the treatment area, energy, target depth and your laser's settings. The calculator gives the treatment time and shows each step of the math — so you can see exactly how the dose reaches the tissue.
Treatment timeDose at depthStep-by-step math
1,200 J is the amount needed for an effect.
Centimeters below the skin. Treatment time doubles for every cm.
On continuous wave at full power, peak and average power are the same. In pulsed modes, use the average power the laser displays.

Dose through the tissue
Rule of thumb: the dose halves with each cm of depth, so the skin gets more to leave the target dose at depth.

Master photobiomodulation in the OBH Diploma
This calculator handles the math. The Orthobiological Hacker Diploma teaches the biology, the technology, and the clinical reasoning behind it — across shockwave, laser/PBM, and multi-waveform electrical modalities. Learn the full framework, earn CEUs, and bring it back to your patients with confidence.
