Dosage calculator
Estimate light exposure and session time
This calculator converts irradiance and target fluence into estimated session time. It is a planning tool, not a treatment prescription.
This estimates light exposure from reported irradiance. It is not medical advice, a treatment recommendation, or a guarantee of outcome.
Estimated session time
1.7 minutes to reach 5.0 J/cm2 at 50 mW/cm2.
Formula: seconds = target J/cm2 / (mW/cm2 / 1000). Distance is recorded for context; v1 does not estimate beam spread or distance falloff unless device-specific data is available.
