Rev 2 hardware is in fabrication. Here’s where things stand. Background The Rejuv is a handheld red and near-infrared light therapy device designed around a specific principle: that delivered dose — measured in J/cm² at the treatment surface — should be known, not estimated. Every unit is individually calibrated using a NIST-traceable optical power meter […]

1. Why measurement matters When evaluating a photonic device, the quantity of interest is the optical power delivered per unit area. As the LEDs are spread out, so too is the energy. Because the LEDs are distributed across a surface, the emitted energy is similarly distributed, making irradiance—not total electrical input power—the relevant metric. In […]
