Dynatron 820 Laser

For the collector of unique vintage electronics: The Dynatron 820 is considered a pioneer in the early clinical adoption of low-level laser therapy (LLLT), which is the precursor to modern red light therapy nowadays. This comes with the 1983 user guide and investigational protocol that came with its initial release to the clinical market. Still works, especially the Hughes helium neon laser tube which puts out 2.75 mw of pulsing 632 nanometer red light, not great compared to the powerful LED light banks in modern red light therapy. $1,200 or best offer.
