OK, thanks to Mixedgas and Catalanjo I've reconsidered my harsh (at the least) and unfair (at the most) comments above and now want to look closer into all the early devices for medical applications. The wood sides and complexity of the control panel also drew me in, so I added the Dynatron to my collection (#70).
Steel might be real, but wood is good.![]()
Well I received the Dynatron yesterday and found the corner took a good bashing in shipment. It was wrapped well but put into an oversized box with too few random sized pieces of styrofoam which allowed it to go crooked and hit on the bottom corner. Incompetent packing is the biggest risk with old lasers when bought off ebay (and sometimes from those who you'd think would know better!).
Anyway, I glued the corner back together and just finished cleaning it up. Dynatronics is a big company today selling all kinds of devices and equipment for physical therapists. This device was a very early one for Low Level Laser Therapy, that was never approved by the FDA. Just not enough power at the tip.
Here's a pic showing it working. I love the LED backlighting of the laser splat logo! The LED is a good distance behind the front panel so there's a parallax effect with it. Same to a smaller degree with the other LEDs. Very '80s! There's a Melles Griot he-ne inside the case, and the optical fiber that takes the light to the handpiece is inside a 4" long metal tube that goes into the socket on the side.
