Tatsuro Matsumoto; Inventor of the EMS, Erecting Mirror System. EMS offers non reversed upright image with no additional undesirable abberations.
I received the second shot of the Corona Vaccine on 30th of July. Happily,there were no vaccine side reactions at all, and my evening workout was as intense as usual.
The mirror of the former EMS-UM was cut out from the normal elliptical mirror of 42mm by 59mm into the final shape. That meant not only a lot of time and effort in the processing, but also the anxiety factors on the negative effect over time.
Now, sufficient quantity of the final shaped custom made mirrors, 32mm x 60mm, for EMS-UM are secured and announce the release of the New EMS-UM. Quicker delivery and further improvement of the durability will be expected.
The section of the light cone on the EMS-Mirror is the ellipse of 1:2, while that of the 45-deg mirror is 1: 1.4142….(sqr-2).
