EMS-UML with the largest mirrors ever made

The largest mirrors are installed in the same housing set up with the normal EMS-UM. This is the New EMS-UML.

This footage is the perfect teacher of the EMS-PRINCIPLE.
You can know the perfect connection angle by seeing the normal entrance circle, which is just like watching through the opened-book shaped mirror pair.

A pair of rectangular mirrors, the perfect teacher of the reflection study!
