The transparent QHM - Holographic Mirror Film with which it is made prevents the duplication of the reflected image that would be obtained with the use of sheets of glass or plexiglass.
The holographic image is not obtained with a direct projection on the ZHM - Holographic Mirror but with the reflection and the projection, therefore, does not reach any of the zones that can be watched.
The flexion of the frame has to be imperceptible or it won't be possible to adequately stretch the mirror that will show folds and deformations of the reflected image.
The mirrors have to be stretched along the four sides in a uniform way.
of the mirror
1 - WCS - Strap + WOC - Eyelets + WPE - Perofix 27 cm
In this case the mirror must have a size of 5 cm per each side less then the inside area of the frame to allow the correct stretching of the WPE - Perofix 27 cm.
It is needed a perimetric masking, whose dimensions have to be of 20 cm per side less than the inside area of the frame, in order to hide the creases due to the punctual tension of the elastic hooks on the eyelets.
2 - pocket + 8FV - Glass Fiber Rod + WCG - Ratchet straps For experienced users, it allows to avoid the punctual tension of the elastic hooks on the eyelets but it however needs a perimetric masking whose dimensions have to be 20 cm per side less than the inside area of the frame.
