One-way mirror

[franco malgarini]

I need a one-way mirror, as shown,
that on the one hand makes all the light entering
and on the other, reflects

Is there anyone who knows where I can find it?

These one way mirrors have certain criteria which must be observed for success and may work against your intended use.
the side with the brightest light will be the mirror side ,and the mirror effect at its most reflective state requires no lights [or very very minimal] on the Viewing side.
AND THIS CAN BE FLIPPED  with just the flick of a few light switches making the hider suddenly visible to the observed ...

I am certain there are persons here who can explain the reasons for this , I am just making you aware of potential issues
which you may not be aware of with this material.

I think any mirror is like this - you can look through the back of it

Also, although perhaps these are obvious. 

No mirror is 100% reflective
and
Only a vacuum is 100% transparent.
