well it could be a lot of things ... from the finish properties of the
mirrors, location/strength of the light source, to max_trace_level
setting in the global's block. perhaps you could provide some more
details ;-)

As you use a mirror, you need to increase your max_trace_level by 1 or
more. If you have 2 mirrors, you must increase by at least 2.
Make sure that your mirror(s) is effectively a mirror: finish{reflection
1 ambient 0 diffuse 0}
Make sure that the second glass porthole is realy transparent.

Find inclosed the .pov file
#include "colors.inc"
#include "textures.inc"
// Fond de la scene
background {Grey}
light_source{ <1000,1000,-1500> 5}
#declare c=
camera {
location <1000, 0, 1000>
look_at <1000, 0, 0>
angle 15}
camera{c}
// Objet
cylinder {
<0,-200,0>, <0,200,0>, 50
texture { pigment { Red}}}
// Porthole
cylinder{<500,0,0>, <510,0,0> 100
texture{pigment{Clear}}
interior{ior 1.5}
}
cylinder{<750,0,0>, <760,0,0> 120
texture{pigment{Clear}}
interior{ior 1.3}
}
#declare mirror =
box { <-150,-150,0>, <150,150,10>
pigment {color Green}
finish { reflection 1 ambient 0 diffuse 0 }
}
object{ mirror rotate <0,-45,0> translate<1000,0,0>}
thank you for helping me

Adds:
global_settings { max_trace_level 30 }
produces:
Max Level: 7/30
Default is 5, too short for your case.

Software is like dirt - it costs time and money to change it and move it
around.
Just because you can't see it, it doesn't weigh anything,
and you can't drill a hole in it and stick a rivet into it doesn't mean
it's free.
