Figure 11. Removing the Cold Mirror
When replacing the cold mirror, insert the closest reflective side in toward to
optical assembly. To determine which side is the reflective side, place the point of
a ballpoint pen on the edge of the mirror face and look to see if a gap exists
between the pen and its reflection. NO GAP indicates the closest reflective side –
place this side IN.
