The reason that plexiglass is bad to shoot through is that it
scratches easily. The scratches diffract the light that goes through
them and generally degrades the image. Glass is better because it
doesn't scratch as easily.

Plexiglass actually transmits more light than glass and doesn't have
the green tint that glass has.
