invisible to reflection/refractions

Can photometric lights be made invisible to reflection and refraction???

I got a glossyrefraction glass wall with a photometris linear light behind it… and the refraction only shows the middel part of the light, and not the full length???

How do you make a photometric light visible, in the first place?

please post a picture of what your talking about.

Sounds rather confusing.
