I am working on a project where I am putting an IR sensor similar to what we use IR module for Arduino.I just want a material that can pass the IR rays but it should be opaque to visible eyes .Like for example the material which is been used in front of T.V or other IR compatible remotes ..

I would suggest using a silicon waver or something similar (e.g. a shard of a broken solar panel), because silicon is transmissive for infrared frequencies, but partly reflects and absorbs visible frequencies of electromagnetic radiation.
