I'm looking for a cheap material to use for a strip of laser reflective mirror.
The object of my design is to have two parallel mirror surfaces that will bounce a laser beam back and fourth. The beam "grid" will be around 5'x5' with beam spacings of 1". If you haven't already guessed, this is gonna be a sensor that will detect an object >1" wide moving through it. As long as the beam makes it to the end of the grid without excessive distortion it will be fine, a simple light sensor is on the other end.
I've tried mylar but it's terrible after the first reflection. I have a polished steel credit card case that works great but I'm lost on where to find a long strip of the material. I'm thinking of trying out some "mirror tapes" but I fear I'll run into distortion much like mylar.
