Mirrors for reverse vending machines

Deposit return machines use sensors to scan the returned empties and read the barcode. With Bte vapour deposition technology, we coat components of the recognition unit, which is made of glass. 

The machines use the sensors to detect the single-use deposit logo and the printed barcode. The weight, shape and colour of the bottle are also determined. It is particularly important to minimise reflection and avoid distracting reflections. This is the only way the recognition system can work quickly.

Copper mirrors or highly reflective mirrors are used, for example. We can cut these to customer-specific dimensions thanks to our own laser cutting, including free-form mirrors.
