Those guns are not cheap. I once worked in a startup that wanted to put thermal cameras on commercial planes to measure volcanic ash concentrations. The cameras had to be behind a special glass that is transparent for thermal radiation. But as the glass size exceeded certain size, it required to certify against bird strikes. It turned out the cost of the certification was like 500K euros.
