OPHIR Head 170298

Just wondering if anybody knows much about this OPHIR head? The part number is 170298 and has on back 150W-A-.04-Y. Was told that it is for CO2 and YAG lasers. My main interest is if it could be used in a LPM for visible spectrum? And how much do you think it would be worth?

Adam, I don't know if this will help, but a while ago, another member picked up an Ophir 150W head. Here is the thread: http://laserpointerforums.com/f51/ophir-head-help-88713.html

Thanks for the link. That thread was actually what stopped me buying the head immediately, where ultimatekaiser mentioned the coatings might be wrong. I've read through it a few times but just wanted to see if any other members had experience/knowledge of that specific head.
