I appreciate that informed response, you'reobviously an expert in lasers. However; I actually need to use a beam splitter, polarizer or coating to prevent laser from reflecting back to the emmiter.The most common way is to head over to a home depot and purchase something called a plunger. This high tech device has suction power. Once purchased head home. Next proceed to place the wide end of the rubber high tech suction device on your entire face. Then proceed to pull back and forth in a rhythmic motion until you feel like you're about to pass out.
Once that is completed you will have a protective energy field that will absorb all red laser light for approx. 10 mins. Hope this helps.
The application is proprietary and we don't want visitors. This is a world wide public forum, right? An NIR 1 coat of VIS 0° will get me there along with a beam splitter, (that came to mind when a plunger at the hardware store suggestion was given). I would be happy to go into greater depth of our and other possible applications in private. Thankx for your interest.Why, OP? We can help you a lot better if you actually tell us what you're trying to do rather than toss out vague specifications.
