A Class 3R laser is considered safe if handled carefully, with restricted beam viewing. With a class 3R laser, the MPE can be exceeded, but with a low risk of injury. Visible continuous lasers in Class 3R are limited to 5 mW. For other wavelengths and for pulsed lasers, other limits apply.
The 'Laser' target systems that I know use IR for hitting the target. The gun is a variation on the TV remote, with a lense to focus the IR. Yes, you can focus IR just fine.Or use a LED that has a narrow beam by itself. The target uses an IR detector module, like a TSOP1738 or a newer variant. The laser is only for the spectacle. (Indoors they use mist machines to make the laser vissible, outdoor systems often don't use a laser at all).es, you can focus IR just fine. Or use a LED that has a narrow beam by itself.
