... no, this diode is not strong enough and with a very bad beam profile, so the focus shape in distances bigger than 100mm will result in a distortet oval, not in a spot! - this 405nm-diodes can be found with powers of 200mW or 300mW, removed out of BluRay-writers ...
First comefcial SLA machines used HeCd-gas-lasers with a really good beam quality and focus distances of up to 500mm, I'm getting big problems with 2W@445nm-diodes and 150mm 8-)
