Well we all know these big diodes have astigmatism. Can anyone grind a singl lens to correct for it? More cylidrical for the fast axis and less on the slow? I never seen anyone attempt this. Im sure each different diode will require a different setup for the grinder just like an optimologist...

First n a yellow laser, second a programmable graffiti device to project your words onto a wall or large object or smoke

Oh my. After reading this thread...I propose we have a Darwin Awards show at the end of the year. No way woyld I want to be exposed to Xrays or allow my kuds, if i had them, fool around with Xray equiptment. The idea of a porrtable xray machine is one thing, but to point the xrays at anything...

COD? Deep fried or battered. I still get light from one of the bars https://youtu.be/fVJDKIUJ7p8

Lipstick laser and advanced light sabor. Possibly interchangable moduls and lens assemblies on both units. Different strobe effects. Power and battery size options easily changed as well.

I just got a letter suggesting their batteries. He suspects the tail device might not be working right. It was made for a five watt laser to begin with. So Sanwu is sending me the correct componants to put into the tail section along with the new batteries I ordered. Anyway the weird thing is...

The host gets at the head hot but not the batteries.

It got warm quickly but not putting out the full potentail laser. Al the bars lught but are dim. Could the driver be fried? Or. Are the batteries just garbage

Iguess these junk batteries wont drive tge 7 watt correctly. It gets hot quick but not outputting a full beam

The batteries were ultrafire 18650s that sat in a drawer for more than a year since the last charge. Im sure I can get much better ones at the nearby vape shop

Just got my mudule in. I had a 5 watt silver. I sent for the 7 watt module. When I examined it, it lookes like it is open canned to let more laser out and more heat syncing. They sent back a G lens as a bonus. I just installed the batteries...half dead. This thing has a kick like a mule!!. It...

I tried that with mixed results. I combined two 750 mw. It was iffy at best. Some loss becaus the beams were oval shaped and when i crossed them, there seemed to be a 25 percent total loss from the sum of the two.

I consider the 405 nm purple, the 445nm a deep indigo blue. The 445 looks purple because of the camera viewing it. This also holds true for infrared lasers, they show up as deep purple even though they appear faint red to the human eye.

Are you still in Thailand? Stop by a restaurant called "Eat Me"

I was running the 5 watt about three minuts....way too long. Before i knew it the host got hot. I shut it off but too late it died a painful death. I expect the new mudule in a week.

If it doesnt smell burnt, pergaps the battery isn't making contact with the module fully. I have put a neodinium magnet on the end of the battery in my silver to make better contact. Somtimes the module undscrews forward when adjusting the focus and you lose contact between it and the batteries...

Watch the runtime on these. I burned up my 5 watt silver running it too long while engraving with it. It woyld be nice to have a momentary button near the head. Yes it will engrave a rock. Since I did order a new module, i upped it for the 7 watt for the same host. I did have a syfy laser that...

Welcome from Florida.

Re: FS: Sanwu Laser store - R/G/B handhelds x3 BE & Stainless steel "The Spiker" rele Very. I have several from them. Great support too

Not to derail your thread, they,photobucket, screwed up my website with that nonesense and cost me customers. That is one awsome beam. It will outshine my 7 watt Sanwu I bet
