springs can be found in pens too!

-The Original specs of the diode- I have the same one and it works. It is fairly high power. I have burned my hand with this shit! You can see my thread, it is around here somewhere with CNC in its name. I bought from techhood too. About the driver: make your own configurable mA driver...

Hello! Thank you for your interest! The diode has been bought, has arrived and has been in my CNC for some time now. It works perfectly for engraving wood real deep (gets a very black line) and almost cuts cd case plastic (I believe that running at lower speeds will do the trick). I even made...

The army has made something not exactly handheld but with plenty of wattage: Watch the Navy?s New Ship-Mounted Laser Cannon Kill a Drone | Danger Room | WIRED "Within initial limits. The Navy won’t say just how many kilowatts of energy the LaWS’ beam is, but it’s probably under the 100...

if the lens was an acrylic one wouldn't it melt by the 200w of 405nm?

As we know them, Aixiz modules come with a kind of lens format. They get screwed with a spring at the front of the module where the laser can opening is. My thought is the following. I own one laser. A Nichia NDV 4542 405nm 200mw laser diode, in an Aixiz module with 3 element lens mounted in...

When is a PWM source properly designed? I haven't forgotten the goggles, I will buy a pair when I choose the diode. First of all, I want a first meeting with "laser diodes" so I can't spend that much (70$) for something I am not sure how to use... Can you please answer me some of the rest...

Hello. I am planning on another X-Y laser engraver. This one is not made by printer and cd drive parts, but with parts I bought myself to ensure a big enough working space, enough motor torque and for the joy of assembling all those by myself. Being a newbie in laser diodes I almost end up on...
