Hi! I've recently bought a 1.5W 445nm laser diode: it works with 1-1.2A, but no informations about voltage or model. Another questions is what I've to use to focus... Aixiz module can be useful?
I'm quite noob, but more interested and fascinated with lasers :angel:

To power the driver, you will need a constant current driver. As for the voltage, it will be around 4.5V to 5.5V for a 445nm laser diode. Just keep in mind that the voltage doesn't really matter as long as the voltage is in that range. Read all the stickes and you should be able to get your answer. For the model, please post the link where you bought the diode from?
 
nice new laser.,.
i thinks that's really good...

I've already got it, it's a variable current regulator capable of support up to 1.8-2.0A. I bought the diode on eBay and the object is no more available now :can:

Thank you.. Hope to make a good build :thanks:

How can I focus the laser? When I put the diode in the aixiz module and I insert 3 element glass lense, the beam is a big circle. Else I'm able to focalize only at a 2/3 inches if I screw completely the lense...
 
Unfortunately you haven't given us enough information to be of much help to you. To focus your laser you will need to place a collimating lens the correct distance (approximately the focal length of the lens) from the diode emitter. You might try flipping the lens around if the current orientation does not allow it to get close enough to the emitter. If you can include some pictures and measurements then we might be able to better help you with your issue. For the time being, an unfocused laser might be safer while you wait to get some safety glasses.

Just wondering can anyone see the image he linked? It looks like a tracking img to me

Sometimes the original lens for the module you bought is too small and not enough precision. I purchased lens that is a little bit longer than the original that came with it and it made my focusing more precise. Make sure you buy the correct lens for your module though. Hope that helps

No not visible your right, don't quote posts that have those images.

Most lenses have a lens barrel that are 10mm length, some are only 8mm and those are mostly the acrylic lenses and are short enough that they have to be screwed in almost all the way and you may not be able to use a focus ring with AixiZ type modules. The 10mm length lenses are much better. There used to be some that were even longer from DTR but he hasn't had them for a very long time. If the lens is a little loose and the internal lens spring isn't enough to keep it tight, you can try the external lens springs sold by Survival Laser or you can use a tiny amount of Teflon/plumbers tape on the lens threads.

Yesterday I bought this:
http://www.amazon.com/gp/product/B00B6DOA0G?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
As can you read in the product description, it should be the correct length (10mm), right?
 
The lens i bought seems like there is an internal screw of the lens. The side thats inside the module, tried turining but cant turn.is it possible to turn?

Where did you get the lense and the module?
If you are using Aixiz housing or any other standard module, the lense holder should be m9x0.5 thread

You mean the one in the lens itself? Yes but that just holds the lens together, if you are able to unscrew it you can take the lens apart.
