Looking for small laser modules

[69morpho]

Hi,

I am experimenting with small lasers modules I took out of laser pointers to make a little light sculpture. Instead of taking apart laser pointers I now want to simply buy a quality laser module with built-in spot optic. I assume I have to limit the amperage with a current limiting resistor otherwise the laser would simply die, correct? If I use the blue 445nm diode from Aixiz http://www.aixiz.com/store/product_i...roducts_id/416 with 3.2 VDC and 90mA operating current the required resistor would be 3.2 VDC divided by 0.09 A = 35.555 Ohm. Do I need anything else to properly drive the laser? Any other US companies that sell small laser modules?

Thank you for your help!

I think thats a typo , blue lasers typically need more than 4 volts.
The graph states that it needs 5v.
It also says a driver is included.

Here are a few other U.S. companies that sell good cheap modules.

• DTR
• Survival Laser
• Sci-Fi Lasers

You should really use a driver board to power the laser. DTR has links to some and Survival sells them outright. The Lazereer X-Boost are among the best.
