  1. June

    The wavelength is exactly 405 nm with a narrow bandwidth. I’m not sure if it is made that way, but I could actually tune the intensity of the light by changing the voltage input. I’m using it for my fluorescent test and it works great!

  2. Rad

    Excellent, I use this laser to test absorption of UV light on different materials for 355nm laser applications. It is brighter than it appears. It tested 47mW using a calibrated power meter.

  3. Spider-guy

    Had to rig up a USB plug for supply but then was tickled to see that this wavelength makes lots of pigments in the environment fluoresce. Just please be careful to avoid peoples eyes because the 405-nm beam is far more powerful than it looks on a non-fluorescent surface like metal.

    I bought this for use in a light show I’m designing. The color is a nice violet blue, clearly visible in daylight, and the intensity will be perfect for what I’m using it for! This is a great power range for lighting effects since it won’t burn things but is bright enough to be visible (something violet lasers can struggle with). It will definitely look great in fog. The beam will never be as sharp as a red or green laser, but this is an expected trait of blue lasers. That being said, this unit does focus pretty well. Running at 3.3 volts, I haven’t noticed it getting hot or had any concerns about running it continuously, but I’ll need to test this more. I will likely buy more of these in the future!

    We are using the laser in a vision application. Using the dot to highlight a shoulder in a part so the camera can see it easier. Good value

    The media could not be loaded.  I adjusted the lens all the way in so it doesn’t focus and makes a wide beam. It looks amazing as it moves through fog. I’m using it attached to my HTC Vive controller when I stream Beat Saber, as is seen in the video.

    The laser module worked out of the box. I do not have a power meter so I can’t test the optical output, but it’s enough to heat up materials and superficially burn into darker-colored plastics, wood, etc. I am sure it would pop balloons or light matches. Focusing the collimating lens is essential for this, and I was able to get a good focus from several centimeters out to ten feet or so. It works perfectly for the fluorescence experiments I’m doing. (In the photo I’m using the heat generated by the beam to draw on thermal cash register paper.)Electrical performance was not as expected. I found that the module consumes 70 mA at 5.4V, and 130mA at 3.3V. Above 5.4V current starts to climb again, but I only have one module and I need it, so I did not push my luck. In spite of the advertised data I would be inclined to run this module at 5V, not 3V; just to keep it a little cooler.There are some minor flaws. The label has a lot of check boxes for power, wavelength, etc; but none are checked. There is a small scratch on the lens, but it’s mostly out of the beam and doesn’t seem to affect operation. There were some machining chips and dirt specks inside the collimating optics. However, even with all of this in mind, the price is incredibly low, and this is why I give it five stars. If you get one of these and the output looks low/messy, unscrew the lens and look for dirt or foreign objects before considering a return. It would have been pretty easy for a piece of debris to fall onto the laser and completely block the beam during shipping.I can’t buy brand-name bare diodes (without a case or power supply) for twice this price, and some comparable modules are $50-$500 depending on what kind of performance you need. I might get more of these in the future, and then I’ll be able to comment on lot consistency and quality, but my experience with the one I ordered was very satisfactory!
