Laser Module 405nm Violet Purple Blue Laser"Dot" Diode (Adjust Focus 5mw DC3V-5V)

Working out of the box, the laser module performed as expected. Unfortunately, I do not have a power meter, so it's impossible for me to test the optical output, but it's enough to surface burn materials and heat them up If it was exposed to colored plastic or wood, I am sure it would pop balloons or ignite In order to achieve good focus out to ten feet or so, the collimating lens must be focused properly. It is easy to do this from several centimeters away. As far as my fluorescence experiments go, it works perfectly. this photograph, I am drawing on thermal cash register paper using the heat generated by the beam. )

The electrical performance was not what was Using the module at 5 volts, I found it consumes 70 mA. At 4V, 130mA is consumed, and at 3V 260mA is consumed. A 3V battery. In point 5 above, we discussed Several modules tell me that the 4V current is increasing again, but I only have one and I need it, so I didn't push it. Although the advertised data indicates a maximum voltage of 3V, I think this module should be operated at 5V The temperature will be a little cooler if the lid is closed. Despite the small flaws, the book is still a valuable resource. A lot of check boxes are available on the label for wavelength, power, etc. , but none are selected. An item that appears to work fine has a small scratch on the lens, but the scratch is mostly out of the beam and does not seem to interfere with It was messy inside the collimating optics due to machining chips and dirt specks. With all of this in mind, there is no denying the incredibly low price, and that is why I gave You should inspect the lens before sending it back if the output is low/messy. Before returning the device, unscrew the lens and look for dirt or foreign objects. In shipping, it would have been pretty easy for dust and debris to fall onto the laser and completely block the beam. It's impossible to get brand-name bare diodes (without a case or power supply) for twice this price, and some comparable modules are $50 or more You can expect to pay between $500 and $750 based on the type may purchase more of these in the future, at which point I'll be able to comment on the quality and consistency of the lots, but my experience with the one I ordered was great!.

In addition, The lens is adjusted all the way in so it doesn't focus and makes a wide beam of light. is so beautiful as it passes through the As you can see in the video, I am using it with my HTC Vive to stream Beat Saber.

With this power range, you can put light effects without burning things but while at the same time they are bright enough to be seen (something that violet lasers may Fog would make this image look amazing. A blue laser's beam will never be as sharp as one created with a red or green laser, but this is to be expected. As a result, this unit does a pretty good job of focusing. It runs at a speed of The device runs fine at 3 volts, I haven't noticed it getting hot or had any concerns about it being continuously run, but I will need to test it further. In the future, I'm likely to pick up more of these!.

It was dead when it arrived. As I opened it up, I assumed it would be like other people's issues, but it does not seem that there is a (I don't have any electrical background, so I can't tell you what the problem is). See pictures for details. Clearly this manufacturer doesn't adhere to a quality control system, which is extremely In order to ensure that I provide an accurate review, I ordered a replacement from Amazon. Once I receive my replacement, I will update this review or add another one.

I have lost focus after 30 minutes and I'm burnt out For forty DC power converters barely moved past 5 volts when using an adjustable one. A play laser for my cat can handle 5V (which is what the cat's play laser needs). The total number of points.

Instead, it emits a faint, pale purple glow. There is a possibility it is high in UV, but we could not measure it. Having the same power rating as a red laser can blind you. Unfortunately, it couldn't be used for the purpose I intended. In terms of physical quality, it was good. There is an integrated heat sink groove in the case. It was good.

I bought them for intense UV curing I bought 6 more, but only 2 are good out of the 6 I purchased. The first 3 worked well, so I bought six more.
* In the photo, you can see the handle that was retrofitted onto the right model is from the first batch and the handle that was retrofitted onto the left is This is the worst disappointment I've ever experienced!.

I hate this bad. There is an issue with the laser alignment or focus. A tightening of the screw does not solve the problem. In other words, it makes a freeform shape rather than a dot. Working on a project with glow-in-the-dark paint, I am using glow-in-the-dark The laser is powerful and will activate the paint, but the shape of the light is not suitable for paint. It would be worth the effort for me to return this if it wasn't worth it.
