I bought this module for a small project in making a burning laser and I found that it worked really well. I made my own driver for it to operate how i wanted it to, and the laser module worked really well with it. It also has a case surrounding the actual laser which is really convenient, as I would not have to buy one. I cannot really think of any ... Read more
The pricetag on this magnificient piece of technology was a dead giveaway. And the ease of use is a big plus But the rather fickle backside with somewhat wonky contacts made it worse in the quality department. And the general lighting was not as promised. The lid which I wanted to fit a diffraction grate was glued together unfortunately. Was for my ... Read more
1. Low price. 2. 3-7mW, not strongly 5mW 3. Compact size. 4. Big range of voltages(3-5v works normal) I have two units... one of them it is not focused (see attached image). Because this I can't use it in my project. Very good. I`d like to buy 10. Laser can be "overloaded" to more than 5mW without some problems. easuring real current consumption:... Read more
Price, price, price!!! You can't go wrong for under $2 for a 5mW red laser!!! It will fit almost anywhere! The power supply wires are somewhat fragile, and for experimenting purposes, should be removed and replaced with better ones. It's so tiny!!! Will fit almost anywhere! This is the perfect model for learning about laser technology - it's small, ... Read more
It's really really cheap, so if you wanted to, you could buy some just to play with or make things like pens or just for experimenting.
Worked well with 4AA even without any current limiting. The laser is visible at 10m even in broad daylight.
Since it's not very focused, it's harder to harm yourself just fooling around with it. Small, could be more ... Read more
Es un buen producto, es reisistente ya que es metalico, muy compacto tiene buen desempeño y gran estabilidad y sobre todo es muy facil de usar pues solo necesitas conectarle de 3 a 5 volts para comenzar a funcionar, en general de buena calidad por un precio muy bajo. Los cables un poco debiles pero aceptable. Ideal para pequeños proyectos ... Read more
1. Low price.
2. 3-7mW, not strongly 5mW
3. Compact size.
4. Big range of voltages(3-5v works normal) Wires are so thin, and can be broken.
Maybe so many UV, optics is not enouth focused. Very good. I`d like to buy 10. Laser can be "overloaded" to more than 5mW without some problems. I`ll use it to create direct-sight laser to UTP-lan link ... Read more
not so expensive
lazer is really bright
size is small connection points (soldering) is not good it seems like it is adjustable, but it is not possible
cables aren't enough long for me. but the laser module that i've ordered at the same time came with same length. maybe it is ok for the standarts i've searched nearly all the red laser modules in dx. ... Read more
Great divergence, amazing price and reliable power rating (5mw). Can be run for a while without heating up Nice solid dot. - very small & compact - Very useful for DIY projects
- Good working in various ranges of voltage
- Small and good design Wires were cheaply soldered onto the driver board, might need some re-soldering when the time comes. Other ... Read more
This module is Very compact size.Body length is only 13mm Including foundation bord, so we can incorporate it into the small unit. By individual , there is a variation in the output , so it needs to be checked Output Level before use. Soldering of Lead code is somewhat feeble , so I'm worried about damage during transport.
For now , I have purchased ... Read more
