Light up well, works with 3v. To couple to the laser machine put in Series a resistor so that it has a voltage drop of 2v, since to power it is used 5v
o***g –
The point is very large at 2 meters away but meets my needs
Customer –
Nice product
R***o –
Arrived fast and well packed Product with quality
F***E –
In general good, but the cross is not completely symmetrical and at short distances this defect becomes more noticeable.
E***u –
Everything as described
Customer –
Quick delivery, choice items but work as described. Works with 18650li-ion and usb. I cant say anything about power rating but the lasers are decently bright. Good value for the price. I can recommend store and the lasers.
O***o –
Excellent product for the price. Easy to use. Easy focus by turning the cap, then only fix it with a drop of superglue. Very satisfied
I***r –

Awesome little thing, I installed changed the diode with a 150mW diode and now it’s burning stuff 🙂
Customer –
Well received.
H***E –
Well received.
T***n –
Eylar badly, the line is doubled. Bof.
U***r –
These are good-quality 650nm, 5mW visible dot/oval spot modules. They will operate as low as 2.8V and contain the constant-current drive circuit which limits the laser current to about 20mA or so, which is ideal for battery powered projects. This model allows the focus to be adjusted with a simple zero-backlash knurled ring. So you can also adjust it to generate a more rectangular collimated beam for spatial coherence experiments. They both arrived on time and in good condition.
