Hello. I bought a two-color green and red laser projector Technical data: - Laser power: Red (650 nm)

Show what this laser looks like.

Something like that is it can still be opened, but I have failed so far, maybe inside he writes what power is and what this diode -laser looks like

To open it, unscrew the ring from the front. There is normally a key in the shape of it for mounting the wheel in the grinder. For this two holes at the front.

I was able to open and properly cut this roller, and inside there was something so tiny, there are no signs of tension. In that case, how to replace these diodes? it can only be replaced by this tension when I checked the voltage, how the green laser is lit it shows about 2V, when the laser is completely desoldered, it is up to 12V, maybe with red it will be the same

After all, you have in the data (first post) and laser power and its color (wavelength) - you need to find the same and insert. The voltage is either regulated automatically by the DC power supply or (in simple systems this also occurs) by a series resistor connected to the laser power supply circuit. Of course, you know that laser radiation is harmful to your eyes? Under no circumstances look directly into the beam! Even a laser of this low power can permanently dazzle! PS You completely unnecessarily smashed the laser housing.

Thanks. I stripped it out of curiosity and it was already out of order. And besides, I don't know about this type of thing, that's why I'm asking, is the example of the laser module wrong?

same wavelength 650 nm and the power is halved 50 mW - 100 mW I just don't like it

Do you think the power will not be enough? If the designer put 100mW there, then for some specific purpose?

Thanks I don't know, maybe it's enough, the green laser has (532 nm) < 50 mW, and I don't even know what the mW designation is So I can take a chance and buy a laser module - a 3V red point laser and it should work

Compare powers - you'll know.

I bought this diode, came, soldered, sacrificed 10 seconds and that's it
