Okay thanks for the explanation and endurance :D
So I guess aixiz modules also just work with a single convex lense,
and by moving the focal point into the center of the diode we get
a nice low-mrad beam that is still capable of burning some stuff.
I see... 150mA is the regular "wuzz" current for burner diodes
and 300mA is the current LPF users run burner diodes on 8-)
So 300mA should be ok (with an eye on the temperature) with
any harvested burner diode?
just found the sony dvd burner diode data sheet directly from stonetek...
it says 150-170mA operating current...
NOW I'm confused...
If I harvest a diode from a dvd burner (like my old NEC that may be used for this)
how do I find out how far I can go with the current for the diode without...
Sorry for asking again, but is "the 16X RED diode" not the same thing as a red laser diode from
a 16X DVD-burner?
Or why do other people run their DVD-diodes with a maximum current of 150mA, if
you tell me 300mA would be fine?
Technically (from the view of a physics student) converging and then parallizing (does that word exist??)
should work.
If I put the concave lens in front of the laser, the beam will diverge even more that it does without lenses.
If I then add a convex lens in front of the concave lens, I could...
hey!
I am quite new to lasers, but I have understood everything about it.
I plan to build a LM317-driven DVD-burner laser module.
I have access to small glass lenses from old cameras, both concave and convex.
Now I could not found a serious tutorial about building a optical system to
archive a...
