Default Re: Just a few questions! For my first laser Build

yes 100-120mA would be really good. no one knows how long the diode will last at that current because none of them have died.

it will be very visible beam.

Cool thanks!

I've heard Axixz Glass lenses are bad and Weaken the beam. I Think also it hurt the Diode? is this correct?

I think the Lava Driver can take 2-3 AAA batteries is there a benefit for using two or three?

Can't wait to assemble It, well as soon as DX delivers

ehm, I've read somewhere that if you use a glass lens that it can improve your laser power.
because by some red lasers someone had with an acrylic lens ~250mw and with a glass lens almost 300mw.
so i would think that it would work also great with a blue diode.

i think that the glass lens lets more light go out of the module, and lets less light bounce back to the diode so the diode will get less hot.

Depends which glass lens is used. If a merydith glass lens is used then the output power is indeed higher than with the aixiz acrylic, however the aixiz glass lens does not provide any output power increase infact it lowers it by 20% IIRC

So unless you are going to shell out for the merydith module with the glass lens ~50bucks your best bet is a standard aixiz acrylic lens, atleast until IgorT's super-special-ultra BR lenses become available.

ok, but why would they even sell aixiz glass lenses if they are worse but more expensive than the default acrylic lens?

the Aixiz glass lenses are AR coated for 650nm light (red light), not blu ray (405nm) light, so it is not good for blu ray lasers, but very good for red lasers.

Exactly what sk8er4514 said.

Glass ones are typically coated for the red wavelength to pass through clearly. You can buy glass ones that are meant for the blu ray wavelength. Heard there was a group buy on that.

In short:
Acrylic can work for both red & blu ray
Glass one (from Aixiz) will only work on red
