Used laser

[EduardoMDSousa]

it's not a problem but a question, I didn't find any other way than to ask about the project,

hello, I've been looking at the laser you recommend, but I don't see the data for it in the specifications.

How many mW is the laser you are using?

this is because I can't order to my location.

although I can get others of the same type, with focus on the beam, but the ones I use are 1mw of power,

but the supplier has other powers,

although I think that here, given the proximity and the possibility of exposure to leisure, the less powerful the better correct?

but I would like to know your opinion, what do you advise, 0.5mW, 1mW, 3mW ...

the ones I've seen besides the that I use professionally are used as pallet position location pointers on forklift trucks.

have the specs output wavelength 635-650nm output power 1mW ( 3 and 5 to but we use only 1mW)
Op current 50mA
Op Voltage 3v/4.5v

thanks

Many thanks for the reply

0.5mW is the lowest and least harmful power, I'll try it then
Thanks.

Hi @EduardoMDSousa sorry for the slow response. I use a 5mw laser. It's a pretty typical power rating for off the shelf laser pointer modules, and shouldn't bee too bright. As with all laser hardware, be mindful of reflections and don't point it at your eyes, but it hasn't felt overpowered during my testing.

If you could get one that focused at a closer distance, you might be able to get away with lower power ratings.

Hi i Will test this 2 models

From the 1st vendor i AM traing to get only the head with focos , and the driver separated , to be smol and light

The printer Will be closed with black pannels ONLY the front i need to see how i Will do it, so i dont have reflections ,

Since it Will work in a range 3v to 5v i belive if it work good at 3v the power Will be less and almost armeful but i AM not a cientist 😁, i use 1mw or better say i work with 1mw lasers on forklifts for positioning , to the driver know were to stop on right spot and its the palet in spot on the rack . So i belive 0.5mw it is safer

I AM talking with the laser suplyer , cam you tel mi the ideal line length and working distance

These are things that will require experimentation. We are currently working on figuring out the same thing, and we don't have exact answers for what works best yet.
