Question about LPC-815 voltage

[StereoBucket]

Hello so i ordered that laser and now i was thinking.
What voltage can give me 250 mW power and what voltage can give me safe 5mW power.
Since i dont have laser glasses yet i was thinking to make a mark on my potenciometer so i know where to move it to get safe voltage.

i got my multimeter for amperes and volts now i only need to know what voltage will give 5mw and 250 mw

Laser diodes need constant current, not constant voltage. Your driver will take care of that. You're going to have to use a test load to set your driver though.

so does daedal circuit based on LM317 makes constant voltage or current?

 

[Ghostchrome]

daedal circuit is a constant current driver. It wil work fine.

Ok now i have 20 days till my laser arrives so all i need is to find laser glasses and build up soldering skillz.
BTW whats the cheapest red laser glases i could use with LPC-815

Yes, definitely get safety eyewear.

There's these:
Laser Glasses - Red laser beam protection 600-740nm :: Laser Safety :: Dragon Lasers

And these are a bit more expensive:
Eagle Pair® 190-470nm & 660-760nm Laser Safety Goggles

 

[StereoBucket]

ooo thats expensive.
Atleast not as expensive as an new eye ball.
Lucky thing i got 15 pants that are not under 50 euros so i sell one and buy glasses and really good glass lens.
What glass lens you recommend for red laser on aixis laser housing?

 

[Ghostchrome]

The acrylic lens that comes with the Aixiz module is fine to start with. You could also use a glass lens that is coated for red lasers like this one.
