Hello. I purchased a custom laser you made from somebody you sold it too.
The EDC 1650 1000mW 638nm laser.
The lens does not focus, even when I twist the lens. As if there is no lens.
Can you help me? Thanks.
I guess I should update how my project turned out.
Taking the laser module apart, I found lots of front-surface mirrors.
I got more use out of the front-surface mirrors than the IR diode itself.
Because the reflective material is on the outside, light does not pass through glass and loss...
Been a long time sense I posted here, this website is almost nostalgic in a very weird way.
I have sense been working with robotics education. Lasers and flashlights where kinda like a gateway drug for technology and engineering. A drug that is rewarding and addicting, but doesnt ruin your...
Your 455nm pen is incredibly elegant. I think you found the perfect application of the 455nm diode. Is there any thermal issues in the pen that would require any duty cycles? How does the brightness of 165mW compare to a 50mW green? How safe is this for indoor use?
I've actually noticed the same thing.
I've also noticed that when its cold and not warmed up, the beam tends to (what it looks like) split into 2 separate parallel beams, that are really close to each other. Anyone else notice that?
I can relate. I bought x5 50mW laser pens from them. 2 @ ~50mW, the other 3 were overspec'd. Also, your right, their shipping number is complete SH*T. It didnt work for me either, nor did my emails.
If shipping time is what you dont like, then DX would be a nightmare.
