Wait, you mean I overpriced it? I thought I UNDERpriced it...

I have installed the lens both ways and took photos. One side gives me a nice-ish beam when screwn all the way out, and a line when screwn all the way. The other side gives me a focused point for burning when screwn all the way out, and a line again when all the way in.

Thank you! I hope I will be lucky.

I am selling a laser using the Mitsubishi ML501P73 diode ran at 1A, which gives me ~800mw. The laser was built by me recently, but I am now selling it because the laser is too powerful for me, and I am too irresposible and scared I'll hurt myself or someone else. Here are some photos of the...

Oh, wow, I didn't know that... I'll try. Thanks.

I have a 800-ish mw 638nm laser. I would like to sell it but I have no one to sell it to. If there is someone on this forum who might be interested, I would gladly provide more info.

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F332016073893 I have checked out the datasheet which says this is a "hologram laser diode". I still don't understand anything about it and what it does.

I was wondering, are there any low-ish power (5-50mw) 450, 405, 447 etc. nm laser diodes? All of the blue diodes DTR has are 500-7000mw (excluding the Sharp 488 diode).

I don't mind a power loss at all, thanks.

I am using the Mitsubishi ML501P73-02 diode, and I want the best beam specs.

Is this a good lens to buy for the mitsubishi 638nm 500mw laser diode? https://www.ebay.com/itm/638nm-Laser-Diode-Collimating-Coated-Focus-Lens-MP9x0-5x10-5-Half-Threaded-Frame-/141819513641

Ok, educate me on dummy loads, please. For instance, if I have a 1A driver, and my laser diode is supposed to work on 2.2v, how many diodes do I need in a dummy load? How do I calculate these things, and what do I even need to calculate? I know I should probably know these things, but I don't...

Uhm, yes, I did. However I didn't think SMD zener diodes looked like that.

Anode connected to ground? That seems a bit odd.

Yeah, I'm asking for the diode.
