Default Re: (Where to Find) 5W 650nm C-mount w/Fac Red Diode.

I like the power of that diode, but the divergence is rather high and the wavelength a bit long. If you need the power for something, that is one thing, but if you just want a bright beam take a look at the difference between 1 watt of 638nm and 4 watts of 660nm:



I don't think you will see that 11% difference.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

I'm just going for some of the rarer builds. I'm probably going to sell my common builds soon as I quite enjoy searching for more difficult lasers and diodes.

I just like being able to say that I have a custom build that would be tedious or difficult for someone else to try and obtain

Default Re: (Where to Find) 5W 650nm C-mount w/Fac Red Diode.

I want to build with that diode too, but don't have the money to pour into that right now, if I could find the diode. What I would do is expand the beam to several inches to get the divergence down. I keep thinking about the relative perceived brightness being close to the same as a over driven 700mw 638nm red diode, so that cools my jets some, I guess that's the larger reason I can't seem to dig up the money for one. If I were going to build, for my wants, it would probably be better to PBS cube combine two 700mw 638nm laser diodes pushed to 1 watt each and then expand that.

I can appreciate the desire for a rare 660nm high power red laser, I've never seen posts regarding one showing the beam, except for Styro's photo's.

Yeah, I'm fairly young with a good job at the moment so I save up bits of my pay checks for bigger builds like this. I haven't had a 660 before and I'll definitely make sure to get lots of pictures
