If you didn't happen to know what LCC stands for, it's Long Closed Can diode. I think it's pretty obvious which is the LCC in these pictures ;) Another way to tell is by the AR coating on the window. On IR diodes, the coating will be a very pale, light blue. On red diodes, the coating is a very...

YVO4 is much more efficient for our purposes.

I love these batteries! They are definitely the best of their kind. Flaminpyro gave me a great deal on these, offering two extra batteries to the four I was originally going to buy. I am using them for a portable HeNe laser (as seen in my sig), and I needed some nice batteries to power the...

I got my Lithium D batteries from Flaminpyro a few days ago, and I can only say good things about the transaction. I sent him a pm requesting for four batteries shipped, and he instantly replies saying that he'll throw in two extra batteries free of charge. What a deal! A few days later I...

In theory you should be able to expand the lens using a concave lens followed by a medium focal length convex lens. Getting the expander right shouldn't be too difficult with the right lenses, the only problem I see would be aligning them to get the best divergence. Unfortunately I don't have...

A small recommendation I have to make is to glue the circuitboard to the interior of the altoids can. Moving parts are not good for any type of project, and the board could easily be ripped out along with wires to your Laser Diode. Just a word of advice that I'd advise for you to take :)

PM sent :yh:

The line is normal in all LOC and LCC diodes. It has to do with the magnification of the actual die of the laser diode, and is an artifact of the laser itself. It is not something to worry about :yh:

The micro boost driver is in fact a boost-only driver. So the input voltage has to be less than the diode's voltage. Try using a lower input-voltage, this may solve the problem.

Hmm, I guess I'm the only one to notice the tumor on the Aixiz Module :whistle:

I'm looking for quality over ear headphones for around $100. Can you guys recommend anything?

Congratulations to FireMyLaser, whose video made it to the front page of wimp.com!

56x is common for a CD reader/burner. See if you can find any other numbers for DVD reading/writing speeds.

I'd say a low-powered infrared laser. They'd be good for practicing soldering, pressing into a module, etc, but you'd be better off buying an LPC sled for red or IR diodes.

Destructive Interference

I think 250mA is a bit high for a SF-AW210 diode. They are known to be in the power range of the 6X, so around 200mA or so would be fine. The reason why some people's diodes have survived at 350mA is because they had freak diodes. Mine is set at 160mA, and has degraded after a few months of use...

Ok, now I think I've seen it all... 8HE9DLuAT8A

Wow.. I am speechless.

Re: Blu-Ray Emitting Other Colors... This has been explained before, but I'm not sure what really causes it. I can tell you that it is perfectly normal in Blu-Ray diodes; the artifact is even in my SF-AW build. Just enjoy the rectangle :angel:

That is all.
