i'm honored to be adding this to my collection.

I'm excited to be getting this unicorn of a diode. Thank you BillyBob! :thanks:

Is the focus adjustable? If so, focus it to a fine point and you wont see the dots.

well... dang it! I guess now I NEED one of each.

Is there much visible difference to the naked eye between the 486.8nm and the 491.8nm?

488nm @ $275 each I'm on the fence. Is there a minimum number purchased to get that price?

Hey there and welcome to the forum. You live in North Carolina? That is Awesome. My brother lives there also. What city do you live in?

Thanks for the explanation. I thought you guys were talking about a special lens barrel for the g9 lens.

I have to ask.... What is a gel lens holder? :thinking:

He was such a remarkable man. His passing is a loss for us all.

@ RedCowboy I have glasses for red, blue, and IR. I have a Laserbee. I have the old Meredith module that makes it easy to test 5.6mm and 9mm, as well as different lenses. Most of my diodes are from back in that days if sled harvesting and group buys. I was never really into the reds, so I'm...

Thanks for the suggestions and guidance. As I stated, I will be testing diodes that I no longer remember the identification of. I'm willing to take the risk of blowing a few up in the name of discovery. I consider this a learning exercise. ( plus, it's a great excuse to buy a new tool :p )...

That looks like it takes up a lot of space. I dont think it will fit on my workbench.

I recently returned to the hobby and I have a ton of un-labled mystery diodes that I want to test. I'd love to know what bench supply you are using to test your diodes. Or perhaps you can suggest a good entry level power supply in the $100-ish range ? Of course... if you have a link to...

I really like that host. How difficult is it to wire for a laser driver and keep the illuminated switch functional?

The fine internal threads appear to be CCW. ( Letfy tighty - righty loosey ) If you look closely at the picture you can see where the threads terminate at the 12 o clock position. From that point you can follow the ridge to the left and see the thread develop.

Yes. They are opposite.

I trimmed off the crimp and then tried pushing the switch out by pressing hard on the button. It didn't budge. So I tried using a pick to pull it out, but the disk the spring protrudes through broke into pieces. After the disk was gone the switch assembly slid out easily. There are extremely...

Just to double check: Your tank is actually glass and not acrylic, right?
