I only had the one and it was sold on ebay a long time ago. Sorry.

Governments should never be allowed to outright ban products because of their potential for danger. It is the job of the PEOPLE to use those products responsibly. By letting the government control what you can and can't do over every little thing is giving the government the power to control you...

I have a few of these at work I am suppose to tear apart and do something with eventually. Maybe I'll just build myself a handheld with it. send me a PM about the power supply. I might have a need for it in the near future.

This is just a guess, but with a nicely AR coated lens made of BK7 or better yet fused silica or quartz, the reflection losses would be under 0.5%. Absorptive losses would vary on thickness but I imagine the lenses could be pretty thin, so no more than 5% loss. Then for 2 lenses you might get...

I am an optical engineer, but not by education and I don't deal directly with lens or optical system design. I mostly deal with laser systems and holography. Anyway, it would seem to me that a cylindrical lens pair would be the best way to collimate this diode. would the spot be as small as we'd...

if i had known about these diodes a few months ago I definitely would not have sold my scanpro /kicking myself/ definitely awesome set up you have FP

if you want something coated for 445, which may be hard to find as a stock part, it might be worth getting a group together to get a coating run. Thin Film Labs is a company I have had things coated from before at work and they are insanely cheap. Depends on the coating of course and how many in...

not sure on that particular pair, but I looked on the thorlabs prism pair and it looks like the input side prism is backwards actually

As usual the US let in our customary first minutes goal. I guess I have to go for Germany now. Gehen Deutschland! I don't mind the buzzing. I hardly even notice it's there and when I do it just seems to make it more live. Can't wait to be in Rio in 2014.

exactly. if a country's citizens are ignorant and afraid they are much more easily controlled. Hence why just about every country in the world with an established government is becoming less and less free by the day.

It looks like one of those TANKS grew a tail. Are they evolving too!?

Re: Photos and Video of 445nm I saw a 445 about a year ago when we ordered a unit at work to possibly replace our 457 DPSS units. The 457s are 300mW, the 445 was 300mW I think and we also got a 500mW 405 to test. I remember the 445 looking a lot more like the 405 than the 457 only a lot...

Thanks a lot aXit! Was a pleasure doing business with you. I'm open to offers on this. If no one takes it I'll put it up on ebay this weekend.

I have a pair of night vision goggles from the Modern Warfare 2 prestige pack. They're pretty cool little things. I just never use them and I need money to build a 445 laser. I will post pictures when I get home. I think I have a video I can post too. Just as a note, these are not the same as a...

payment sent! can't wait to get this together!
