Apparently. Look at the reading on the PSU http://laserpointerforums.com/f65/osram-pl450-450nm-80mw-power-chart-71645.html#post1031770

I am offering 3 lasers from my latest build. First I'll get to the bottom line. If you want more details check at the end of the post. There are 3 of these, labeled A, B and C. Each has built the same way and you can see from the pictures the nature of the build (details at the end of the...

Thanks DTR. Once I get the bench supply I will better be able to diagnose the problem(s). I didnt run the diode off clips except when measuring the in-circuit current. Then I used clips (good ones) but I get your point. The problems existed before that and were consistent after that too. so...

Thanks for your suggestions, guys. The reason this is confusing me is that I have a single mode laser I got from Lazerer that is outputting about 280mW and I actually built my own labby using a PL450B and a labby driver that is also doing 280mW. I am pretty sure I set it at 350mA. I decided I...

yes. when i measure the "current" on the test load I am using volts on the meter across the 1 ohm resistor and setting it 0.350V which corresponds to 350mA.

I am trying to get a PL450B single mode build happening. I am using a Microboost. did the usual things: set my dummy load to 8 diodes (~6V drop), connected the driver to the load and battery (18650). measured the current on the load (1ohm) and set it to 350mA. of course solder blobbed the driver...

Just something I've been working on...

lol hey info is info :)

Did you ever solve this?

Hi Blord. I can ship it to Belgium via air mail for an additional $5. so $60US.

Here is something a little unusual. This is a PL520 520nm green laser diode pressed into a copper module with an acrylic lens for $50. This is a DTR diode module, that he sells for $79. so why only $50 - there is a problem, jim. Below are beam shots of the raw beam out of the diode. The other...

Yeah I have a couple of these I got from Cajun. I havent used them yet though.

Re: Pre-Sale: The MSV5 HyperSticks - Custom Copperhead Hosts‏ These hosts look ideal to me. can't wait to get them and do a build befitting their near perfection.

Good to know. I thought the voltage drop was 1.2V. well, i had the right idea... lol :)

Each diode has a voltage drop of about 1.2V. the first diode is always in the circuit. so for each jumper location, multiply by 1.2 for the total voltage the load will drop across the driver. so you need to know the voltage drop across the laser diode you intend to use. you can find that in the...

yes thats how i see it. also could tell the difference in the beam in fog. love the colour.

I just got a PL520 build and wanted to chime in with a perspective on colour difference. I absolutely see a difference compared to 532. in fact I was very surprised. with 520 and 532 shining a dot on a white wall, 532 looks more yellow than 520. in other words 520 is more green than 532 and to...

What do you like about yours? Mine... I just love the idea of a vintage flashlight being brought up to date. and when I need a thrower, I grab the Jayrob Vintage. it's my only thrower. I do wish it was more weatherproof because I'd love to take it on canoe trips. But I just don't want to risk it...

Re: FS: 520 Green in SS Aurora Host NEW INFO Dont know why this wasnt jumped on. but good for me :evil: thanks for the vote of confidence ped

Don't be sad
