PHR-805 405nm diodes, replace PHR-803t's

[SenKat_Stonetek]

You mean one of those carbon beam terminator thingys? Probably wouldn't be a bad idea, my shed IS wood framed - (built it myself), and hours of hot laser light hitting it might not be good - of course I wouldn't have the beam focused tight for that kind of test. Still not a bad idea....

MAKE one - don't pay for it ! GAH ! High Temp flat black rustoleum (the stuff used for grills, AND some unscrupulous people who insist on calling a spray-painted TEC a THERMAL laser sensor ! HAHAHAHAHA), and insulated metal would be perfect. Helluva lot cheaper than buying a beam terminator, JUST for testing ! GAH !!!!

That would BEE just lovely - and inexpensive....

GAH ! Coffee all over my damned laptop now, thank you VERY much ! :crackup::crackup::crackup::crackup:

The Pin out is like a LPC. Man thats weird. Is this the first blu-Ray with that kind of Pin out.?

Hi,

This pinout looks a lot like the pinout used by 405nm laser diodes used for scientific/lab laser sources... Often, the other non-case pin is a built-in photodiode for direct optical power measurement.. Can anyone with one of these do some measurements to see if there is anything connected? If so, these diodes are quite a find!

Cheers,

Pete

the photodiode should allow for active cooling if connected to a TEC or something similiar.

ok guys i've made a couple lasers with this diode and i'll tell you its real sweet. Using odicforces V2 boost driver, i can run 3XAAA nimhs and still get 110mW at 150mA current. Runs cool. very stable, no output reduction even after 3 minutes on. I think these 805's can be reliably ran to 120mW with the right lens. With the 405-g2's i have i was hitting a whooping 153mW from a PHR!!!! thats sweet. nice beam. i got pics...let me show you 110mW...i'll take some pics of it with the g2 lens later.

this diode is a winner in my book. no need for a 6x. My sf-aw210 build is not much brighter than this.

there was another member that had a mutant 803.

I do. It did 275mW till I had it turned down to 120mW. Still have it, and its still going strong.

^ . WoW TJ thats Nuts for a PHR and its still going. How old is the laser now.?

That Deserves a +1

aww shucks...I tried 220mA on another phr-805 and bammm LED'd

At least the price was right

I got about 136 hours on a PHR-805T set to 130mA. Not too bad if it had been used in a pointer, would have lasted years. The first one I tested I accidentally let the current get to 160mA instead of 140mA, at that current the diode lasted between 5-9 hours (LED'd while I was not home).

So I guess at 120mA you should really get a long life in a pointer from these diodes. I'm gonna run mine at 130mA.

Hi all,
I have 3 out 4 components to put together my phr 805t laser but I need your help.

The diode I bought was this one:
PHR-805T laser diode 405nm 100-120mW [M0025] - $9.99 : Modwerx Shop

The host/body/lens combo I bought was this one:
New Focusing Laser Host for Laser Construction (eBay item 160564459175 end time 24-Jul-11 19:54:03 AEST) : Consumer Electronics

I already have 14500 batteries. All I need is the driver/circuitry. I was wondering if you guys could help suggest me one (doesn't matter from where) that would be compantible with the above combination?

All help would be greatly appreciated

Did you contact Modwerx.... Drew will help you out...

I contacted him and this was his reply:

the flexdrive would be a great driver to use but they are out of stock right now. the host your going to be uses is made for 2 x CR2 batteries. I don’t know the specific dimensions of each battery off hand, but you may want to check to see if a 14500 fits the host. there are some 2.6-3.7v versions of the CR2 batteries you can look into and be able to use another driver.
