Hey Greg...
I saw your post about making it with a dog.... :o
Perhaps it's not me that's sick... :-/ :-/ :-/ :-/

Thats not cool. And please don't start fights and childish nonsense in someone else's thread.

PRICE WENT UP ON C-MOUNT GRAB BAG, since i will be adding 500mW red's and IR diodes up to 3W in it!!

$100.00 C-mount Lot of 20 C-mount diodes in a nice gel pac tray, you will get an assortment of wavelengths, mostly near IR, some red too. Possible wavelengths are all over the map, from 635nm through 1500nm. About 80% are working- Power levels are generally over a watt!

Red 655nm PULSED

May i ask if you have a circuit which can pulse this diode(+datasheet ?)? i was wondering using an old 555 timer...

if not, no problem ;) thanks
 
Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

Use a 555 and pulse no more than 100uS at 5.5A peak using a mosfet w/ freewheeling diode and balancing resistor. Diode has an intrinsic resistance of about 0.25 ohm and has a voltage drop of about 2.4V Alternately you can run at 500mW to 1w CW if cooled with a TEC to about 10 degC

Hey Chris... thanks... PP payment sent... ;)

Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

I have received first package of two today. I am very happy with delivery.

Not only that diodes were SEALED!! in anti static packing , but each comes with a little jumper over pins that shorts grnd. and positive pins, as well as protects them from breaking during shipment.

interesting note, 635nm 9mm is a very short open can 9mm diode!!! very curious.

i received a bag of "goodies" as bonus and two lolly pops - chocolate!" :-)

paperwork was included with instructions and diode ratings, and suggestions for power supply.

very nice!

Thanks
Now i am waiting for multi mode colimators and some extra time to start experiments.

thanks a lot Chris, I'm looking forward to dealing with you again, soon.

cheers

Hi

have you got the 2 watt 808nm diodes yet if you have what is the operating current and voltage so i can get ready my power supply . i orderd some through ebay too, along with a grab bag and a 3 watt diode

hope to get mine soon to :)
 
Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

for 2W diode I only got small slip stating:

2W HP 808nm DIODE
RED DOT (referring to mark by the pin for +) 2.8 to 3V at 1.5A

Chris --
What is the diameter of the collimator assemblies?
 
Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

Collimator assemblies have a beam acceptance diameter of 1/4 inch, They ARE NOT HEASINK UNITS FOR THE DIODES, you need to buy or build a 9mm heatsink. I found that drilling a hole in a piece of aluminum L rail to hold the diode in and using another piece to hold the lens works very nicely though.

i plan to place 9mm diodes in Meredith module with single glass focusing lens. Do I need to have this lens and focus the diode prior your collimating assembl?, or  post?

here is picture of meredith module with focusing lens http://www.mi-lasers.com/cgi-bin/shopper.cgi?preadd=action&key=LDC-2

thanks
 
Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

These work fine, get the 3-element lens to go with it for best results :o)
 
Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP

so i will just focus your 9mm diode with meredith lens to about less than 1/4" size (line/rectangular projecton) into your collimator to get round shaped long range beam?
 
Re: RED & 808nm 1-5 WATT LASER DIODES & MORE CHEAP

Chris, I received my C-mount grab-bag today! Thanks so much!

(And thanks for the lollipops...)
