Default GB Feeler - 635nm diodes and other cool stuffs

OK, reorganized. See down for individual product specs.

[/table]

5mw 635nm diodes. Kinda expensive, but as marianne and some others can testify, 635nm is an amazing colour, and is worth it.
Photo diode, common case pin is laser diode cathode and photo diode anode.
Output Power: 5.0mW typical, 7.0mW maximum.
Wavelength: 637nm typical, 645nm maximum. RED
Operating Voltage: 2.2 Volts typical
Threshold Current: 30mA typical
Operating Current: 40mA typical
Monitor Current: 0.3mA typical.
Operating Temperature: -10 to 60 deg.C.
Package: TO-18, 5.6mm diameter base.
Fits in Aixiz housings.


Surface mirrors, trapezoid shaped Aluminum mirrors, 2" at the top, 1.8" at the bottom, 1.6" tall, and .092" thick.
If I can get a minimum order of 25 the price drops by $1.

Surface mirrors, 24mm square, or 13mm x 1mm round. Only 350mg, great for scanners.

IR pass filter (acrylic), 1.18" square x .057" thick (30mm sq. x 1.4mm), Good for checking IR content of lasers by using a digital camera.

Line generating optic, ~80 degree divergence, acrylic, .50" dia. x .10" thick. (12.7mm dia. x 2.5mm)

Silicon Photodiode, make your own laser meter! (Something like, add voltmeter for VERY simple one, calibrate with KNOWN 1mw source, or add your own programmed controller)
Spectral Response: 400 to 1100 nm.
Active Area: .25" x >15"
Dimensions: .358" diameter x .13" tall.


I found a GREAT local (almost) surplus shop.

if this goes through and someone can atest that they work well on something like DDL's circuit, i will buy at LEAST 2, maybe more. since SenKats unfortunate situation, im left ordering a driver from DDL and without an LD :-[

Note these are 5, FIVE milliwatt only. And they are 635nm not 650nm, that's why they are so expensive.

20$ shipped? thats not expensive! even though i know they wont burn, and their probably not too bright, it would still be soo great to see a blue laser for myself lol

uh... not blue, red to orange. more of a very warm red. will look a LOT brighter than a regular red, but still the same end of the spectrum.

Default Re: GB Feeler - 635nm diodes

Photo's can be a bit deceiving in their color rendition. 635 is RED, not orange - at least if you ask anyone to tell you what color it is, they'll say red. HeNe lasers appear red too, and their output is at 633 nm... the chart above is a nice indication but a tad off in that respect.

At equal power a 635 nm would appear much brighter than a ~660 nm DVD diode, but the difference in color is neglible even when next to eachother.

The colour in those pictures (on my computer) don't look much like the colour of my Atlasnova 635nm .... I agree with Benm that there is little visual colour difference compared to the GB diode for instance...

Default Re: GB Feeler - 635nm diodes

Another option is AixiZ site, where they seem to have complete modules (just add current-limited power) in 635nm for:

$12 for a 5mw module
$30 for a 10mw module
$1160 for a 450mw module with power supply

or you can have 200mw of 473nm for a mere $2450

980NM 1200mw $385.00 USD << crazy powerful NIR burner?
808nm 2000mw module $455.00 USD

http://www.mfgcn.com/_wsn/page2.html

*Edit* According to some ebay auction remarks, the AixiZ 10mw modules were apparently designed for OEM applications between 5.5mw and 8mw. They may still be pushable to >10mw with proper heatsink and cooling, but they were never really designed for cw 100% duty cycle > 8mw.

Default Re: GB Feeler - 635nm diodes

I want an indigo laser... :-[ Someone hook me up with someone who can make it happen :

Oh... sorry for the OT comment... good stuff BF

Ben, I agree with you on the colors too... HeNe is not orange and it runs at 632.8nm... it's red. And with compared to a 650nm it just seems like a lighter red... or rather closer to orange, but far from orange... It's not like it'll be the same color as Florida's Natural or anything... It's actually red... a nice cool red, not as ruby red as 650/660 is though

In shows a 660 is much preferred over the 635 counterpart due to the more realism of color in it. getting a high power red with really good beam specs is hard though... and that's why DPSS 635 is a much better alternative. You'd need less power to get a more visible red, but it won't be as true as 650/660 or even 670. Although, the higher you go in the spectrum, and the closer you get to IR, the more red you'd need... and more you'd need to create an array setup, and the more you'd need to sacrifice on the beam specs The price would be about the same as a nice compact DPSS 635 in the end

Default Re: GB Feeler - 635nm diodes and other cool stuffs

635 is definitely more visible than the 660-ish output of DVD writer diodes, i think the perceptual difference in brightness is up to 10 times for equal power.

The main benefit of 660 is easily available diodes, so you can create a beam so powerful its well visible, and also has burning ability. It's too bad powerful 635 nm diodes are extremely expensive.

From the flem meet,

>400mw of 660 vs 230mw of 635




635 looks more orangy and is WAY more visible.
