Diode lenses
To get the above beam specs a 2mm EFL diode lens is needed.
These lenses can be bought directly from DAVE at Laser Show Parts for 40$ PLUS international postage or in this GB for 37$ and will ship with your other lenses at no other costs

Where to get the Mitsubishi 300mW 635 Diodes (ML520G71)
https://sites.google.com/site/dtrlpf/home/diodes/mitsubishi-635nm-300mw-diodes
This is a Web store ran by DTR a very good seller with super fast shipping times remember to tell him kiyoukan sent you.

Setup and other information
To correct the diode you are looking at 84$ worth of optics plus shipping.
The methods shown above use vertically stacked lasers beams knife edged, Then sent into correction optics.
The nearfeild beam will be 4mm square with a Divergence of 1.05 mRad
Dual diode setups driven at 750ma, output around 1W
Quad diode setups driven at 750ma, output around 2W
These diodes can be driven harder for more power they are similar to the 445nm diodes in that they are very strong diodes and when over driven instead of just dieing they will start to dim. most of the time they come back to life and you know to turn the current down

Adjustable mounts
I am getting some adjustable mounts made for holding the mirrors.
View attachment 31105
These would be made from 6061 aluminum and have m2 0.4 threads
Price: 12$ if order total is 50 or 9$ a unit in an order of 100
The lead time to get them made would be around 18 days.
Already tested version of this mount can be found here

For those who want these made of brass that is an option and will be voted on.
Brass is more expensive so cost is higher.
Also The thermal expansion of brass is similar to that of aluminum, however aluminum / 6061 has a higher thermal conductivity.
This means if you set your lasers at 70F the brass will stay solid at higher temp's and cooler temps, if your projector is temp stabilized (not able to go over 110f or under 42f) this will not be much of a issue. were talking maybe 1mm at around 20 meters if you have some crazy temp.
When setting any mount you should run your projector to make sure the base plate is at normal operating temp then tune the adjustable mounts.
So if you pull your projector out of a freezer it might take a few min of running for it to warm back up and back to alignment.

How is bhwollen on that list?

This is a cross post from PL.
The main thread is over there.
So he was over there why did he get banned?

Oh lol.

He's banned for scamming fools

well i hold nothing against him we need every member we can. we tried for a set of 50 but failed so now we are trying for 25 and its still very hard, you want a set?

When do you want to have the GB completed?
I'm just about to order my first Mitsubishi 635 diode

Soon as in i might just scrap the GB if we dont meet 25 and buy my set along with a few others to help pay the shipping.
To get a set of correction optics from edmunds is over 100$ so buy it now and buy it fast for these will be the last.

bump only need 4 more sets till we are a go.

Okay well we have our MOQ filled now anything more is just gravy, last chance to get these.
I will not be running another one so if you want to correct this diode with the best results and stable setup this is your last chance. (if you dont want to spend well over 180$ for edmund optic lenses)

If I were to get a set of the optics plus a set of mounts, how much would that be total at this point in the GB? I may get these and build a nice labby

Actually if it's not too late, please count me in for a set of the optics and the mounts. Thanks!

Okay i have you marked down.
So you want 1 set of cylindrical correction lenses plus the 2mm FL diode lens.
And how many mirror mounts?
just 1?

How ever many mounts I'll need to install these lenses

Will these lenses work with the 500mW version of this diode?

Well for a dual a setup like this can be done that only needs 1 mount

They mounts are used to knife edge the mirrors.
They will correct the 500mw diode will the beam specs be 100% the same i cannot say.

I'll take one mount then. I figure if these optics work good for the 500mW version of these diodes, then two diodes should be more than enough

Hopefully I'll be able to find out if anyone has done testing on these optics with the 500mW diodes.
