hello everyone i decided to make a small and quick tutorial about all the latest diodes with gballs and how to properly focus them because i have read alot of comments from members that don't even buy or want any gball diode because tend to degrade after deccaning,well you don't have to deccan it :shhh:
1st of all sorry for the pure image quality and not any mesuring methods but the whole testing was very quick,if any further discussion and mesurments needed i can do that later.
for the testing i grabbed a nubm05 diode that was way out of focus with the original gball diode intact,this diode make a very big square box in 10 meters.
you can clearly see the box output although i captured the "dot" 2 meters from the diode.
my diode is mounted on a desktop heatsink and powered from a psu,so 1st step you just have to screw a common G2 lens BACKWARDS ( i know on the image it is not backward but i took the pic before realising that make a bad output that way)
the ring you see on the image is cut from a standard 5.6mm diode housing and i just need its m9x0.5 threading to connect the 2 lenses.
i screw the G2 lens till it hits the gball's metal frame and here is the unfocused output you get( my lens is a bit dirty i know)
this output is just like any output from diodes without a gball so now we only have to focus it as normal.
i used a 3 element lens for the testing but any lens can work as normal,even a G2 if you can stand the divergence.
simply screw the metal threaded ring and after that the 3 element lens(or any lens),it will look like this
here is the output we used to work with :bowdown: (edit:at this time i realized that i had to use the 1st lens backwards and changed it,the photo taken before i fixed it and that's why have so much splash around it)
screw in you last lens and focus it as any other diode
lastly here is the output perfectly focused,as you can see the "out of focus box" is gone and can focus your diode as normal even for burning.
it is very important to screw the G2 lens backwards else you will have some awful wings or dirty dot on your final output. hope this helps everyone that want to have gball diode focused perfectly without 1-2 months lifespan :beer:
edit: the m9x0.5 threading ring that used from standard brass housing is working but in case of a 3 element usage as 2nd lens it would be better a little longer ring due to long focal lengh of the 3 element lens it is on edge of the threads almost fully unscrewed,a little bit teflon can help for more secured and tigher threadings also.
