some new correction optics ive been working on

3mm wide by 2.5-3mm high @ apeture

20mm @ 18 metres

That poor ruler.

Any information, or is this just a showroom of sorts? I assume the latter because of your censored photos?

any info?? what info would you like

the reason for the sensor is i dont want to give away me method just yet

just to confirm beam sizes -



3mm

although it looks like 4mm, its 3mm as there is a little dead beam either side

bad of you, andy. I have hidden projects and, as they are hidden, I just don't post they on a forum.. when I am free to share I post (the whole thing btw).
 
Let him brag, he's entitled to it.

well no one else knows so completely secret atthe mo.

i use an olike 445 lens and 3 different sets of corrections optics to correct the beam
 
After the o-like lens, he's probably got a pair of prisms and a beam expanding set of lenses.
Just my foolish guess.
 
My vote for spherical or aspherical lens rotated on the axis perpendicular to beam and anamorphic prisms, although I don't think Andy will say yes or no until he's ready. Also, if he had used a beam expander, wouldn't the beam diameter be expanded?

Perhaps we should all chip in and get him a new ruler? :san:

He could use telescopic optics a mirror and bend it slightly. Anyway it is a dick move to claim that you can correct the beam but not show us how.
