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

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

Are the o-like lens 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.

wel they focus the raw beam from the diode.

405nm laser /445nm laser collimation lens/glasses lens on eBay (end time 27-Feb-11 14:21:14 GMT)

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.
