I know lasershowparts.com sells an entire mitsubishi correction kit and Drlava at (some point or maybe even still?) sells correction optics other then just a lens for correcting a red 638nm diode.
But what vendors/options are out there?
I'm 100% sure it's listed somewhere but the red holy grail topic is humongous and it seems kinda spread around.. maybe I just suck at looking though :D
I haven't seen that website; thanks for the link. I'm also interested in obtaining some correction lenses. I have been wanting to upgrade my current projector and build a couple more using 100% direct diode lasers but I don't feel like experimenting with different diodes and optics. I'm still waiting for a combination that will have suitable power, a low minimum lasing threshold, and a dot on the wall comparable to a DPSS or old open can 650nm diode. Does anyone have any real world experience to share? I'm interested power levels under 1W total for white.
http://optlasers.com/en/laser-module...h-75v-psu.html Looks like a good deal. f they had added two more reds it would be really nice
Pretty sure that module only has correction on the red and nothing on the blue or green. It is pretty but surprised they wouldn't have pulled the green and blue back a bit and added lens to tighten it up.Quote:

I still have a few set of x6 cyl. lenses, available for 45€.
They have specific coating for RED 600-700 nm (or BLUE 420-480 nm), 40-20 scratch-dig.
There's also some sets of x4 cyl. lenses, perfect for green and blue waiting to find a new owner :).
PS : a divergence as low as 0.6-0.7 mrad with 6 mm FL lens has been reached with NDG7475 or NDB7875 diodes :cool:
i also just ordered a set of these i have no idea what they are 3x 4x 6x ect
but i will say the look very small i haven't unwrapped them yet but in the tissue paper they look tiny almost unusably so

What is the difference between the cylindrical lenses of the 520 and 638nm one? I thought they were the same because they have the same beam profile.. or close to
Only the coating?
Would be cost efficient to pbs the 520 and 638 and then correct.
Where is the correction on the green and blue in this?Quote:

I highly suggest purchasing cyls from reliable sources like Dave's laser show parts.
The price of these is low cost which is good.. Let me know if they work for you.Quote:

have you checked out robs web site (stanwax) he sells a range of correction optics. ive used and will be using them again in the future
I have stacks of 4x and in a week or 2 there will be a 6x option ;-)
Personally find the 6x a better option and if you stocking them soon Dave Ill get any through you.Quote:

Total area on the Goldenstar plate is smaller than a sheet of notebook paper.Quote:
