Sorry, Im pulling out of this gb. Hope its not a problem. I ordered a 4x squeeze set. I hope to use it in combination with my 3x and 2x squeeze cylindric lenses from OPT Lasers.

Fair. Time is money too :-) Thank you!

He last posted about this nearly 20 days ago. Thats why I'm bringing it up.

Any word on the 6x availability, or this is a dead end source? thanks

Here is the output beam of the 9x squeeze achieved with the two 3x lenses both facing forward ( like my original setup from the last page) The OPT Lasers square lens's sides are 12mm and the beam width measures pretty much exactly 4mm. I will take same photo again with the latest setup. I...

Here is my newly anodized machine work. It will fit the Stingray 3 in front perfectly and contain the best set of lenses i can find.

Here is my new 9x setup. I found that putting the two 3x lenses back to back ( flat sides up agains each other) creates much cleaner line. Day and night comparing to putting them one in front of the other facing same direction like i posted in photos earlier. So much cleaner for measuring...

Its not 9x, 18x expander. Its squeeze. We are reducing the width of the generated line, right? The exit beam of the 9x squeeze lens assembly is 4mm. I will post photos of my new setup very soon. Hopefully tonight. I took a nice shot of the exit beam diameter as well where you will see it is...

I have been way too busy lately and not much time for lasers. Thanks for keeping the thread alive. Yes, Mateusz replied the same evening. He did design these 3x and 2x cylindrical lenses for their specific project and later decided to make more and sell. They can cut them and modify them in...

You mean just build a three lens set with two 3x PCV like set on my photo? He has not done that yet. I actually emailed him today, so I'll let you know.

All this can be easily inserted into the correct size assembly tube you can machine to just fit the square lenses. They can't move but can only rotate for beam orientation matching to diode position. I'm using double sided scotch tape stuck to the steal machinist ruler to keep them in...

Here is the setup with two 3x lenses back to back producing theoretically an 9x squeeze of the final projected line (beam). This is what i originally bought from OPT Lasers. The distance between anamorphic lens pair and the final plano-convex lens is about 2.5mm. I am still playing with this...

definitely. My guess is 12x will be best. I have tested 9x and 18x so far with varying results.

3x following the 6x can be a 3 lens setup. The 3x, and the 6x can be back to back, followed by properly distanced plano-convex lens. Ill try to finaly post pics of such tests in my thread tonight.

First I'll start with diode output after G2 lens. This image is taken at 10m at about 450mW The main line is 110cm long. However if you look closely on the left edge, you'll see it isn't so solid. Now here is at 15 meters and the line is now 17cm long. You can see that the left edge has...

As I promised, am starting a new thread on this subject because i'll have a lot of stuff to post and don't want to pollute other threads. I now have mostly OPT Lasers lenses, but will try others if I get them to compare. I gotta say that guys at OPT Lasers have been super friendly and happy...

Hello, You don't need to place two consecutive sets to achieve higher squeeze ratio with multiple lenses. Multiple cylindric lenses can be placed in front of each other and than on the end a single plano convex. I can't seem to find time to post my tests and some photos of multiple cylindric...

from OPT Lasers page: "An antireflective coating is applied to both surfaces of lens providing extraordinary light transmittance of >99,7 % for the whole 400nm - 700nm spectrum."

Interesting, My 2x and 3x lenses from OPT lasers always seem to have best separation at about 25mm +/-0.5mm even if I double them up creating 6x, 9x or even 18x squeeze! Mateusz from OPT lasers helped me get the last 2x lens for lower cost so I can continue my tests and hopefully come up with...

Ill take one set.
