No they are not the same person. He did sell me RT laser though. I know others have purchased from him, he made a good handful of lasers for people on here last year.

The weird thing is I have texted him, emailed him at work almost once or twice a week for probably the first 4 months then just sporadically till now. I really don't care about the 3.5w 445 all I really want is my 405 and pl520. Just sucks I'm out like $400

Hello, it has been long over due on this, but almost a year ago I purchased a mx 3.5w laser from Taylor. After receiving it the laser ended up having something burned on the diode glass. Long story short two days later diode dies. So I send it back along with a bdr 16x diode with driver and...

Bump! Do you want a tutorial and do I need to make another thread?

I really hope more people will see this so everyone can have a beam expander.

Yeah I would say so. It really shines at a distance (obviously lol), I was just surprised at the vast difference in the two dot profiles at about 70 yards. :D For $17 you really can't beat it and it was so easy!

Imgur: The most awesome images on the Internet Imgur: The most awesome images on the Internet First one is G7 lens at 31 feet second is with beam expander at 31 feet.

Would anyone be interested in me putting together a step by step on how I assembled this?

Imgur: The most awesome images on the Internet Imgur: The most awesome images on the Internet Really having trouble getting a good shot but you can kinda see.

Thank you for your gratitude! I used no glue and only used what I purchased it all came together nicely the mounting is an issue though. For around 17 bucks and some tinkering anyone can make this into a working adjustable beam expander! How do I post pics?

So at 31 feet with 3 element lenses we get a "dot" of 50mm. With the beam expander we get a more perfect dot of 20mm. Can't take a picture of the dot with calipers in frame since I have to hold the beam expander in place.

Thank you for your reply I have studied your posts and followed them for some time now and yes you are right. I guess my main point of this was to give people a project and a cheap alternative for a beam expander. I took apart the telephoto lens and had to take two plano-convex and one big...

Alright the optics I ordered arrived and I must say that this 12x telephoto lens does really work well at reducing the divergence I will post numbers in a little while, but the output is greatly reduced. I will try to remove the third lens inside to see if that helps but as a cheap beam expander...

It never really becomes an obvious line from the distance I have seen it becomes more or less a squarish circle at about 30 feet. The strange phenomenon I have been wondering about is the beam coming out of the expander seems to be split in half with two square beams on top of one another idk if...

I think it is a combination of the black coating on one of the lenses and internal reflection that produces the circle.

Well I haven't gotten around to measuring the focal length of the biconcave lens since I didn't have pins to cast a shadow and draw a line and blah blah but the plano convex is 4mm focal length. I am waiting for my other lenses to come in the mail at the moment to make a more usable beam...

I am pretty sure all but one of the lenses are glass. This really was just a silly quick throw together project with no math calculations for focal lengths or lens spacing. There is some beam clipping in my design but it almost makes the oclaro 700 diode a perfect circle.

Thank you very much. I have been working and haven't had time to come and fix that. I'm going to try a combo of this and a telephoto lens for a keplerian expander with a relay.

So I picked up a universal cell phone camera lens pack and thought I might try my hand at making a proof of concept beam expander. To my surprise everything in that pack worked to make one and no outside materials were used. <http://imgur.com/FAcv9sg> <http://imgur.com/tyXQdqJ>...
