Where to get a laser beam collimator that compresses a red beam from 6-8mm to 3mmAnyone knows? Links
Thanks

Any chance of getting a shorter focal length lens in the diode/lens mounting? If so you'll lose less light.
I found this one at http://www.laserfx.com/spectronika.l...om/Optics.html
scroll down the page!

Thats a nice collimator,. looks like it may work for that
Hopefully there wont be any undesirable effects to the spot size because of change of divergence..
Too bad they didnt announce the price, Buy one and let us know
Im looking at Thorlabs to qoute me on one to do the same thing.
This wouldnt be by chance a 635nm RED laser your wanting to correct?

There will always be. Probably the beam has been made so wide as to control the divergence...
There are some nice applets on the web showing "gaussian beam propagation" which applies to laser beams. Lets you play with lenses and shows how the beam propagates especially divergence.
Here is one of those applets
edit:
Try making a very thin beam and watch divergence go out of control. There was another applet that I can't find anymore that lets you set some laser parameters that determine the relation between beam diameter and divergence.

Thanks Zoof for posting that..
Thats just what I was trying to find for Cruch..
Yep, Theres always a trade-off
It all depends on what is acceptable for your application.

I was also looking for that thing. Anyone knows the price?
I hired an Italian guy to do my wires. Now they look like spaghetti!
I have sent an email same day I posted in here.
But no response yet.![]()

The response from spectronika.com. The people who actually make the thing.
laserfx is a reseller and I don't know if laserfx is in business anymore.
info(at)spectronika.com
Thank you for your inquiry.
Our collimator shrinks the beam 2-3 times. It works for wavelength 511-578 nm.
The price is 170 EUR EXW, VAT not included.
Discount for more than 10 pieces.
If you need the collimator for specific purpose, please tell so that I
can check whether it'll work and send you more details.
Best regards,

I put a request for 635nm...will see if they cam make it.
