High quality Collimator price drop

[mccarrot]

Hi Andy

I can also supply the 11 mm collimator holders to mount the collimator.

0,5% loss on the optics is extraordinary.

The divergence is near the divergence of the diode (better is not possible)

I personally have not tested LENS27, but if lens 27 is better than this lens I will refund your money!

I think KL79 used lens27 and is now switched to this lens, so you could ask him for the differences.

you are selling these very expensive lens.

Expensive is relative, if you need to rebuild your multi diode setup due to stability issues that would be expensive.

likewise ive not used the lens27, but ive seen it being used with my own eyes and read posts about it on the forum and it is top notch.

wonder if he would post some figres for us all to see.

thanks for the info

no issues at all thanks

let say you do it right and you will end up with a 0.8 mrd 640nm beam/600mw and for let say 700 euro,s

compared to a kvant thats dirt cheap

Here,s a picture of the mount for the colimators

Here are the collimators with mount.

Mount will cost 20 euro.

Hi Evrybody On world!

If somebody want to buy colimator for opnext red 150mw diode the best is
from thorlabs
http://www.thorlabs.com/thorProduct....mber=C390TME-B

This is the best solution at the moment. u will get 1mm diameter round beam.
with perfect divergence.

Much better like lens27 type.


Have fun :Tom

Perfect fit!! I looked at the drawing and the hole is 11.2 and the mount is 12mm thick. So right on the spot.

Two of those and a pbs and it is perfect for a dual setup If needed some baseplates to build a quad oir dual with these mounts let me know. I will meet the manufacturer for these baseplates tommorow.

As you might know when beam diameter gets smaller the divergence increases. I guess the divergence of this lens will be around 1,5 mRad. For dual setups it will work, but when you have a plan ( in the future) to use a telescope its useless.

Oh and people already find my complete collimator expensive, this lens only is 72USD!
