Narrower beam from aixiz module?

Is there any drop-in replacement lens for aixiz modules that gives a red beam with a smaller diameter than usual?

I'm doing some color mixing experiments, but the difference between a green module and aixiz red is annoying - the green starts much smaller with a bit more divergence, whereas the aixiz gives a wider beam to begin with, but with less divergence.

If i want to correct this difference, is here some lens available?

I heard the high power lenses make a slightly smaller beam diameter in blu-rays. It might be the same for the high power red lenses...

How much of a difference does it make? I estimate the current green to be about 1.5-2mm diameter, and the beam from the aixiz in the order of 5-6 mm. It would be nice if it were possible to reduce the aixiz beam to about 3mm or so, with comparable divergence to that of the green.

I think you will like the lens...

But I have not measured the exact diameter of the beam. There are quite a few out there who have tried the 650-G-1. Maybe some have measured beam profile comparisons??

Dave mentions some beam comparisons in his review here:
http://laserpointerforums.com/f52/jayrobs-605-g-1-lens-ftw-46484.html

I think FireMyLaser got one for his White Fusion build, and he was making comparisons with beam profile...

RedlumX did some beam comparisons in an article here:

len27 will give you about a 1-1.5mm wide beam but the lens is £20 each

That #27 lens sounds interesting - 20 quid would still be $30, which i still think is pretty pricey for a lens... but on the other hand its not something likely to wear or break, so it can be used for future projects.

Where can i buy this lens?

You should also just talk to RedlumX first to see what he says about all of the lenses that he compared...

Because in his comparison linked above, he lists the Roithner Lens 27 beam quality as 'medium'.

medium...

he clearly didnt test it well then as its regarded as one of the best lens money can buy.
