Update!
Hey I tested the 405-G-1 with my custom 'small aperture sleeve/retainer' and it is better than the AixiZ 405 glass lens... (IMHO)
Edit: After further testing, I still like the AixiZ 405 glass lens better for this diode...
Here's some initial pictures and results. I'll do some more comparison's later in the dark.
But it also seems to burn better at close distance with you focus it as best as possible.
More testers needed!
P.S. I tested it with blu-ray and it cleans up the dot amaizinly! It is about 10% less power that without the custom small aperture sleeve, but it is a very much improved dot. Pretty much as good as I could have hoped for...
For blu-ray, it would still be about 16% more power vs AixiZ acrylic. (back opened)
The custom 'small aperture sleeve/retainer' for the 405-G-1 cleans up the splash a lot, but in my honest opinion, I still like the look of the AixiZ 405 glass lens better with this 445 diode...
