Hi everyone,
I noticed something weird with my last charge of Aixiz glass lenses for 405-445nm Lasers.
The first lenses I ordered (from cajunlasers) are pretty good and I love them. Unfortunately they got a little bit dirty after some time and I also needed some for red, so I ordered new ones directly from the Aixiz Store (Of cause some for red and some for blue) But when I changed them I noticed if they are barely screwed in the housing the dot on the wall was way smaller then with my first ones... Also the "infinite focus" is some millimeter farer from the diode. But the power differences are huge. My old ones give 110mW, the new 80mw! When Im holding both lenses in light they look golden / red... The lenses for 660nm look blue, so there should be everything ok, I dont think I mixed them up...
But how can I get so huge differences with 3-Element glass lenses? :thinking:
Its almost 30%, just like my first diodes were G1 Lenses for 10 bucks....
The difference in the "focus lens gap" appears with 405nm and 445nm. Actually this was the first reason why I didn't use the new ones, because I had a way more limited focus then before, but after I measured this power differences Im a little bit confused...
Did someone ever experienced this? I mean I ordered 5 Lenses which are total crap compared to my first charge of lenses... The new lenses were definitely labeled for 405-445 nm...
