My new low-cost lenses

[trinh hong phuoc]

I just ordered 20 pcs-looks pretty one price is 2 usd-too cheap right you guys

$2 for all those lenses? Sounds like a pretty good deal to me!

They look like 532nm acrylic, too small in lens diameter for our multi mode beams unless they are short focal length but in your image they don't look like short focal length so our multi mode diode output could be clipped.
Have you tested those on our typical blue diodes such as N-450 and NUBM44 ?

I have tested with the pl450b 1.6 w-and the result is satisfactory sirhttps://www.facebook.com/profile.php?id=100016817520273

Yeah, I think you're right Red, the PL450B is a single mode low power diode, and these may work for that application, but I think these would probably clip the heck out of an NUBM44, not to mention that if it is acrylic, it would be melted in no time.
It looks like that lens can't be much more than 3mm or so in diameter.

yes, beam is 3mm

I can't see enough to tell if they are glass or acrylic lenses. Even if the are 532nm lenses, they make both types. It's the aperture diameter that makes them seem like 532nm lenses, but I couldn't say for sure either way.

I'd buy some of those for a couple $. I have some low powered reds I need some lenses for.

Dethlore, nice to see you again, long time no see.

Thanks Bowtie buddy! Likewise!
I've had a few large events of life the past couple years that have limited me to only reading a posts here and there... finally graduated, changed jobs, then changed again and moved north, selling house, buying house.... still going, but I think I can actually start working on some of my projects again!!!
