2 Collimating Lens Focusing Lens 7mm for Laser Diodes | eBay

The lenses arrived damaged with
fingerprints. After a bit of
correspondence, the seller eventually gave
a refund. The moral is to be careful who
you buy optics from. Ask some questions
before pulling the trigger.

One dollar lens from obscure chinese seller?

Kol'ko para tol'ko muzike
[roughly: you get what you pay for]

Sorry to hear you had bad luck, but honestly, I'm not too sure you can even blame the seller for getting dirty and scratched lenses for a dollar and a half a piece (shipping included). As enthusiasts of a specialized field in high-tech gadgetry such as lasers, it's kinda-sorta out own duty for recognizing good and bad deals.

I've been avoiding all of those soft lenses and now, China sellers except Techhood.
