new lens

[curious]

where can i buy new lenses for my laser ?
the supplier asks 20 dollar ?
who knows alternative ?

[Rodney Gold]

You think $20 is too expensive?????

[curious]

for little piece of plastic ,size of a coin ?
yes i think its not in relation with the value
or what is so really special ?

[Rodney Gold]

The laser lenses are Zinc Selenium and are coated , not plastic , $20 is cheap , most mainstream laser makers ask $100+ up to $500 for a 15-20mm diameter optic

I'm with Rodney on this one, $20 lenses... Post the link please lol. I bought mine on ebay, from a little country, I never heard of. I can't even remember who now. I paid $85 and that was the cheapest I could find. Also be very careful these lenses will shatter from a 2" drop, like a plate glass window dropped from 10 stories. They are EXTREMELY delicate.

I was actually more interested in the more expensive link for lenses!~


Although just post em all. that would be coolness

i am agree with Rodney。
if you buy some imported from usa 26,the price will be more.

short update
ive got now several offers ,too much to post.
but as i understand there are 2 variations import material and normal chinese lens
prices are all around 30 dollar and for the import app 40 dollar. excl shipment.
so now i will buy both variations to see the quality difference.

[vivinar]

different materials about the lens had the different price.
Like the material is Znse 20 diameter is around USD58
If the material is Si, the price is USD33
If it is made of glass or Mu is much cheaper,but the quality is not good
We always sold like this.
