Hello Guys!
Maybe you don't know me but I'm here from 2010 and I was learing a lot from all of you.
Finally I decided to set up a laser company with my friends. I hope in near future we will be a bit more known brand
Special discount for Photonlexicon members comparing to Ebay price
The lenses project was made by my own. I ordered them in optics factory. Due to a great coating they were a bit pricey.
Each lens pair is 65USD + 5 USD shipping worldwide.
For larger quantity a discount will be applied
If you have any question or need more info/photos, feel free to ask
First pair is dedicated for red Mitsubishi/Oclaro diodes, 1W 520nm NDG7475 and 3,5W 445nm NDB7A75 diodes.
Second pair is dedicated for 445nm popular diodes 1 - 2,5W and also works well with NDG7475 1W 520nm.
Lenses dimensions are 12mm x 12mm and 5-7 mm thick.
Lenses are AR coated for whole visible spectrum 400 - 700nm.
Extraordinary visible light transmittance >99,7% proved with AR test shown below.
>99,3% light transmittance for whole pair!
Below there are photos with the results of measurements for several laser diodes.
Every photo was made at 10 meter distance between the wall and lenses.

I have only "after lens" shot, without lens the beam spot is almost the same as the Oclaro's one.
