Re: FS: >80mW Blu-Rays, two models: $185
Igor, I hope your special coated glass lenses put out even more than the Meredith glass lenses with the blu-rays!
But I would like to point out, that I believe the reason for the Meredith glass increase in power, is mostly due to the 'short focus' design of the lens. The Meredith glass lens must be positioned very close to the LD in order to get focus. Because of this, more light goes into the lens. (before it has a chance to 'fan out' inside the module)
The trade off, is that it doesn't focus 'super tight' like the acrylic lenses. (which are not as 'short focus' in design)
Anyway, looking forward to your special lenses. Keep up the great work there! I need to try to get one from you for comparisons.

Edit: Schweet! Because of your testing the different lens coatings and stuff, it got me testing my 2 X build. It has a Meredith acrylic lens.
I have it set at 110mA's.
With the Meredith acrylic lens (which is AR coated), I only get 63.2mW's.
But since the lens size is the same as the clear, non-coated AixiZ acrylic lens (after removing it from the black plastic), I put an AixiZ acrylic lens into the Meredith module....
Just by swapping lenses, it now reads 94.9mW!
Very interesting how much differences there are between lenses with the blu-rays... With the high power reds, these two acrylic lenses will give you very close to the same power.
IgorT said:Once again it turns out i might have been too conservative with the expected powers..
A PHR-803T diode can reach 117mW at only 90mA with a Meredith lens, as shown by Jayrob in his awesome MXDL builds! He mentioned a 30% increase before, but i never imagined this! It's almost 50% more!
This means that overdriving will NOT be necessary to reach >100mW with the 405nm AR coated glass lenses.. Even 90mA will have an amazing power, never mind 98mA..
This is great! I've never been this excited in my life! ;D Can't wait to get the custom lenses.
It would be amazing to reach that kind of power safely.. Even more amazing if the 405nm coating could increase it a bit.
Cross your fingers and hope for the best! Some prayers might be in order as well..
