Re: FS: 405-G-1 Glass Lens Mod-28% Increase vs Aix
Nice!
Yes, the
405-G-1 glass lens will increase the power of red builds too...
Much better than AixiZ glass, but not as good as Meredith glass.
Here are my comparisons for several different lenses with both
red and
blu-ray that I copied form another post:
Note: All comparisons to AixiZ acrylic is with the 'back opened'.
Starting with the comparison of the
405-G-1 glass lens vs Meredith glass with
red. Using my 'Ice Box' TEC cooled open can build which is set at
450mA's.
*
405-G-1 glass lens - 302mW's.
* Meredith glass lens -
316mW's!
Meredith glass lens mod fit for
AixiZ here:

That's about a 5% increase using the Meredith glass lens for
red. (vs the 405 lens)
Now to be fair, using these two glass lenses in comparison with a
blu-ray build is not even close. The
405-G-1 glass lens will give 18% more power vs Meredith glass, and at least 26% increase vs AixiZ acrylic!

Edit: Just to note that the manufacturer of the
405-G-1 glass lenses does offer different AR coatings for this same optic. Here is the 'full' data sheet for the
405-G-1 glass lens that I am getting:
(Data sheet for this
405-G-1 glass lens)
Both of these glass lenses are much better than acrylic for
red as well as
blu-ray. For
red, comparing to AixiZ acrylic, you will get at least 20% more power using Meredith glass.
Other comparisons including AixiZ glass:
Compared to AixiZ acrylic (back opened), I get only 4 to 5% more with AixiZ glass for
red. AixiZ glass has 3 elements. This is why it has less gain than the other 'single element' glass lenses, even though it is AR coated for red. Plus, AixiZ glass in not as 'short focus' in design.
Comparisons: (
red open can)
AixiZ acrylic vs AixiZ glass - Gain 4 to 5%
AixiZ acrylic vs AR coated acrylic from Virtual Village - Gain 10%
AixiZ acrylic vs Meredith acrylic - No gain, or very minimal gain
AixiZ acrylic vs Meredith glass -
Gain about 20%
AixiZ acrylic vs
405-G-1 glass lens - Gain about 15%
(New broad band glass lens from Meredith - About 2 or 3% less than their 'optimized for red' glass lens with red)
Comparisons: (
blu-ray)
AixiZ acrylic vs 405-G-1 glass - Gain 26 to 28%
Meredith glass vs 405-G-1 glass - Gain 18%
AixiZ acrylic vs AixiZ glass - 7% less with AixiZ glass for blu-ray
(New broad band glass lens from Meredith - About 3 or 4% less vs my
405-G-1 glass lens with blu-ray)
P.S. For Meredith, there are two different glass lenses available now. I have tried both of them. I use the best one for
red with my Meredith glass fit for AixiZ mod. Their new 405 coated lens is a broad band coating that is decent for both red and blu-ray. But not as good as the
405-G-1 glass lens for blu-ray, and not as good as their original 'optimized for red' lens that I am using for my Meredith/AixiZ mod for
red.
P.S. I believe Meredith will be replacing their 'optimized for red' glass lens, with their new broad band glass lens.
;D
