For red: Check out my 650-G-1 glass lens mod fit for AixiZ! See here:
http://laserpointerforums.com/f64/f...modification-fit-aixiz-25-increase-46332.html
The 405-G-1 glass lens is the most power for blu-ray or 445...
Many people will choose the AixiZ 445 glass lens for a 445 build. Because the multimode 445 diode makes a line instead of a dot. And the AixiZ 3 elment lens will 'clip' the line shorter, giving a better looking dot. (at about 15% less output power vs the 405-G-1) See lens comparisons for 445nm here:
http://laserpointerforums.com/f65/445nm-lens-comparisons-51456.html
The G2 from DTR is a few bucks cheaper than my G1 assembly, but it is not mounted the same...
That said, it's still a good set up for the price.
I spend quite a bit of extra time for the mounting of my set up, and thus, some extra cost...
I test compared the G2 vs G1 long ago before anybody knew about it, and if I had found that the G2 optic was any better in even the slightest way, then I would have switched over long ago. I was the one that tested the G2 for Will (lasers4u/laser66), and compared it with the G1. (see testing below)
Since I found no difference, I kept the same optic.
As the pictures below show, the difference is in the way the optic is mounted. Here are the main reasons that I go through the extra work for my mount:
* Able to enlarge the entry aperture and allow more light from the diode into the lens
* Able to set the lens 'lower' in the nut, so that it can get closer to the diode if needed
* The lens is perfectly centered in the nut (if just mounting it in the retaining ring end of the nut, there is a possibility that it can get off center)
As you can imagine, there is a lot more work involved with the way I mount the lens.
* Machine the lens nut to fit the diameter of the lens
* Enlarge the entry aperture
* Make the custom sleeve/retainer tube that is shown in my pictures below...
Cleaning:
One of the nice things about my assembly, is that it can be taken *apart for cleaning if ever necessary.
See picture below for the order of assembly and the lens orientation for re-assembly:
For max power, people will choose the 405-G-1...
In the case of a 12X build, just about every body uses the 405-G-1 as can be seen here in this list of 12X builds showing all components of the builds:
http://laserpointerforums.com/f38/12x-br-diodes-46798.html
These glass lenses for blu-ray are not cheap, but if you want the most increase in power vs AixiZ acrylic, this glass lens is the ticket! And worth every penny! (IMO)
It gives a 31% increase in power for blu-ray vs AixiZ acrylic. (new) Which means a 26% increase in power vs AixiZ acrylic - back opened.
Power comparisons using several different lenses for red and blu-ray shown here
This 405-G-1 glass lens is an Aspheric lens, with AR coating on both sides.
I'm not making a lot on the machine work for the modification and custom spacer. The parts are the expense.
Note: I would like to share why I chose this mounting method over other methods...
The lens will fit 'sloppy' in the AixiZ glass nut, unless it is drilled to the precise size needed for the lens. If the lens is just sitting in the retaining ring area, the remaining 'smaller diameter' of the lens nut that the top of the lens will sit against. is not fit properly, and could even chip the glass.
Not that it will happen, but it could. I am talking from experience. Yes, I chipped a lens trying it this way. This, among other reasons, is why I chose the modification that I came up with.
Even though it requires:
* Enlarging the aperture with one drill size.
* Drilling out the nut to fit the 405-G-1 glass lens sitting on a tiny 'lip'.
* Making a custom spacer to retain the lens. (my custom spacer/retainer sits on the 'rim' of the lens that is made for mounting it)
And... Not only is the barrel of the AixiZ glass lens nut too small in diameter for this mounting method, but the threaded area is too large in diameter for the O.D. of the lens. This is what I mean by fitting 'sloppy'. I guess if it was glued in place, and perfectly aligned, then it would work out. But not a good way to mount the lens. (IMHO)
On the other hand, my method also leaves room for the 'finger grip' focus ring to be installed 'all the way on', and still allow focus!

NO GLUE in my lens assembly! You won't have to worry about if it is glued in straight, or if the glue will begin to dry out or chip with heat. My lens assembly will last a lifetime. And you just may want to take it apart and clean the lens once a year!
Below are the pictures of the lens modification and results...
I am mounting the 'flat' side of the lens on the drilled out 'lip' on my assembly.
The crown side of my lens sits inside my custom spacer/retainer that is only touching the outer mounting 'rim' of the lens that is made for mounting the lens.
(Data sheet for this 405-G-1 glass lens)
I did a comparison on my Pocket Mini 6X which is set at 181mA's...
* AixiZ acrylic (back opened) - 171mW's
* 405-G-1 glass lens - 215mW's!
That is a 26% increase in power! The focused dot is very nice, as you can see in the picture. It want's to burn everything it touches...
I measured 28% more power in my 'Micro Chrome' build shown here: (vs AixiZ acrylic - back opened)
FS: Micro Chrome Build Kit! FlexDrive 'Hot' option - Laser Pointer Forums - Discuss Lasers & Laser Pointers
And Dave Guin got 28% more with his 8X build!

$55 dollars plus $3 dollars shipping. This modification includes the 405-G-1 glass lens complete assembly, with the 'finger grip' focus ring... (ready to install into your AixiZ module) You must use your existing spring, which will need to be shortened a tad. (using the spring is optional, I recommend 1 1/2 wraps of Teflon tape)
If you just want the bare lenses, I will sell them for $28 dollars plus $2 dollars shipping...
* Please read my shipping policy here!
There is a new lens in the neighborhood... (G2)
I made this thread just so there would not be any confusion with another lens being available. These are my honest findings with the power comparisons. (as everything else I share) I have two of these that I bought. They are the same price. I would gladly sell them at a couple of dollars less to anyone who also wanted to do some comparison testing!
It is the exact same optical design as the 405-G-1, but it is just from a different supplier, and has a slightly different AR coating. Same focal length, same side splash, same specs exactly...
Will (lasers4u) is calling it the 405-G-2 only because of the slightly different AR coating. (and different supplier)
He was my supplier for the 405-G-1 bare optics, and I can get these new lenses from him as well.
But I went ahead and got my latest supply of the 405-G-1 lenses direct from the manufacture because I wanted to stick with what I have had all along.
However, the new 405-G-2 is basically the same output for blu-ray. (very close)
Same pricing on the 405-G-2 as well...
New Lens Testing:
I did testing with three different lasers... (two different power blu-ray's, and a red)
GGW 6X @ 188mA's:
* 405-G-1: 234mW's
* 405-G-2: 231mW's
BDR-205 12X @ 350mA's:
* 405-G-1: 480mW's
* 405-G-2: 478mW's
LOC red @ 431mA's
* 405-G-1: 292mW's
* 405-G-2: 279mW's
* 650-G-1: 305mW's
So although it is not as good for red, it is pretty much the same for blu-ray. (within a couple of mW's)
For red, my 650-G-1 is about 5% better than the 405-G-1...
Best for red: I have this same modification using a different lens specifically for red. My 650-G-1 glass lens mod fit for AixiZ! See here:
http://laserpointerforums.com/f64/f...modification-fit-aixiz-25-increase-46332.html
Note: These are fit for AixiZ modules. If you need it to fit a Sure module, just let me know when you order. Sometimes the Sure modules are not threaded all the way down on the inside where the lens threads in. So I would machine a few of the front threads smooth, so that it fits the Sure module.
Also, the threading on Sure modules are tighter, and I need to run the lens nut through my 9mm X .5 die to take the black finish off of the lens nut for it to fit.
P.S. Just some information about Meredith... They are no longer offering their 'optimized for red' glass lens. But I have my 650-G-1 glass lens mod for red linked above!
(same power increase for red as Meredith 'optimized for red') 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 my 650-G-1 glass lens mod.
Update:
The 'side splash' is similar to the Meredith glass lenses. But the dot is very intense and wants to burn everything it touches!
(Beam shot comparison with smoke)
Here are some beam shot comparisons with 6X vs 8X. Both using my 405-G-1 glass lens modification...

This flash paper is a MUST SEE! I posted his video elsewhere, but since Chuck is using my 405-G-1 glass lens mod, I wanted to post it here... (I asked him first)
Chuck bought a 405-G-1 glass lens from me and built it into a PHR Phaser style build. This video shows his PHR instantly burning white 'flash' paper! The flash paper is really cool stuff! I bought some and it is awesome, just like this video:
Flash paper: Flash Paper Fire Magic
I bought the 2" X 3" sheets, and all you need is to tear a very small piece (like a 1" X 1" square), and roll it into a ball. If your dot is focused properly, it will 'flash' instantly, like in the video!
