Greg asked me to do some power comparisons on three lenses that he has (and/or will have) available at his store:
StoneTek Electronics, Your Laser Parts Store
All three of the lenses are AixiZ lenses...
1. The AixiZ acrylic lens. (the back was cut opened for these power comparisons)
2. The AixiZ glass lens.
3. The AixiZ 405 glass lens.
I also added to the comparisons, my 405-G-1 glass lens modification for the blu-ray comparison. And my new 650-G-1 glass lens modification 'fit for AixiZ' for the red comparison.
Note: I have noticed that the newer AixiZ acrylic lenses already have the back opened...
'New' AixiZ acrylic 'un-opened' vs AixiZ acrylic with 'back opened':
I compared the difference in power for a 'New' AixiZ acrylic (un-opened back), against an AixiZ acrylic lens with the 'back opened'...
Power comparisons with red, as well as blu-ray:
Long open can red at 431mA's: (5% difference)
* 'New' AixiZ acrylic (un-opened) - 240mW's
* AixiZ acrylic (back opened) - 252mW's
PHR at 125mA's: (5% difference)
* 'New' AixiZ acrylic (un-opened) - 101mW's
* AixiZ acrylic (back opened) - 106mW's
5% is a considerable difference! This is why it should be noted whether or not the AixiZ acrylic lens has the back opened or not when making lens/power comparisons.
Power Measurements:
The two lasers used are an LPC-815 red build set at 431mA's, and a PHR-803T blu-ray build set at 125mA's...
(both using FlexDrives with a single 14500 supply)
Meter used - My Coherent PowerMax 5200 with PM3 thermal head.
Here are the comparison numbers:
LPC red at 431mA's:
* AixiZ acrylic (back opened) - 250mW's
* AixiZ glass - 257mW's (3% increase over AixiZ acrylic with back opened)
* AixiZ 405 glass - 237mW's (obviously not good for red)
* Meredith glass lens mod fit for AixiZ - 301mW's (note: no longer available)
* 650-G-1 glass lens mod (fit for AixiZ) - 301mW's (20% increase for red vs AixiZ acrylic - back opened) See here!
PHR blu-ray at 125mA's:
* AixiZ acrylic (back opened) - 122mW's
* AixiZ glass - 111mW's (obviously not good for blu-ray)
* AixiZ 405 glass - 128mW's (5% increase over AixiZ acrylic with back opened - nice round dot)
* 405-G-1 glass lens mod - 153mW's (26% increase over AixiZ acrylic with back opened)
The AixiZ lenses still continue to be the 'best bang for the buck'. And although their new 405 glass lens does not increase the blu-ray power by a whole lot, it does give an increase in power. And the dot is nice and round.
There is a new lens in the neighborhood...
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.
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...
