Besides the beauty of the Kryton design by Kenom, the fact that the diode presses directly into the Kryton head gives it superb heatsinking...
I always wanted to put a Meredith glass lens into a Kryton, but did not want to drill out the head and change this quality. Besides, I like the 'flip' open aperture caps that Ken sent with the Krytons.
The answer was to simply mount the Meredtih glass lens into an AixiZ glass lens nut! Same as I did with my 405-G-1 glass lens mod for blu-ray that you may have seen here:

The Meredith glass lens is a different size than the 405-G-1 glass lens. So the drilling for the modification needed different sized bits, as well as a different size custom spacer to hold the lens inside the modified metal nut.
The result is absolutely perfect!
The Meredith glass lens is not quite as 'close focus' in design as the 405-G-1 glass lens. So I did not have to cut the spring length to get focus.
As you can see, the fit is perfect! And the 'flip' open aperture cap is still perfectly functional!
Here are the comparisons for power differences with three different lenses for this open can red build set at 452mA's: (I normally set the open can's a little lower, but with the 'direct press' design for the diode mounting in a Kryton, I think I may be ok with a little more current)
* AixiZ Acrylic - 265mW's
* AR coated acrylic from Virtual Village - 292mW's (10% increase)
* Meredith glass - 322mW's! Over 20% increase vs AixiZ acrylic!
SCHWEET!
