The Novatac uses the same size lens as a Aleph 19 .... 22.5mm x 1mm
I know that both KD and DX sell cheap 22mm aspherical lens.
Other than that try Surplushed
I've seen a few Fenix's sold here in the past with an Aspheric lens
installed.
So I'm sure there's something out there that would fit a Novatac. I can only imagine the results on my 120P :naughty:
Tried it .... does not work with the lens I have (from DX)

I been messing about with aspherical lens in Maglites, for the best results
the reflector needs to be removed.
Also the focal distance between the emitter and the lens needs to be correct.
When this is correct the resulting beam will be a well defined square ... the
same shape as the emitter, like this
EDIT ..... The above photo is from a Mag/Aspherical setup
Methinks, this thread needs to be moved to the "Homemade" section
I managed to remove the reflector and tried it with the aspherical lens
Not very pretty is it :shakehead
The focus is way off and the Seoul emitter does not lend itself very well with
an aspherical lens ..... Crees in my experience work better.
With the reflector removed I used a spring from an SF lamp to hold the
aspherical lens in place thats why you see the bright outer rings around the
hotspot.
Notice the red tint around the hotspot ??? ..... thats the color of the heatsink :candle:
