Slipstream;
High Numeric Aperture (NA) lenses are required to capture the light from a laser diode before it spreads out.
Anti-Reflective (AR) coatings keep the light from reflecting back from the surface of the lens.
Aspherical lens design does a better job of focusing the beam (collimation).
These qualities are what increases the power transmission and beam quality of the lens.
They also increase the cost of the lens.
The good thing is that they will add power thru many diode upgrades.
