Modifying Stock Optics Tip #3: Turn A Sphere Into An Asphere

I am looking to prototype an illumination system. My objective is to use a small halogen filament bulb and end up with a beam of light. What would be the best lens or lens combination to give me this projected spot of light?

What is the difference between the effective focal length and the back focal length?

What are the benefits of aspheric lenses compared to standard singlet lenses?
