Advanced Focus System
With more than 200 patents, petty patents and design patents applied for, Led Lenser has revolutionised the world of flashlights like no-one before. The Advanced Focus System may well be our most important invention to-date.
The Advanced Focus System reconciles lens and reflector and makes use of the advantages of both systems while eliminating their disadvantages.
Lenses have the advantage of emitting a circular, homogeneous light beam whilst Reflectors (Concave Mirrors) can focus light over great distances.
Lenses have the disadvantage that they cannot focus light over great distances. Though they excel in collecting light, about 70% of the original LED or lamp radiation does not reach the lens.
Reflectors have the disadvantages that they project a black hole in the centre of the light cone when defocused and often don’t produce light homogeneously but in ring forms.
The development of a focusable reflector-lens, i.e. a combination of reflector and lens, is the result of our cooperation with OEC (Optics and Energy Concepts) in Munich, one of the leading light research institutes in the world.
The Advanced Focus System provides stageless transition from a broad beam to a focused spot beam whilst eliminating black spots or dark rings. With the Advanced Focus System you get a bright clear light from flood to spot – and everywhere in-between.
