Abstract
A headlight of the type worn by medical and dental professionals includes a housing having an opening therein. A housing defines opposing ends and a passage. A light source, such as a LED, is proximate the first end. An optical assembly is in the passage of the housing and includes a first singlet lens, a second singlet lens disposed between the light source and the first singlet lens, and a third singlet lens disposed between the light source and the second singlet lens. Each of the second singlet lens and the third singlet lens are centered on the optical axis and the second singlet lens and the third singlet lens are spaced apart by a separation distance.

A headlight of a type worn by medical and dental professionals, the headlight comprising:
- a housing defining a first end opposite a second end and a passage extending between the first end and the second end;
- a light source proximate the first end;
- and
- an optical assembly at least partly in the passage of the housing, the optical assembly comprising:
- a first singlet lens proximate the second end and defining an optical axis;
- a second singlet lens disposed between the light source and the first singlet lens;
- and
- a third singlet lens disposed between the light source and the second singlet lens,
- wherein each of the second singlet lens and the third singlet lens are centered on the optical axis and the second singlet lens and the third singlet lens are spaced apart by a separation distance.

- and
- an optical assembly at least partly in the passage of the housing, the optical assembly comprising:
- a first bi-convex lens proximate the second end and defining an optical axis;
- a second bi-convex lens disposed between the light source and the first bi-convex lens;
- and
- a plano-convex lens disposed between the light source and the second bi-convex lens and the plano-convex lens is oriented with a flat optical surface facing the light source,
- wherein each of the second bi-convex lens and the plano-convex lens are centered on the optical axis.
