An endoscope has a distal end surface with pairs of white light lenses and ultraviolet light lenses having convex surface configurations positioned on opposite sides of an objective lens. The pairs of white light lenses and ultraviolet light lenses provide a wide area of illumination adjacent to the distal end surface of the endoscope being observed by the objective lens. A yellow light lens having a convex surface configuration is also positioned on the distal end surface of the endoscope in line with the objective lens.

An endoscope comprising: an insertion tube, the insertion tube having a flexible length; a distal tip at one end of the flexible length of the insertion tube, the distal tip having a distal end surface, the distal end surface having a circular configuration; an objective lens on the distal end surface; a white light lens on the distal end surface; an ultraviolet light lens on the distal end surface; and a yellow light lens on the distal end surface.

2. The endoscope of claim 1, further comprising: the white light lens having an exterior surface with a convex configuration.

3. The endoscope of claim 2, further comprising: the white light lens is one of two white light lenses on the distal surface; and the two white light lenses have exterior surfaces with convex configurations.

4. The endoscope of claim 3, further comprising: the distal end surface having a center line that bisects the distal end surface; and the two white light lenses are positioned on the distal end surface on opposite sides of the center line.

5. The endoscope of claim 1, further comprising: the ultraviolet light lens having an exterior surface with a convex configuration.

6. The endoscope of claim 5, further comprising: the ultraviolet light lens is one of two ultraviolet light lenses on the distal end surface; and the two ultraviolet light lenses have exterior surfaces with convex configurations.

7. The endoscope of claim 6, further comprising: the distal end surface having a center line that bisects the distal end surface; and the two ultraviolet light lenses are positioned on the distal end surface on opposite sides of the center line.

8. The endoscope of claim 1, further comprising: the yellow light lens having an exterior surface with a convex configuration.

9. The endoscope of claim 8, further comprising; the distal end surface having a center line that passes through the objective lens; and the yellow light lens is positioned on the distal end surface with the center line passing through the yellow light lens.

12. An endoscope comprising: a distal end tip of the endoscope, the distal end tip having a distal end surface, the distal end surface having a circular configuration with a center point of the circular configuration; an objective lens on the distal end surface, the objective lens being positioned off center on the distal end surface with the objective lens being spaced to a side of the center point of the circular configuration; and a pair of ultraviolet light lenses on the distal end surface, the pair of ultraviolet light lenses being positioned off center on the distal end surface with the pair of ultraviolet light lenses being spaced to one side of the center point of the circular configuration.

13. The endoscope of claim 12, further comprising: the circular configuration of the distal end surface has a center line that extends across the distal end surface and through the center point; and the objective lens and the pair of ultraviolet lenses are all positioned off center on the distal end surface and are all spaced to a same side of the center line on the distal end surface.

14. The endoscope of claim 12, further comprising: a pair of white light lenses on the distal end surface, the pair of white light lenses being positioned off center on the distal end surface with the pair of white light lenses being spaced to a side of the center point of the circular configuration.

15. The endoscope of claim 14, further comprising: the circular configuration of the distal end surface has a center line that extends across the distal end surface and through the center point; and the objective lens, the pair of ultraviolet lenses and the pair of white light lenses are all positioned off center on the distal end surface and are all spaced to a same side of the center line on the distal end surface.

16. The endoscope of claim 12, further comprising: a yellow light lens on the distal end surface, the yellow light lens being positioned off center on the distal end surface with the yellow light lens being spaced on an opposite side of the center point of the circular configuration from the objective lens.
