Optical systems for endoscopes, borescopes, dental scopes, and the like, having three groups of lenses of positive optical power and an external entrance pupil (P). Typically, all three groups are displaced from the pupil (P) and focal planes (F). The displaced groups participate in the image transfer and pupil transfer. Optical power can be shifted from one group to another, distributing and reducing the overall power requirement, and aberration correction can be shared among these groups. The first group, which conventionally has the highest optical power and associated aberrations, can thus transfer some of the aberration correction to other groups. The sharing of these optical functions results in a fully integrated optical system. The total optical power is so reduced that a line-of-sight deviating prism (2) can be accommodated between the entrance pupil and the first lens group. The resulting simplicity makes the optical system suitable as a disposable item.

Systèmes optiques conçus pour des instruments, tels que des endoscopes chirurgicaux ou dentaires, et qui possèdent trois groupes de lentilles de puissance optique positive, ainsi qu'une pupille d'entrée extérieure (P). Ces trois groupes sont normalement déplacés depuis la pupille (P) et les plans focaux (F). Ces groupes déplacés participent au transfert d'image et de pupille. La puissance optique peut être déplacée d'un groupe à l'autre, ce qui répartit et diminue la demande générale de puissance et la correction d'aberration peut être partagée entre ces groupes. Le premier groupe, qui possède normalement la puissance optique la plus élevée et les aberrations associées, peut, de ce fait, transférer une partie de la correction d'aberration vers d'autres groupes. Le partage de ces fonctions optiques permet d'obtenir un système optique totalement solidaire. La puissance optique totale est diminuée de sorte à pouvoir admettre un prisme de déviation de ligne de vision (2) entre la pupille d'entrée et le premier groupe de lentilles. Etant donné sa simplicité, ce système optique peut être un article jetable.
