## Abstract

This invention describes an ergonomic combination sight for small arms. According to one embodiment, the combination sight comprises a reflector sight mounted on top of a telescopic sight. A refracting wedge prism is included in the optical layout of the telescopic sight to tilt the viewing axis of the telescopic sight towards the viewing axis of the reflector sight. This feature provides better ergonomics since a shooter can aim through the reflector sight or the telescopic sight using the same head position.

## Claims

### Claim 1

A combination sight for designating a weapon's point of aim when pointed at a target, comprising:
a. a telescopic sight; said telescopic sight comprising an objective lens, and an eyepiece lens; said telescopic sight having a first aiming axis and a first viewing axis, said eyepiece lens having an optical axis;
b. a reflector sight; said reflector sight having a second aiming axis and a second viewing axis; said reflector sight being mounted on top of said telescopic sight such that said second aiming axis is substantially parallel to said first aiming axis,
c. a refractive wedge prism, said refractive wedge prism having an apex and a base; said refractive wedge prism being positioned on the eyepiece optical axis; said refractive wedge prism being positioned after said eyepiece lens; said refractive wedge prism being mounted with its base pointing upwards such that it tilts said first viewing axis towards said second viewing axis;
whereby a shooter can aim through said telescopic sight and said reflector sight using the same head position.

### Claim 2 (depends on 1)

The combination sight of claim 1 wherein said reflector sight is comprised of a red dot sight.

### Claim 3 (depends on 1)

The combination sight of claim 1 wherein said reflector sight is comprised of a holographic sight.

### Claim 4 (depends on 1)

The combination sight of claim 1 wherein said refractive wedge prism is achromatic.
