## Abstract

A sterile covering for an optical device comprises a window element and a shell. The shell is attached to the window element, the shell having an opening closed by the window element. A system comprises an optical device and a sterile covering.

## Claims

### Claim 1

A system comprising an optical device and a sterile covering, wherein the sterile covering comprises a window element and a shell, wherein the shell is attached to the window element, wherein the shell has an opening closed by the window element, wherein the shell has an edge region, wherein the edge region is mounted on the window element, wherein the opening is surrounded by the edge region, wherein the opening has a smaller cross-sectional area than the window element, wherein the optical device comprises a locking element for the window element, wherein the shell and the window element are connectable by at least one of an adhesive or a welded connection, and wherein the edge region is arranged at least partially not directly adjacent to edges of the window element.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the window element is arranged above a measuring element of the optical device.

### Claim 3 (depends on 1)

The system according to claim 1, wherein a fastening adapter is mounted on opposite side edges of the window element.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the locking element includes a snap mechanism.

### Claim 5 (depends on 1)

The system according to claim 1, wherein the locking element includes an unlocking mechanism.

### Claim 6 (depends on 1)

The system according to claim 1, wherein the window element comprises an edge containing a chamfer or a rounding.

### Claim 7 (depends on 1)

The system according to claim 1, wherein the shell covers the locking element.

### Claim 8 (depends on 1)

The system according to claim 1, wherein the window element is disposed with a sterile side, and wherein the shell is attached to the sterile side.

### Claim 9 (depends on 1)

The system according to claim 1, wherein the window element comprises a first layer and a second layer.

### Claim 10 (depends on 9)

The system according to claim 9, wherein one of the first or second layers comprises an opening.

### Claim 11 (depends on 9)

The system according to claim 9, wherein the first and second layers are joined together by an adhesive bond.

### Claim 12 (depends on 1)

The system according to claim 1, wherein the window element is printed on at least one side.

### Claim 13 (depends on 3)
