## Abstract

An optical module includes a housing, an optical component, a first elastic member and a second elastic member. The housing has a first end, a second end and a through hole, wherein the first end is opposite to the second end. The optical component is disposed in the through hole. The optical component has a third end and a fourth end, wherein the third end is opposite to the fourth end, the third end protrudes from the first end, and the fourth end protrudes from the second end. The first elastic member is rotatably disposed on the first end and abuts against the third end. The second elastic member is rotatably disposed on the second end and abuts against the fourth end.

## Claims

### Claim 1

An optical module comprising:
a housing having a first end, a second end and a through hole, the first end being opposite to the second end;
an optical component disposed in the through hole, the optical component having a third end and a fourth end, the third end being opposite to the fourth end, the third end protruding from the first end, the fourth end protruding from the second end;
a first elastic member rotatably disposed on the first end and abutting against the third end; and
a second elastic member rotatably disposed on the second end and abutting against the fourth end to be spaced apart from the first elastic member on the housing, to push the third end of the optical component in a radial direction of the through hole via an elastic force provided by the first elastic member and to push the fourth end of the optical component in the radial direction of the through hole via an elastic force provided by the second elastic member.

### Claim 2 (depends on 1)

The optical module of claim 1, wherein the first end has a first restraining structure and the first restraining structure restrains the first elastic member on the first end.

### Claim 3 (depends on 2)

The optical module of claim 2, wherein the first restraining structure is a recess.

### Claim 4 (depends on 1)

The optical module of claim 1, wherein the second end has a second restraining structure and the second restraining structure restrains the second elastic member on the second end.

### Claim 5 (depends on 4)

The optical module of claim 4, wherein the second restraining structure is a recess.

### Claim 6 (depends on 1)

The optical module of claim 1, wherein a first contact end of the first elastic member abuts against the third end by at least one contact point.

### Claim 7 (depends on 6)

The optical module of claim 6, wherein the first contact end is V-shaped, straight or curved.

### Claim 8 (depends on 1)

The optical module of claim 1, wherein a second contact end of the second elastic member abuts against the fourth end by at least one contact point.

### Claim 9 (depends on 8)

The optical module of claim 8, wherein the second contact end is V-shaped, straight or curved.

### Claim 10 (depends on 1)

The optical module of claim 1, wherein a periphery of the housing is circular or polygonal, the through hole is circular or polygonal, and a periphery of the optical component is circular or polygonal.

### Claim 11 (depends on 1)

The optical module of claim 1, wherein the optical component is a laser emitter, a light emitting diode or a lens.
