## Abstract

In order to fix an optical fiber to a desired position in a holding member easily and tightly, provided is an optical collimator (10) having a plastic optical fiber (13) and a cylindrical holder (11). The holder (11) is configured to hold a collimator lens (12) at an end and has an insertion hole (11a) at an opposite end for inserting the plastic optical fiber (13). The plastic optical fiber (13) is sandwiched by an inner surface of a recess (11e) which is formed at a part of the holder (11) in proper alignment with the collimator lens (12).

## Claims

### Claim 1

An optical collimator comprising: a plastic optical fiber; and a cylindrical holding member which is configured to hold a collimator lens at an end and has an insertion hole at an opposite end for inserting the plastic optical fiber, wherein the plastic optical fiber is sandwiched by an inner surface of a recess which is formed at a part of the holding member in proper alignment with the collimator lens.

### Claim 2 (depends on 1)

The optical collimator according to claim 1, wherein the holding member is made of a metal material.

### Claim 3 (depends on 2)

The optical collimator according to claim 2, wherein the recess comprises a plurality of recesses which is formed on one circumference of the holding member.

### Claim 4 (depends on 3)

The optical collimator according to claim 3, wherein the recesses are provided in proximity to an end of a collimator lens side of the holding member.

### Claim 5 (depends on 3)

The optical collimator according to claim 3, wherein the recesses are provided in proximity of an end of an insertion hole side of the holding member.

### Claim 6 (depends on 1)

The optical collimator according to claim 1, wherein the recess comprises a plurality of recesses formed collinearly along an insertion direction of the plastic optical fiber.

### Claim 7 (depends on 1, 2, 3, 4, 5, 6)

An optical connector for connecting the optical collimator according to any one of claims 1 to 6.
