- the collimator lens 10 according to the embodiment of the present technology includes an opening 11, a reflecting section 12, and a condensing section 13.
- a reflecting portion 12 is formed on the inner peripheral surface of the collimator lens 10. Further, of the light incident on the collimator lens 10, the reflecting portion 12 is formed at the position where the light of the high angle component collides.
- the reflector 12 reflects the light emitted from the condenser 13 toward the condenser 13.
- the light collected in the condenser 13 is irradiated again toward the opening 11 or the reflector 12.
- Light of a low angle component is emitted toward the opening 11, and light of a high angle component is emitted toward the reflecting portion 12.
- the reflector 12 may reflect the light emitted from the condenser 13 toward the reflector 12 on the other surface.
- the reflecting portion 12 on the upper surface may reflect light toward the reflecting portion 12 on the lower surface.
- the light of the high angle component is gradually converted into the light of the low angle component. Then, the substantially parallel light 2 is emitted from the opening 11 to the outside of the collimator lens 10.
- the collimator lens 10 captures light with a high angle component, the focal length becomes short and the etendue becomes large. A small etendue is desirable in order to improve the light utilization efficiency. Therefore, the collimator lens 10 according to the present technology converts the light of the high angle component into the light of the low angle component.
- the angle at which the reflecting portion 12 reflects light can be adjusted with high accuracy.
- the collimator lens 10 can emit light with high efficiency.

Further, since the light applied to the reflecting portion 12 may reach several hundreds of watts, it is desirable that the metal film has light reflectivity and high heat resistance. For example, silver, aluminum or the like can be used for this metal film.

- the reflection part 12 transmits the blue excitation light 2 and the opening 11 also transmits the blue excitation light 2, the excitation light 2 from the excitation optical system and the excitation light 3 transmitted by the reflection part 12 are added. Since they are combined, the amount of the excitation light 2 can be increased.
