An optical mouse operated with respect to an illuminated surface outside the optical mouse is provided. The optical mouse includes a light source configured to emit a light beam, and a light pipe including a first optical element and a second optical element. The light beam enters the light pipe through the first optical element, and then propagates in the light pipe from the first optical element to the second optical element without reflection, and then leaves the light pipe through the second optical element, and then illuminates the illuminated surface. The light pipe does not have any protrusion extending therefrom and attached to a front surface of the light source.

Optical mouse and light pipe thereof

There is provided an optical navigation module including an optical package and a light reflective element. The optical package includes an image sensor which has a sensor surface. The light reflective element is configured to reflect light propagating parallel to the sensor surface to light propagating perpendicular to the sensor surface to impinge on the sensor surface thereby performing the lateral detection.
