  • Publication number: 20070236456
    Abstract: An optical navigation system having an illuminator housing and a sensor housing that are movably connected at a connection point with a connection mechanism, which may include a pivot. The illuminator housing and the sensor housing may be rotated about the connection point relative to each other so that the optical navigation system may be configured with a desired operating Z-height. The optical navigation system may also include a locking mechanism to lock the illuminator housing and the sensor housing in a predetermined fixed position after the desired operating Z-height has been selected.

  • Publication number: 20070228402
    Abstract: A method and apparatus is described for a light-emitting diode with high light output. A polymeric cup to reflect light holds a light-emitting diode chip connected to surface-mounting leads and is filled with an optically clear filter. The use of a polymeric cup allows for better bonding between the cup and the filler.

  • Publication number: 20050253058
    Abstract: An optical navigation sensor apparatus for an optical mouse includes an optical navigation sensor having an electronic chip, an aperture plate and an imaging lens integrated into a single package. The imaging lens includes a lens housing surrounding the aperture and providing a barrier to the entry of foreign matter into the aperture. In one form, the optical navigation sensor also includes a light emitting diode (LED) for illuminating a small area of a surface under the sensor and generating a reflected image that is detected by the electronic chip. In a sensor having an integral LED, an integral collimating lens is included for receiving light from the LED and focusing the light from the LED on the surface to be illuminated. The collimating lens is incorporated into a lens housing surrounding the LED and protecting the LED from exposure to foreign material.
