Reducing dust contamination in optical mice |
摘要 |
Reduction of dust contamination in optical mice. Trapped charged particles within an optical element result in a surface charge on the optical element, the surface charge reducing the attraction of dust to the optical surface. Charged particles may be trapped in the optical element, or in a coating on the element. Irradiation from an alpha source or ion implantation techniques may be used.
