Neonode: zForce


Recently, Neonode's optical touch solution - zForce hits ASUS portable device. The most possible is tablet such 5~13" display size. That's very interesting. Compared with iPad that use 9.7" (in diagonal) capacitive touch panel, ASUS pad-like product could use bigger size. Bigger size, higher cost for capacitive touch. Maybe it is the cost issue make zForce attractive.

Optical mount

Optical mount is a mechanical part of optical systems, determining the alignment, robust, and precision. Any variation would affect optical performance in geometric and these factors are vibration, temperature drift, acoustic fluctuation, shock, chemical corrosion...etc.

Mirror is particularly sensitive to any fluctuation because any geometric variation would amplify the change of optical path. For example, angle tilt of mirror causes reflection angle double.
