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.

Toshiba 3CCD

Toshiba's IK-HD1 is a very small 3CCD camera, which dimension size is 32.6x38.6x41mm and 65g in weight. 3CCD uses three CCD image sensor chips to record R,G,B separately, unlike common demosaic type camera that each pixel contains three color filters.

How Kinect works with PrimeSense


Microsoft applys 3D motion sensing technology into XBox - Kinect, letting users interact with gaming freely without controller in hand. Camera and gesture recognition make the function of motion sensing. PrimeSense delivers the chip and structure to the 3D sensing technology, helping Microsoft to achieve controller-free entertainment device.

Edmund open Taiwan office

Edmund optics, supplier of optical components, open an office in Taichung, Taiwan.

Johnson Chang  is the leader of sales team in new office. Edmund expect rapid growth in demand for optical components, especially vision systems and lens.

It took long time that Edmund decided to open office in Taiwan.
Before, there were many distributors to sell Edmund products. But most customers buy small and low cost components,and even some like to shop online for cheaper price.
If Edmund build a service team in Taiwan, this would make their advanced products attractive.

EUV lithography-2

Throughput is a big issue of EUV.
Why?

1.Reflective optics has finite reflectivity about 70% at 16.5nm(EUV wavelength).
2.There are more than 11 reflection surfaces from light source to waver.

So very small light power pump into waver.
One solution is to enhance the reflection of multi-layer coating, and another is to increase the power of light source.
