Application

Lens Defect Inspection
A non-destructive inspection with laser is developed. The defects, e.g. flow-mark,
in a transparent material ( such as light guide, optical film and lens ... etc.) could be defined quantitatively by Fourier transform image analysis. The method is intended to replace the human eye , and therefor to effectively classify the defects and result in a better manufacture process and quality control.
Gas Sensing


CRDS
Cavity ring-down spectroscopy (CRDS) is a highly sensitive optical
spectroscopic technique, which has been widely used to study gaseous samples which absorb light at specific wavelengths, and in turn to determine mole fractions down to the parts per billion level. A system to measure the WVTR is developed to meet the criteria of <1 x 10-6 g/m2/day , which classify the barrier material in OLED industry to achieve a device lifetime of >10,000 hours.

PAS
Photo-acoustic spectroscopy (PAS) is now a commonly used method for analysis of gas samples. Laser photo-acoustic detection offers some unique features, such as low sample volume, high sensitivity and wide linear dynamic range. Signal is generated only from the absorption thus being a so called zero-background technique. Major advantage is the fact that sensitivity is basically not dependent on the optical path length. This allows high sensitivity from short absorption path length and highly linear concentration response over a wide dynamic range from very low sample volumes.










Laser Processes
Laser technology is suitable for processing a broad range of different materials. The material processes include the separation, joining and surface treatments. Consulting, feasibility studies and process evaluation are provided for customers to shorten the development cycle times.
