Optical Characterization

Optical Characterization Optical characterization is the process of measuring how materials and thin films interact with light. Common optical measurements include reflectance, transmission, absorbance, refractive index, extinction coefficient, and film thickness,...

Optical Filter

Optical Filter Optical filters selectively transmit or block specific wavelengths of light and are widely used in spectroscopy, fluorescence microscopy, machine vision, laser systems, telecommunications, and scientific instrumentation. Their optical performance...

Wafer Metrology

Wafer Metrology Wafer metrology refers to the measurement and characterization of thin films, surface properties, and process parameters throughout semiconductor manufacturing. Accurate wafer metrology helps improve process control, increase manufacturing yield, and...
