Design Birefringence & Stress Strain Measurement We have improved conventional birefringence measurement from point measurement to 2-D surface measurement. High-speed, high-precision birefringence measurement contributes to quality evaluation and functional improvement of optical materials. MORE Next-generation Optical Communications Polarization control is becoming increasingly important in next-generation optical communications. In addition to application examples of our proprietary photonic crystals, we also introduce upcoming functions in the future. MORE
