We would like to introduce a case study of "surface roughness measurement," which has a significant impact on light, conducted by our company. Depending on the surface condition, such as the surface of parts inside a camera, after painting or machining, there may be difficulties in assembling fitting parts, incorrect assembly heights, or the occurrence of ghost flares. It is possible to measure fine variations in height and overall distortion of thin products in an easily understandable manner using color mapping in 3DCG. We also accept inquiries regarding the feasibility of measurements and consultations on specified measurement locations. 【Case Overview】 ■ Measurement Items - Ra, Rz - 3DCG of measurement range - Fine height variations on the surface ■ Measurement Device: Optical Surface Profilometer "Zygo NewView7300" *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of "reflectance measurement" conducted by our company. High reflectance on the surface of components often leads to harmful ghosts, and examining the reflectance of the measurement surface can be helpful for improving coatings and surface treatments. It is possible to measure transparent items like lenses with anti-reflective coatings, as well as black components with irregularities. We also welcome inquiries regarding specified samples and measurement locations. 【Case Overview】 ■Measurement Item: Reflectance between wavelengths of 380 to 780 nm ■Measuring Instrument: Microspectrophotometer "Olympus USPM-RU" *For more details, please refer to the PDF document or feel free to contact us.

Our company offers a birefringence measurement service as one of the applications for evaluating optical performance. Birefringence is a phenomenon where light travels at different speeds in different directions, primarily caused by the molecular orientation of materials and internal stresses that occur during injection molding. This phenomenon can lead to a decrease in the optical performance of lenses, resulting in image distortion and misalignment of focus. Tokyo Shinbi Optical Electronics strongly supports your manufacturing with a wealth of experience and know-how cultivated in micro-lens development. 【Case Overview】 ■ Measurement Item: Birefringence ■ Measurement Device: Birefringence distribution measurement system for small lenses "Photonic-lattice manufactured WPA-100" *For more details, please refer to the PDF document or feel free to contact us.
