東京晨美光学電子 List of Products and Services

We would like to introduce a case study on "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, issues like difficulty in assembling fitting parts, incorrect assembly heights, and ghost flares may occur. It is possible to conduct clear measurements of fine height differences and overall distortion of thin products using color maps in 3DCG. We also welcome inquiries regarding the feasibility of measurements and consultations on specified measurement locations. 【Case Overview】 ■Measurement Items ・Ra, Rz ・3DCG of measurement range ・Fine height differences on the surface ■Measuring Instrument: 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 the occurrence of harmful ghosts, and examining the reflectance of the measurement surface can be helpful for improving coatings and surface treatments. Transparent items like lenses with anti-reflective coatings, as well as black components with uneven surfaces, are also possible. We 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 the focus. Tokyo Shinbi Optical Electronics strongly supports your manufacturing efforts with the various experiences and know-how gained from micro-lens development. 【Case Overview】 ■ Measurement Item: Birefringence ■ Measurement Device: Birefringence distribution measurement system for small lenses, "Photonic-lattice WPA-100" *For more details, please refer to the PDF document or feel free to contact us.

Our company uses the ultra-high precision three-dimensional measuring machine UA3P to measure lens aspheres and correct them with an aspheric processing machine, thereby enhancing the optical performance of the lens unit. When using optical lenses, it is necessary to evaluate whether the lens surfaces are "made according to the design specifications" and "how much they differ from the design specifications." We also accept consultations regarding the measurement of lens product surface shapes and the processing of aspheric components manufactured by our customers. [Case Summary] ■Measurement Items ・Lens Surface Shape ・Aspheric Coefficient ■Measuring Device: Ultra-high Precision Three-Dimensional Measuring Machine "Panasonic UA3P-300" *For more details, please refer to the PDF document or feel free to contact us.
