Overview
Otsuka Optical Glass is a specialized glass formulation produced by Otsuka Chemical, designed for precision optical applications. It is engineered to deliver exceptional clarity, minimal light scattering, and consistent performance under varying environmental conditions. The material is favored in industries requiring high-precision optics, such as photography, scientific instrumentation, and medical imaging. Its composition is tailored to meet specific optical properties, including refractive index and dispersion control, making it adaptable to diverse technical requirements.
Physical and Chemical Properties
Otsuka Optical Glass exhibits a high refractive index (typically 1.5-1.9) and low chromatic aberration, critical for minimizing color distortion in lenses. Its thermal expansion coefficient is carefully controlled to ensure stability under temperature fluctuations. Chemically, the glass is inert and resistant to most acids, alkalis, and solvents, though prolonged exposure to harsh chemicals may cause surface etching. Its hardness (Mohs scale 5-7) and scratch resistance make it suitable for applications requiring durability.
Main Applications
The primary use of Otsuka Optical Glass is in high-end lenses for cameras, microscopes, and telescopes, where its light transmission and minimal distortion are paramount. It is also employed in laser systems, fiber optics, and semiconductor lithography equipment. In the medical field, the glass is used in endoscopes and diagnostic devices due to its biocompatibility and sterilization resistance. Emerging applications include augmented reality (AR) displays and automotive LiDAR sensors.
Safety and Storage
While non-toxic, Otsuka Optical Glass requires careful handling to prevent chipping or cracking. Edges should be polished to reduce injury risk during installation or maintenance. Storage recommendations include keeping the glass in padded containers, away from humidity and direct sunlight. For long-term preservation, anti-fog coatings or desiccant packets may be used to prevent moisture buildup.
B2B Procurement Guide
When sourcing Otsuka Optical Glass, buyers should provide detailed specifications, including geometric tolerances, surface quality (e.g., scratch-dig standards), and coating requirements. Custom formulations (e.g., UV-blocking or IR-transmitting variants) may require extended lead times. Suppliers often offer technical support for prototyping and testing. Bulk purchases (e.g., 100+ kg) may reduce unit costs by 10-20%. Verify certifications like ISO 9001 for quality assurance.
