Optical Glass Materials

- OptoNest’s optical glass materials have a high refractive index and low transition temperature characteristics, enabling GMP (glass molding press) lens molding and replacing existing high-cost single-crystal glass materials.
OptoNest has secured optical glass material manufacturing technology suitable for the manufacture of high-precision optical products, such as customized glass development, aspheric lenses suitable for press molding, high-refractive index optical glass, and low-melting-point glass.
Features
- Low transition temperature characteristics enabling GMP lens molding
- Excellent workability and hardness
- Optical glass material for aspheric lenses with high refractive index
- High homogeneity and low birefringence
- Excellent visible light and infrared transmittance
Applications
- Aspheric optical lenses for optical communication
- Optical lenses for vehicle cameras
- Optical lenses for smartphone and drone
- Optical lenses for visual light/mid infrared cameras
- Camera optical lenses for high temperature measurement
