What Is Silicate Optical Glass?
Silicate optical glass is a type of amorphous material composed primarily of silicon dioxide (SiO₂) and various metal oxides. Known for its excellent optical clarity, high refractive index, and low thermal expansion, it is widely used in precision optical components such as lenses, prisms, windows, and beam splitters.
Compared with borosilicate or phosphate glass, silicate optical glass offers greater versatility in optical design and better compatibility with high-precision coatings.
Key Properties of Silicate Optical Glass
- High Refractive Index: Ranges from 1.5 to 1.9, enabling compact optical designs
- Low Dispersion: Achieves minimal chromatic aberration in lens assemblies
- Excellent Transparency: High transmission in visible and near-infrared ranges
- Good Thermal and Mechanical Stability
- Ideal for Coating: AR, mirror, beam splitter, and filter coatings adhere effectively
