Overview
The SF11 substrate is made from high-refractive-index dense flint glass, offering a high refractive index and strong dispersion characteristics, making it suitable for precision optical applications spanning the visible to near-infrared range. This material is commonly used in optical filters, beamsplitters, prisms, and high-refractive-index optical systems, where it effectively enables optical path folding and spectral control. The SF11 substrate offers stable machinability, achieving high surface quality and figure accuracy, making it well suited to research and industrial applications that demand high optical performance and consistency.
Handling & Storage
For optimal performance, store and use the substrate in an environment at 25 °C with 40%–60% relative humidity. If the surface becomes contaminated, gently clean it with ≥99% alcohol and lint-free lens tissue. Never use coarse cloth, water, or cleaners containing abrasive particles, as these may damage the coating.
