1. Manufacturing Process

Careful fabrication of the Silicon Window (Si) Dia. 50.8 mm x Thk. 1.0 mm begins with precision cutting from high-purity silicon ingots. The raw silicon is sliced into discs using diamond-tipped saws, ensuring minimal mechanical stress to preserve crystal integrity. Following this step, the window undergoes multiple stages of lapping and polishing to achieve an ultra-smooth surface, which is vital for optimising clarity and minimising scattering effects. Specialised equipment is used to maintain strict control over surface flatness and parallelism, resulting in consistent optical performance across the entire disc.

Intensive quality checks are performed throughout the manufacturing pipeline to verify surface roughness and thickness uniformity. After the polishing stage, an anti-reflective (AR) coating is meticulously deposited on both sides of the silicon window. This thin film is critical for minimising reflections across a specific wavelength range, thereby increasing overall transmission. The final product, with its 50.8 mm diameter and 1.0 mm thickness, offers high durability and stable performance even when subjected to challenging environmental conditions.
