1. Manufacturing Process

Careful wafer preparation is the foundation of producing a high-quality Silicon Window (Si) with a 50.8 mm diameter and 3.0 mm thickness. During the initial phase, silicon substrates are precisely cut and rigorously inspected for surface defects. Once the starting material meets stringent requirements, specialised grinding and polishing steps ensure the window achieves a uniform surface finish that supports optimal clarity and strength. This precise dimensional control is vital to maintaining the specified 50.8 mm diameter, as well as the consistent 3.0 mm thickness throughout the entire batch.

Efficiency in deposition techniques plays a significant role in creating the durable anti-reflective (AR) coating on these silicon windows. Vacuum coating processes such as electron-beam evaporation or ion-assisted deposition are commonly used to apply thin, uniform layers that reduce reflection losses and enhance transmittance. After the coating is applied, the component undergoes comprehensive testing to confirm adherence to design tolerances and performance benchmarks. This multi-stage manufacturing sequence guarantees that each Silicon Window (Si) Dia. 50.8 mm x Thk. 3.0 mm, AR Coating meets the demands of precision-driven applications.
