Customized Irregular-shape Quartz Optical Windows JGS1/JGS2/BF33 Grade
Customized irregular quartz optical windows are engineered from high-purity silicon dioxide (SiO₂), designed to address complex optical system requirements by breaking traditional geometric constraints (e.g., circular/square formats). These windows support non-standard shapes such as ellipses, polygons, and free-form curves. Core advantages include high-temperature resistance (1,100°C continuous use), low thermal expansion coefficient (5.5×10⁻⁷/°C), broad-spectrum transparency (185–3,500 nm), and chemical inertness, making them ideal for extreme environments in precision optical devices. ZMSH specializes in full-cycle customized production, offering end-to-end services from design to delivery, serving high-end sectors such as semiconductors, laser technology, and aerospace.
