The Square Glass Cover Shield is a compact protective housing with an outer dimension of 26.7 x 25.4 x 23mm, integrally thermoformed from optional 3.3 borosilicate or fused silica. The seamless whole structure provides a clean, joint-free enclosure that protects miniature light sources, sensors and optical components from dust, contamination and mechanical impact. The even, transparent wall is free of bubbles, stones and striae, delivering uniform light transmittance for optical applications. With a low thermal expansion coefficient and crack-resistant construction, the shield withstands sharp temperature changes, while its acid and alkali resistance keeps it reliable in demanding laboratory environments.

The Square Glass Cover Shield is designed for compact optical and laboratory systems that require reliable component protection. It is widely used as a protective cover for miniature light sources, shielding lamps and emitters from dust and damage while allowing light to pass. In sensing systems, the shield serves as a light-transmitting protection cover for sensors, guarding the sensing element without blocking its optical response. The component also works as a dust cover for spectral components, keeping optical surfaces clean for stable readings. In laboratory settings, it functions as an isolation cover for micro lab parts, preventing cross-contamination during experiments. Additionally, the shield is adopted as a sealed protective cover for precision optical paths, maintaining a stable environment for sensitive optical assemblies.
