The Square Fused Silica Spacer is a miniature precision shim with a dimension of 3 x 3 x 1.5mm, manufactured from high-purity fused silica with a grade -1 negative precision tolerance. The finely ground, polishable surface provides high plane parallelism and is free of chipping, scratches and bubbles, ensuring stable seating and accurate spacing in precision assemblies. With high UV transmittance, an ultra-low thermal expansion coefficient and excellent resistance to high temperature and acid and alkali, the spacer maintains its geometry under thermal cycling with negligible deformation. Its excellent insulation and consistent batch quality make it a reliable component for optical and testing equipment.

The Square Fused Silica Spacer is designed for precision optical and testing equipment that requires accurate spacing and stable alignment. It is widely used as a spacer shim in optical assemblies, maintaining precise gaps between lenses, mirrors and detectors. In testing equipment, the spacer supports components at controlled heights, ensuring repeatable measurement geometry. The component also functions as a positioning pad in precision instruments, providing a stable, inert platform that does not scratch optical elements. Additionally, the spacer is adopted in semiconductor and laboratory fixtures, where its negative tolerance and thermal stability keep assembly clearances consistent across temperature changes.
