Core Features
  • Smooth inner hole without burrs: The precision-drilled bore is clean and burr-free, allowing smooth insertion and accurate alignment of shafts and fibers.
  • Bubble and inclusion free smooth surface: The defect-free surface provides stable optical and mechanical contact in precision assemblies.
  • High dimensional precision: OD, thickness and hole diameter are controlled within tight limits for dependable fit and interchangeability.
  • Excellent chemical stability: The material resists common reagents and cleaning agents, keeping the component clean and reliable in service.
  • High coaxiality of through hole: The hole is concentric with the outer diameter, ensuring uniform alignment in optical path systems.
Application

The Perforated Precision Glass Middle Quartz Plate is designed for miniature optical and laboratory systems that require precise spacing and alignment. It is widely used in miniature optical assemblies as a positioning element that guides light paths through its central hole. In testing instruments, the quartz plate serves as a spacer gasket, maintaining accurate separation between components with uniform clearance. The component also functions as an optical path positioning part, helping align beams and elements in compact optical systems. Additionally, the quartz plate is adopted as a micro experimental carrier, providing a stable and chemically inert platform for holding small samples during analysis and measurement.

Advantages
  • High coaxiality of through hole: Concentric hole and outer diameter ensure accurate optical and mechanical alignment.
  • Uniform assembly clearance: Consistent dimensions deliver even gaps around assembled parts for stable performance.
  • Wear-resistant and anti-deformation: The durable glass structure maintains its shape and precision under repeated use.
  • Fit for miniature precision optical equipment: Compact size and tight tolerances make the quartz plate ideal for small optical instruments.
