Description

Product Overview

The High Purity Fused Silica Quartz Substrate Strip is a precision-ground quartz glass strip (185mm x 5mm x 4.2mm) engineered for machine vision, optical assembly, vacuum coating, and laboratory applications. Manufactured from premium fused silica (SiO2 > 99.99%) with tight dimensional tolerance control, this strip delivers superior thermal stability, chemical inertness, and optical clarity.

Key Features

  • High Purity Fused Silica: SiO2 > 99.99% with ultra-low impurity content, ensuring contamination-free operation in sensitive applications
  • 1100°C Temperature Resistance: Maintains structural integrity at extreme temperatures without softening or deformation
  • HF & Strong Corrosive Resistance: Outstanding chemical durability against hydrofluoric acid, strong acids, and alkalis
  • Precision Ground Surface: Fine polished with tight dimensional tolerance for precise assembly and positioning
  • Low Thermal Expansion: CTE of 5.5 x 10^-7 /°C prevents cracking, warping, and edge chipping under thermal cycling
  • Excellent Light Transmittance: High optical clarity suitable for vision system and optical path applications

Applications

IndustryApplication
Machine VisionVision light source base plate, LED light bar mounting liner
Optical AssemblyOptical component positioning pad, optical path spacer block
Vacuum CoatingCoating fixture carrier, small lens support pallet
LaboratoryHigh-temperature sample carrier plate, corrosion test platform base

Competitive Advantages

vs. Borosilicate Glass: Superior HF acid resistance; no softening or deformation at high temperatures exceeding 500°C; significantly lower thermal expansion prevents cracking

vs. Plastic Components: Excellent organic solvent resistance; long-term dimensional stability without yellowing or warping; suitable for high-temperature and corrosive environments
