Product Description
Our quartz capillary tubes are manufactured from 99.99%–99.999% high-purity fused silica, delivering exceptional thermal stability, high optical transmittance, and broad chemical resistance.
This range covers 1mm to 6mm outer diameter with a 100mm standard length. These precision hollow tubes are widely used in fiber optic communications, optical sensing, laser systems, laboratory analysis, and semiconductor manufacturing.
Key Features
OD options: 1 / 1.5 / 2 / 2.5 / 3 / 4 / 5 / 6mm — ID and overall length are fully customizable
Temperature range: -198°C to 1200°C, with excellent thermal shock resistance
Optical performance: High transmittance and low dielectric loss for photonics applications
