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.
| Industry | Application |
|---|---|
| Machine Vision | Vision light source base plate, LED light bar mounting liner |
| Optical Assembly | Optical component positioning pad, optical path spacer block |
| Vacuum Coating | Coating fixture carrier, small lens support pallet |
| Laboratory | High-temperature sample carrier plate, corrosion test platform base |
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
