Felix Glass is a professional custom quartz rod manufacturer and OEM optical quartz fabrication supplier, supplying semiconductor-grade precision optical quartz components for light guide manufacturers, laboratory thermal equipment, semiconductor processing lines and optical instrument factories worldwide.
Our quartz glass rods are extruded from 99.99% high-purity fused silica with JGS1 deep UV grade, JGS2 UV-Vis grade and JGS3 infrared grade. Solid quartz bars feature ultra-low CTE, excellent deep UV transmittance, outstanding thermal shock resistance and stable chemical inertness. Widely used as light guide rods, high-temperature support shafts, stirring rods and optical transmission media in industrial and laboratory environments.
We provide custom diameter, cutting length, end polishing, chamfering and shaping processing, fully comply with ISO 9001 quality standards, supporting lab prototype sampling and large OEM mass production.

Frequently Asked Questions
-
1. Q: What is the MOQ for custom quartz glass rods?A: Ultra-low MOQ supported, short small-diameter sample rods available for optical lab testing.2. Q: Can you produce quartz rods according to customer dimension drawings?A: Our optical engineering team accepts custom diameter & length requirements, free drawing review and 24-hour quotation.3. Q: Which quartz grade is suitable for UV light guide rods?A: JGS1 low-OH deep UV grade ensures high and stable deep ultraviolet light transmittance.4. Q: What maximum temperature can solid quartz rods bear?A: Stable continuous operation up to 1100°C, no cracking under rapid cold and hot alternation.5. Q: Can both ends of quartz rods be mirror polished?A: Yes, double-end high-precision polishing for light coupling and light guide transmission.6. Q: What is the minimum customizable diameter of quartz rod?A: Minimum solid rod diameter reaches 1mm for micro optical instruments.7. Q: Is quartz rod resistant to acid chemical corrosion?A: Inert to almost all acids except hydrofluoric acid, widely used for chemical lab stirring.8. Q: Can quartz rods be chamfered or ground into special shapes?A: Edge chamfering, step grinding and special profiling processing are all available.9. Q: What’s the difference between quartz rod and quartz tube in light transmission?A: Solid quartz rod achieves higher light coupling efficiency for light guide systems; tubes are mainly for gas/liquid flow channels.10. Q: Do you provide fixed-length cutting service for raw quartz rods?A: All solid bars can be precisely cut to any specified length as required.
