Half Round Quartz Rods

Name: Half Round Quartz Rods
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

The half-round quartz rod is basic structural components of optical communication devices. It has high precision, high hardness, and excellent environmental resistance.Its coefficient of thermal expansion are the same as that of optical fiber.It is used in optical devices such as optical couplers, ribbon fiber welding protectors, high-power lasers, etc.The main manufacturing method is to prefabricate the quartz rod, clamp it above the high-temperature graphite furnace after cleaning, and send it into the heart of the high-temperature graphite furnace protected by inert gas to perform a series of program operations such as continuous pulling, drawing, and cutting, directly and quickly produce quartz rod with transparent surfaces in large quantities, with high dimensional accuracy and suitable for mass production. It can significantly reduce component costs and improve component quality.

Features of Half Round Quartz Rods

Material: High-purity fused quartz, silicon dioxide (SiO2) content >99.9%, softening point >1650°C, high strength, high wear resistance, high light transmittance.
Usage Properties: The half round quartz rod is melted and drawn at high temperature. The surface is transparent, which eliminates surface micro-cracks and local surface hidden cracks in the optical fiber positioning holes. The half round quartz rod has high strength and is not easy to crack and break when dispensing glue to fix the optical fiber. The dispensing is qualified. The rate is high.
Environmental Properties: The hydroelectric composite wire drawing production process does not use any chemical solvents, and the material and production process do not contain or involve controlled substances required by the EU RoHS directive and Reach regulations.
Quality Stability: Through the closed-loop control of the CNC host, feeding mechanism, traction mechanism, and laser rangefinder, half round quartz rod with the required diameter and inner diameter can be accurately drawn. The precision consistency is very high and the production stability is excellent.
Customized Structure: Using a high-precision grinder to finely grind the half round quartz rod plane, various structures can be customized to meet the requirements for connecting and fixing optical devices.
