10-3500mm transparent high-temperature resistant optical rod quartz rod is a high-purity quartz glass product with excellent transparency, high temperature resistance, and chemical stability. This product is made of high-purity fused silica, which can work stably in extreme temperature (up to 1200 ℃) and harsh environment for a long time, and is widely used in optics, semiconductor, medical, scientific research and industrial fields.

Frequently Asked Questions (FAQ)

What is the transmittance range of this quartz rod?

Quartz rods have good transmission performance in both ultraviolet and near-infrared continuous spectra, covering wavelengths from 0.18 μ m to 2.2 μ m. The transmittance in the 253.7nm ultraviolet band can reach over 87%, and the transmittance in visible light is ≥ 93%. They are suitable for optical systems such as spectral analysis and laser transmission.

What is the specific size range that can be customized?

The diameter can be customized from 10mm to 3500mm, and the length can be produced according to demand, supporting processing according to drawings. Whether it is micro optical sensing components or large industrial light guiding components, precise customization can be achieved.

What is the temperature resistance performance of the product?

The softening point of quartz glass is 1730 ℃, and the annealing point is about 1210 ℃. It can be used continuously for a long time at a high temperature of 1200 ℃. The coefficient of thermal expansion is only about 0.55 × 10 ⁻⁶/K, which can withstand severe temperature fluctuations.

How about surface treatment and end face accuracy?

The circumference of the rod is transparent, and the end face can be polished to optical grade to achieve a surface quality level of 60/40, ensuring optical transmission efficiency. End face blackening, sanding, or coating with anti reflective film can also be carried out according to the needs.
