Core features:

High transmittance: The transmittance exceeds 90% in the ultraviolet (UV), visible light, and near-infrared (NIR) bands (180-3500nm), meeting the strict requirements of optical systems for light loss.

High temperature resistance and chemical stability: with a melting point of up to 1713 ℃, it can work stably in an environment of 1100 ℃ for a long time; Acid and alkali resistant, suitable for extreme chemical environments.

Low thermal expansion coefficient: The thermal expansion coefficient is only 5.5 × 10 ⁻⁷/℃, ensuring dimensional stability at high temperatures and reducing the risk of deformation or cracking caused by thermal stress.

Uniformity control: Through precision drawing technology, the diameter tolerance can be controlled within ± 0.02mm, and the roundness error is ≤ 0.01mm, meeting the requirements of high-precision assembly.

The product specifications cover diameters from 0.5mm to 200mm and lengths from 10mm to 3000mm, supporting customized sizes and surface treatments (such as polishing, coating, sanding, etc.), suitable for diverse application scenarios.
