Relying on advanced synthesis and purification processes and precision machining technology, our products have extremely high purity, wide spectral transmission, and excellent thermal stability. They are widely used in cutting-edge fields such as optical communication, laser transmission, medical equipment, and industrial sensing, and are the core cornerstone for ensuring the stable operation of high-end optoelectronic systems.

From the perspective of users, we are well aware that even small defects in materials can lead to a decrease in system performance in complex optical applications. Our fiber optic quartz light guide rod is dedicated to solving your core needs: firstly, by controlling extremely low metal impurities and hydroxyl content, it significantly reduces optical signal transmission loss and meets long-distance or high-precision transmission requirements; Secondly, with its extremely low coefficient of thermal expansion and excellent thermal shock resistance, it effectively suppresses the thermal lens effect in high-energy laser environments, ensuring stable beam quality; Finally, we provide comprehensive size customization services from core diameter, outer diameter to length, perfectly adapting to the assembly needs of various non-standard optical systems and helping you overcome technical challenges in research and production.

Advantages and Application Value

As a leading manufacturer of high-purity fiber quartz light guides in the industry, Luverre Quartz provides solid material support for your projects with strict standards and customization capabilities

Ultimate purity and low loss transmission: Using high-purity chemical synthesis processes (such as CVD/OVD), the total amount of metal impurities such as iron and aluminum is controlled at ppb level, and the hydroxyl content is as low as ≤ 1ppm. This fundamentally eliminates light absorption and fluorescence background, allowing the product to maintain ultra-high transmittance of ≥ 99% in a wide spectral range of 200nm to 2500nm, greatly improving the efficiency of light energy transmission.

Excellent thermodynamic and mechanical stability: The softening point is as high as 1683 ℃, and the coefficient of thermal expansion is only 5.5 × 10 ⁻⁷/℃. Even under kilowatt level continuous laser shock or severe temperature fluctuations, it can maintain minimal deformation, avoid focal drift, and ensure the reliability of the optical system under extreme working conditions.

Full specification flexible customization service: We break through the limitations of standard parts and provide highly flexible customization solutions. Whether you need a capillary light guide rod with a diameter of 1mm or a large-sized special light rod with an outer diameter exceeding 60mm; Whether it is a short distance connection of 0.5 meters, a customized length of several meters, or even secondary processing such as end face flame polishing and irregular milling grooves, they can be delivered as needed, and the geometric tolerance is strictly controlled within ± 0.05mm.

Defect free optical uniformity: After strict annealing and precision testing, each light guide rod is ensured to have no bubbles or stripes inside, and the birefringence difference is extremely low. This provides an ideal medium for applications such as high-precision spectral measurement and deep ultraviolet lithography that are extremely sensitive to wavefront distortion.

Cracking Application Difficulties and Customer Success Stories

In practical applications, different industries face their own unique technological challenges. We have successfully helped numerous customers solve problems through precise material formulas and process optimization

Case 1: Overcoming the "thermal lens" challenge of high-power laser cutting equipment

A well-known European laser equipment manufacturer encountered a bottleneck when upgrading a 4kW fiber laser cutting head: the original ordinary quartz light guide rod, under long-term full load operation, suffered from severe thermal lens effect due to heat absorption, causing focal drift and rough cutting edges. After receiving the request, we tailored an ultra-low hydroxyl, high-purity synthetic quartz light guide rod for it. By optimizing the absorption coefficient of the material at a wavelength of 1064nm and improving the absolute uniformity of geometric dimensions, the perfect distribution of laser energy during transmission within the rod is ensured. After replacing our light guide rod, the device ran continuously for 8 hours with zero drift in the focal position, and the smoothness of the cutting section was greatly improved by 30%. The customer immediately listed us as the designated raw material supplier for this series of lasers.

Case 2: Breaking through the signal attenuation barrier of deep ultraviolet Raman spectrometer

A top research institution is facing a severe challenge in building a deep ultraviolet Raman spectroscopy system: it urgently needs a light guiding fiber with high transmittance and no fluorescence background below 240nm, but conventional products on the market will produce strong stray light interference. To address this challenge, we have adopted a special plasma assisted deposition process to provide customized quartz light guides with high hydroxyl content. The high hydroxyl group effectively saturates the oxygen vacancy defects in the quartz structure, significantly improving the deep ultraviolet transmittance and thoroughly suppressing the fluorescence background.
