For R&D and production personnel in the fields of precision optics, semiconductors, and fiber optic communication, finding high-quality optical perforated quartz discs often faces many challenges: ensuring the roundness and perpendicularity of micropores, as well as meeting extremely high surface smoothness and temperature resistance.

What is an optical perforated quartz disc? What core problems can it solve?

In the field of optics and electronic packaging, optical perforated quartz discs (referred to as through-hole quartz discs) are mainly used to achieve precise transmission, electrical interconnection, or precise positioning of optical signals. Here are the core problems it can solve for you:

Solving the problem of optical path alignment: providing high-precision through holes to ensure precise micrometer level docking of optical fibers or components during assembly, reducing signal loss.

Meeting the requirements of high temperature resistance and insulation: Quartz material has an extremely low coefficient of thermal expansion and excellent electrical insulation, solving the problem of structural deformation or short circuit under extreme temperature changes.

Dealing with special shapes and sizes: Breaking through the limitations of standard parts, whether it is non-standard diameter, micro pore size (as small as 0.1mm) or irregular cutting, customized services can solve your R&D bottleneck.

Product advantages and application areas

Why choose optical perforated quartz discs?

Compared to ordinary glass or metal substrates, quartz perforated discs have irreplaceable advantages:

1. Extremely low coefficient of thermal expansion (CTE): Maintaining geometric stability in high-temperature processes or drastic temperature fluctuations to ensure long-term reliability of optical systems.

2. Excellent optical transmittance: Wide spectral transmittance from ultraviolet to infrared, suitable for various optical communication and laser application scenarios.

3. High precision machining: The aperture tolerance can be controlled within ± 0.01mm, the hole wall is smooth without any broken edges, and the edges are free of burrs.

4. Chemical inertness: resistant to strong acid and alkali corrosion, suitable for harsh chemical treatment environments.

Customer Application Cases

In order to provide you with a more intuitive understanding of our production capacity, the following are two anonymous real-life application cases:

Case 1: Fiber Array Substrate Requirements for High Speed Optical Module Manufacturers

Customer requirement: A high-speed optical module manufacturer needs to develop the next generation of 400G optical modules. They require a quartz disc with a thickness of 0.5mm and a diameter of 50mm. Four sets of high-precision V-shaped grooves and a set of vertical through-hole arrays need to be processed on the disc to accurately fix the optical fiber and achieve vertical coupling. The aperture tolerance must be strictly controlled within ± 0.002mm, and the hole wall must reach the mirror polishing level to prevent damage during fiber insertion.

Solution: We use high-purity fused silica material, combined with CNC microporous processing and laser assisted polishing process. Firstly, the through-hole position is located through precision machining, and then the hole wall is subjected to stress relief treatment and surface optimization using special polishing solution to ensure a smooth and crack free inner wall of the hole. At the same time, a high-precision forming grinding wheel is used to machine a V-shaped groove array with an angle tolerance of less than 0.1 ° on the surface of the disc.

Final effect: The finished product passed the customer's insertion loss and return loss tests, reducing fiber insertion loss by 15% and increasing coupling efficiency by 20%. It successfully helped the customer complete sample verification within 45 days and smoothly transition to mass production.

Case 2: Irregular through-hole substrates for microfluidic chips in research institutions

Customer demand: A top university's biotechnology laboratory is developing a new type of single-cell capture chip, which requires a 20mm x 20mm quartz square with a thickness of 1mm. It is required to process a shaped cross hole structure with a diameter of 0.1mm for constructing three-dimensional fluid channels. Due to the advanced exploration stage of the experiment, the initial demand is only 5 pieces, but it requires extremely high shape accuracy, and the material must have no fluorescence characteristics to avoid background interference.

Solution: We use customized micro electroplating grinding heads for micro milling processing, combined with an online CCD positioning system to ensure that the intersection of the cross holes is located at the center of the substrate. At the same time, we thoroughly cleaned and annealed the substrate to remove surface fluorescent residues, and provided a fluorescence detection report for the quartz material.

Final effect: Five samples were validated through laboratory high-power microscopy and fluorescence analysis at once. Its high-precision irregular through-hole structure perfectly fits the microfluidic system in the laboratory, helping researchers successfully achieve precise capture and observation of single cells.
