Solid transparent quartz light guide column

Solid transparent quartz light guide column is an optical conductive component that utilizes the excellent optical transmission properties of high-purity quartz glass to efficiently convert point light sources into line or surface light sources. It has extremely low light absorption rate, excellent high temperature resistance, and UV radiation resistance, and can maintain long-term stable transmission in harsh semiconductor, lithography, special lighting, and medical equipment environments. As the core bridge connecting the light source and the working surface, this light guide column can effectively solve the problems of thermal damage and light attenuation in optical path integration, and is an indispensable key component for high-end optoelectronic applications.

Frequently Asked Questions (FAQ)

Q1: What is the maximum temperature that a solid transparent quartz light guide column can withstand?

A: Made of high-purity quartz glass, it has a softening point of over 1200 ℃, a long-term safe use temperature of up to 1100 ℃, and a short-term resistance to high temperatures of 1300 ℃, making it very suitable for optical transmission in high-temperature environments.

Q2: What specifications and shapes can you customize for your light guide columns?

A: We provide comprehensive customized services. Whether it is diameter, length, tolerance requirements, or irregular structures such as cylinders, square columns, cones, threaded or special chamfers, precise machining can be carried out according to customer drawings or specific application needs.

Q3: How to ensure the optical transmission efficiency of the light guide column?

A: We use optical grade quartz blanks and employ precise cold processing techniques (such as precision grinding and polishing) to ensure that the end surface smoothness reaches the λ/10 level. The side surface is polished or frosted as needed to minimize internal scattering and end surface reflection losses.

Q4: Do you provide cleaning and packaging that meets semiconductor industry standards?

A: Yes, it is. We have a hundred level ultra clean room cleaning capability and can perform dust-free cleaning according to customer requirements. We use anti-static and vacuum nitrogen packaging to meet SEMI standards and are directly applicable to clean room environments.

Addressing your core needs

From your perspective, the solid transparent quartz light guide column truly solves the following core problems for you:

Solving the problems of light attenuation and thermal offset: Under strong light or high temperature conditions, ordinary glass will yellow and deform, causing light attenuation. Quartz light guide columns ensure stable output of light flux.

Solving the problem of uniform lighting under limited space: Transforming the difficult to directly arrange heat dissipation point light sources into uniform line/surface light sources simplifies the optical design structure of the equipment.

Solving the problem of consumable lifespan in harsh environments: With extremely strong corrosion resistance and UV resistance, it significantly reduces the maintenance frequency and replacement cost of equipment in strong acid-base or UV environments.

Core application areas:

Semiconductors and Microelectronics: lithography machine uniform illumination module, wafer detection light source conduction.

Special light sources and medical: UV curing equipment, UV sterilization lamp tube optical path coupling, laser medical equipment conduction.

Industry and research: observation window for high-temperature infrared heating furnace, spectrometer optical path system, high-end experimental equipment.

The value of product advantages to users:

Extremely high transmittance (value): The transmittance exceeds 93% in the ultraviolet (190nm-400nm) to visible and near-infrared bands, ensuring that your equipment's energy output is lossless and improving the final production line yield.

Ultimate size customization (value): Supports customization from a small light guide rod of Φ 1mm to a large light guide rod of Φ 100mm, perfectly matching the optical path cavity of your existing equipment without the need to modify the overall design.

High purity low hydroxyl (value): Low hydroxyl (<5ppm) or hydroxyl free products can be provided according to demand, effectively avoiding hydroxyl absorption peaks in the ultraviolet band and preventing the light guide column from overheating and causing equipment thermal runaway.

Application Cases

Background of the case: A well-known UV-LED curing equipment manufacturer in Southeast Asia.

Facing difficulties: When developing a new generation of high-power UV-LED surface light sources, customers initially used ordinary high borosilicate glass light guide columns. Under long-term full power operation, the light guide column exhibits severe heat absorption and yellowing phenomenon (glass structure changes caused by ultraviolet rays in the solar blind zone). Not only does the light conversion efficiency drop sharply from 85% to below 60%, but local high temperatures also cause the light guide column to explode, leading to equipment downtime and a surge in customer complaint rates.

Our solution:

Material selection replacement: Change the material to our customized low hydroxyl (<2ppm) optical grade quartz glass, completely eliminating the heat caused by UV absorption.

Structural optimization: Optimize the original straight through cylindrical design into a structure of "precision polishing at both ends+micro sanding on the side". The end face polishing ensures the incident/outgoing light rate, and the micro frosted surface on the side breaks the total reflection condition, allowing light to overflow uniformly from the side, successfully converting the point light source into a highly uniform surface light source.

Dimensional tolerance control: Control the length tolerance within ± 0.02mm to ensure perfect fit with the densely arranged LED array of the customer.

Final result: After switching to our quartz light guide column, the equipment operated continuously for 2000 hours under 350W high-intensity UV irradiation, with a transmittance attenuation of<1% and no thermal deformation.
