JGS1
Commonly known as UV-grade fused silica, this material exhibits exceptionally low dispersion and very high transmittance in the ultraviolet (UV) spectral range.
JGS2
Similar to JGS1, but may have variations in specific performance parameters such as transmittance and thermal expansion coefficient, depending on the manufacturer’s standards.
JGS3
Typically used in applications requiring higher purity or specialized performance characteristics. Specific performance parameters can vary based on the manufacturer.
Dispersion Characteristics
JGS1 and JGS2 quartz sheets exhibit excellent dispersion properties in the ultraviolet (UV) spectral range, effectively separating UV light of different wavelengths. This makes them ideal for manufacturing high-performance optical components.
Transmittance
All three types of quartz sheets have high transmittance to UV light, especially within specific wavelength ranges. For example, JGS1 has very high transmittance from 185 nm to 2,500 nm. This makes them the preferred materials for manufacturing UV lasers, UV spectrometers, and optical filters.
Chemical Stability
Quartz sheets possess excellent chemical stability and can withstand harsh conditions, including acids, alkalis, and high temperatures. Therefore, they are suitable for manufacturing chemical reactors, high-temperature furnace windows, and chemical analysis instruments.
Low Thermal Expansion Coefficient
These quartz sheets have very low thermal expansion coefficients, exhibiting minimal response to temperature changes. This is crucial for the stability of high-precision optical components.
Сценарий применения
Quartz sheets exhibit excellent high-temperature resistance, corrosion resistance, thermal stability, and light transmittance. Its softening point is approximately 1730°C, and it can be used continuously at 1100°C, with short-term usage up to 1450°C. Quartz glass is highly resistant to acids, with the exception of hydrofluoric acid, and demonstrates high resistance to chemical reactions with most other acids. Quartz sheets have a very low thermal expansion coefficient, enabling them to withstand rapid temperature changes without fracturing. They also exhibit good light transmittance across the entire UV to IR spectrum, with a visible light transmittance exceeding 93%.
Based on optical properties, quartz sheets are classified into three categories: far-ultraviolet (FUV) optical quartz glass (JGS1), ultraviolet (UV) optical quartz glass (JGS2), and infrared (IR) optical quartz glass (JGS3). These different types of quartz glass exhibit variations in transparency, absorption band positions, etc., in the UV and visible spectral ranges.
The processing of quartz sheets includes rough processing steps such as raw material sorting, rod bonding, seed crystal cutting, and rounding. This is followed by grinding stages, such as rough grinding, medium grinding, and fine grinding. Afterwards, polishing and cleaning processes are conducted to ensure surface quality and stability of the wafers. Finally, mounting and die-bonding involves fixing the quartz sheets with applied electrodes and applying conductive adhesive to the contact points between the electrodes and metal pads to achieve electrical connection.
Часто задаваемые вопросы
Кварцевое стекло - это твердый и хрупкий материал с отличными физическими и химическими свойствами, чрезвычайно высокой механической твердостью, хорошей электроизоляцией, высокой температурой и коррозионной стойкостью, низкой и стабильной задержкой, хорошим светопропусканием и т.д. Он широко используется в полупроводниках, оптике, электричестве, химии, аэрокосмической промышленности, автомобилестроении и других областях. Твердые и хрупкие материалы трудно поддаются обработке, поэтому во многих областях срочно требуются процессы резки с небольшим разрушением кромок, меньшими потерями материала, низкой шероховатостью поперечного сечения и широким диапазоном толщины реза. Традиционным методом резки кварцевого стекла является механическая резка, то есть резка кругом. К нетрадиционным методам резки относятся водоструйная резка, резка проволокой электрохимического разряда, непрерывная лазерная резка и т. д. Механическая резка имеет низкую стоимость, но контакт между кругом и материалом приводит к большому износу инструмента, а материал легко загрязняется инструментом. Кварцевое стекло подвержено разрушению кромок, микротрещинам и остаточному напряжению, что влияет на прочность и эксплуатационные характеристики материала! Трудно добиться криволинейной резки и требуется последующая обработка, такая как шлифовка и полировка. Лазерная резка не контактирует непосредственно с материалом, не имеет контактного напряжения и может выполнять сложную криволинейную резку. Пикосекундный лазер обладает такими преимуществами, как малый диаметр пятна, высокая точность, короткое время воздействия на материал и малая площадь воздействия, и подходит для обработки твердых и хрупких материалов.
