As an ideal material in the field of general ultraviolet optics, JGS2 quartz sheet perfectly combines excellent optical performance with high cost-effectiveness, making it the preferred substrate for various precision optical instruments.

FAQ

Q1: What are the main differences between JGS2 quartz sheet and JGS1, JGS3?

A: The main difference lies in the transmission band and impurity content. JGS1 is suitable for deep ultraviolet (185-2500nm) with extremely high purity; JGS2 is suitable for general ultraviolet to near-infrared (220-2500nm), with high cost-effectiveness; JGS3 is specifically designed for the infrared band (260-3500nm). JGS2 is an ideal choice for most conventional ultraviolet and visible light optical applications.

Q2: What size and precision customization services can you provide?

A: We support highly flexible customized services. The diameter/size range can be from 5mm to 300mm, and the thickness supports 0.5mm to 50mm. The surface accuracy can reach λ/4 to λ/10, and the surface quality can reach 60/40 or higher. Simultaneously supporting coating requirements such as anti reflective film (AR) and reflective film, as well as deep processing such as irregular cutting, punching, and chamfering.

Q3: What is the high temperature resistance and corrosion resistance of JGS2 quartz sheet?

A: The softening point of JGS2 quartz sheet is as high as 1730 ℃, which can work stably in an environment of 1100 ℃ for a long time and has extremely strong thermal shock resistance (no explosion during rapid cooling and heating). In terms of chemical stability, except for hydrofluoric acid and hot concentrated phosphoric acid, it can withstand the corrosion of most strong acids, strong bases, and organic solvents.

Requirements and Problem Solving

For users who are looking for high stability optical substrates, JGS2 quartz sheets can perfectly solve the core problems of ordinary optical glass, such as high absorption rate in the ultraviolet band, easy deformation or explosion in high temperature environments, and lack of chemical corrosion resistance. Whether used for harsh industrial environment observation windows or precision detection equipment with extremely high requirements for optical path stability, it can provide you with excellent optical transparency and physicochemical stability, ensuring the long-term reliable operation of your equipment.

Customer application case sharing

Case 1: Customized Window sheets from a Renowned Spectral Analysis Instrument Manufacturer

Customer challenge: The new portable spectrometer developed by the customer needs to work in complex outdoor temperature difference environments. The original ordinary glass window is prone to micro cracks when quickly switching from low to high temperature, and it absorbs ultraviolet light below 300nm severely, resulting in a significant decrease in detection accuracy.

Solution: We recommended a quartz window sheet made of JGS2 material and customized a circular thin sheet with a diameter of 50mm and a thickness of 2mm based on the internal structure of the instrument. By double-sided precision polishing (with a surface accuracy of λ/4), and coating with an anti reflective film in the 200-400nm wavelength range.

Application effect: After replacing the JGS2 quartz window, the instrument showed extremely stable performance in severe temperature difference tests between -20 ℃ and 60 ℃, without any risk of explosion. At the same time, the signal transmittance in the ultraviolet band has increased by more than 15%, greatly improving the detection accuracy of the equipment and its adaptability to outdoor environments.

Case 2: Align the optical path of a semiconductor equipment company with the substrate

Customer challenge: In the packaging process of optical communication devices, customers require a substrate with extremely high flatness and excellent thermal stability to secure micro lenses and optical fibers. Although the original ceramic substrate is heat-resistant, its processing accuracy is difficult to reach the micrometer level, and it is not conducive to real-time alignment observation of the optical path.

Solution: We have utilized the excellent processing performance and low expansion characteristics of JGS2 quartz glass to process a batch of optical substrates (step sheets) with micrometer level steps and positioning grooves for our customers. The surface has undergone ultra precision polishing, ensuring extremely high flatness and cleanliness.

Application effectiveness: JGS2 quartz substrate perfectly solves the problem of multi optical path coupling alignment for customers. Its high transparency allows engineers to directly observe the bottom light path through the substrate, and the micrometer level processing accuracy ensures assembly consistency, greatly improving the integration efficiency and product yield of customer production lines.
