Heat resistant optical transparent JGS1 JGS2 fused silica plate

Heat resistant optical transparent JGS1 and JGS2 fused silica plates are special amorphous optical materials with high-purity silica as the core. JGS1 is a far ultraviolet grade synthetic quartz with ultra-high transmittance and extremely low impurities in the 185-2500nm wavelength range; JGS2 is ultraviolet grade gas refined fused silica, suitable for 220-2500nm wave band. Both have extremely low thermal expansion coefficients and excellent chemical stability, making them ideal substrates for dealing with extreme high temperatures, strong ultraviolet radiation, and high-precision optical system challenges. They support customized processing of full size specifications.

Frequently Asked Questions (FAQ)

Q1: How to select JGS1 and JGS2 fused silica plates in application?

A1: The selection mainly depends on your working wavelength and application scenario. If it involves deep ultraviolet (<220nm) lithography, excimer laser or extremely high purity requirements, it is recommended to choose JGS1; If mainly used in the conventional ultraviolet, visible to near-infrared bands (such as 220-2500nm) and pursuing high cost-effectiveness, JGS2 is an ideal choice.

Q2: How high temperature can this type of quartz plate withstand? Will sudden cold and heat rupture?

A2: Its softening point is above 1683 ℃, and it can work stably at high temperatures of 1100 ℃ for a long time. Meanwhile, thanks to its extremely low coefficient of thermal expansion (about 5.5 × 10 ⁻⁷/℃), it has excellent thermal shock resistance and will not explode even if quickly placed in cold water after heating.

Q3: Can we provide non-standard cutting, polishing, and coating services?

A3: Absolutely possible. We provide one-stop customized services from raw materials to finished products, including various irregular size cutting, high-precision surface polishing (such as λ/10 flatness), chamfering treatment, as well as customized coating services such as anti reflective film (AR) and high reflective film (HR).

Advantages and Application Value

To ensure the professionalism of material selection and the reliability of terminal equipment, our fused silica plate shows the following authoritative characteristics:

Extremely wide spectral transmission window: JGS1 has an average transmittance of over 90% in the 185-2500nm band, and JGS2 has a transmittance of over 85% in the 220-2500nm band, meeting the full spectrum transmittance requirements from deep ultraviolet to near-infrared.

Excellent thermal and mechanical stability: Mohs hardness of 5.5-6.5 and excellent Young's modulus. Under long-term high temperature or severe temperature differences, it can maintain extremely high dimensional accuracy and surface flatness, avoiding optical distortion caused by thermal stress.

Ultimate purity and chemical inertness: The metal impurity content is extremely low (JGS1 impurity ≤ 5 ppm), and except for hydrofluoric acid and hot concentrated phosphoric acid, it is almost not corroded by any acid or alkali, ensuring zero ion precipitation in a high cleanliness environment.

Flexible deep customization services: We provide cutting services covering various outer diameters, thicknesses, length and width dimensions, and are equipped with ISO certified precision polishing and coating workshops to fully ensure the integrity and safety of the process flow.

Directly addressing application challenges and customer cases

In actual high-end equipment manufacturing, many enterprises often face challenges such as strong laser thermal lens effect and fast ultraviolet attenuation. We have successfully resolved these challenges for numerous clients through our profound technical accumulation.

Customer application case: A well-known industrial laser equipment manufacturer

The company is facing severe technical challenges when developing a new generation of high-power ultraviolet laser marking machines: traditional optical window plates are prone to the "thermal lens effect" caused by absorbing heat when exposed to high-energy ultraviolet laser irradiation for a long time, resulting in beam focus drift and seriously affecting processing accuracy; And ordinary glass is prone to irreversible darkening at high temperatures. After receiving the demand, we customized the JGS1 level far ultraviolet fused silica window slice. Thanks to JGS1's extremely low hydroxyl content, ultra-high purity, and excellent UV damage resistance threshold, the new window not only ensures non-destructive penetration of UV laser energy, but also maintains perfect optical uniformity and structural stability under continuous high-intensity operation. In the end, the laser equipment successfully solved the problem of focus drift, greatly improving the yield and service life.
