High purity transparent optical quartz plates are widely used in various precision optical instruments, laser technology, and medical equipment due to their excellent transmittance in the deep ultraviolet to near-infrared wavelength range (185nm-3500nm).

What are you most concerned about about about optical quartz plates?

Q: My device requires deep ultraviolet light for lithography, which ordinary glass cannot meet. What should I do?

Answer: Our high-purity transparent optical quartz plate has a transmittance of over 85% in the 185nm deep ultraviolet band, solving your energy loss problem in UV lithography and spectral analysis.

Q: Optical experiments require extremely high material purity. How to avoid signal interference caused by impurities?

Answer: We use high-quality natural crystals or high-purity synthetic silicon materials as raw materials. The total metal ion content of the product is less than 50ppm, and the bubble and stripe levels reach the optimal level 0, ensuring that the optical signal is pure and interference free.

Q: I need non-standard size and irregular opening quartz plates. Can customization be supported?

Answer: Of course. We support customization from a diameter of 5mm to 500mm, providing precision machining such as drilling, steps, chamfering, etc. to meet your installation needs for special fixtures or vacuum chambers.

Why is optical quartz plate your ideal choice?

1. Excellent transmittance and wide spectral range

High purity transparent quartz glass has extremely high energy penetration ability in both the ultraviolet and infrared regions. Its transmittance curve is straight, avoiding the absorption peak problem of crystalline materials in specific bands, making it an ideal substrate for spectrophotometers and laser window plates.

2. Extremely low impurities and high damage resistance threshold

Through strict control of the melting process, our quartz plates have a uniform and dense internal structure. The direct advantage this brings is:

-High temperature resistance: The softening point temperature can reach up to 1730 ℃, and it can withstand continuous high-power laser irradiation.

-Thermal shock resistance: Its extremely low coefficient of thermal expansion makes it less prone to rupture under severe temperature differences.

-Chemical stability: resistant to most acid-base corrosion except hydrofluoric acid, suitable for harsh chemical environments.

3. Flexible non-standard customization capability

We are well aware that 'standard products' cannot meet the integration needs of all high-end devices. We provide a complete customized chain from raw materials to finished polishing and coating, truly achieving "processing according to drawings and precise delivery".

Determining factors and application scenarios of translucency

The physical essence of translucency

The transparency of high-purity quartz glass is mainly determined by its internal structure. Due to its network structure composed of silicon oxygen tetrahedra and no grain boundary scattering, quartz glass has high transparency. Our product eliminates hydroxyl (- OH) content through technology, significantly reducing the infrared absorption peak of the material around 2700nm, ensuring the availability of the infrared band.

Typical application scenarios

1. Semiconductor lithography and detection: As a photomask substrate or lens material, it requires extremely high ultraviolet transmittance to ensure fine transfer of circuit patterns.

2. Laser protection and processing: As the output window of high-power lasers, an extremely low absorption coefficient is required to prevent the window from overheating and exploding.

3. Research and Medical: In PCR fluorescence quantitative detection and DNA analyzer, as a microfluidic chip substrate, it is required to have no background fluorescence interference to ensure detection accuracy.

Customer application case: Assisting in the implementation of global scientific research projects

Case background:

A top European optical research institute located in Germany is developing a new generation deep ultraviolet Raman spectrometer. The original plan was to purchase synthetic quartz window panels from a Japanese brand, but faced a delivery cycle of up to 16 weeks and the inability to provide special wedge angles, which seriously slowed down the project progress.

Requirement analysis:

The customer urgently needs a batch of high-purity quartz window plates with a size of Φ 25.4mm (1 inch), a thickness of 3mm, and a 30 minute wedge angle. They require a transmittance of not less than 82% at a wavelength of 193nm and a surface roughness of<0.5nm to prevent scattered light from affecting weak signal acquisition.

Our solution:

1. Material selection: We recommend using JGS1 grade synthetic quartz, which has excellent deep ultraviolet transmittance and no fluorescence effect.

2. Precision machining: Using five axis precision machining equipment, strictly control the wedge angle tolerance within ± 2 minutes. Using magnetorheological polishing technology to achieve a surface roughness of 0.4nm.

3. Fast delivery: From confirming the drawings to completing production, it only took 10 working days and was expedited by air freight, delivering 5 weeks earlier than originally planned.

Final effect:

After receiving the product, the customer provided feedback that the performance of the quartz window plate in the deep ultraviolet band fully met expectations, with a 15% increase in instrument signal-to-noise ratio. The project team leader stated, "This not only saves us the time we wasted waiting for materials, but its optical quality is even better than our initial goal." Currently, the research institute has listed this specification product as a standard selection for its subsequent projects.
