Product Definition: What is high light transmittance UV quartz plate?

High-transparency UV quartz plate is an optical-grade plate made from high-purity natural quartz sand (with a SiO₂ content typically above 99.99%) through high-temperature melting, precise annealing and modern cold working techniques. Its core feature lies in its extremely high transmittance to ultraviolet (UV) rays, especially deep ultraviolet (DUV) bands (typically above 85%, up to 93% @185nm), while also possessing excellent thermal stability, chemical inertness and mechanical strength.

Core advantage: Why choose our UV quartz plate?

1. Ultimate optical performance

High ultraviolet transmittance: It has excellent transmission performance in the wide spectral range of 190nm to 2500nm, making it an ideal window material for applications such as UV curing, lithography, and sterilization.

Low autofluorescence: The raw materials are pure and the processing is strictly controlled to ensure that the self-fluorescence background of the sheet is extremely low, avoiding interference with the precision optical detection system.

Optical uniformity: Uniform refractive index distribution ensures that the waveform is not distorted when light passes through, resulting in clear imaging.

2. Excellent physical and chemical stability

Thermal shock resistance: It has an extremely low coefficient of thermal expansion and can withstand drastic temperature changes without cracking (such as a sudden drop from 1000 ° C to room temperature).

Corrosion resistance: It has excellent corrosion resistance to the vast majority of acids, alkalis and organic solvents, except for hydrofluoric acid and hot phosphoric acid.

High hardness and wear resistance: With a Mohs hardness of up to 7, the surface is not easily scratched and has a long service life.

3. Precise customized processing capabilities

We can provide a series of precision processing services such as cutting, drilling, chamfering, grinding and polishing according to your drawings or requirements.

It has a wide range of processable dimensions, and key indicators such as thickness tolerance, flatness, and parallelism can all meet strict optical grade standards.

Problem-solving: What key challenges can UV quartz panels address?

Can ordinary glass/optical glass not transmit deep ultraviolet rays?

The UV quartz plate is a "transparent window" in the 185nm-350nm band, solving the problem that the energy of UV light sources cannot be efficiently utilized.

Does a high-temperature or sudden temperature change environment cause the observation window to crack or deform?

The extremely high heat resistance of the quartz plate ensures the stable operation and safe observation of the equipment in harsh thermal environments.

Strong corrosive environments erode equipment components?

As a corrosion-resistant barrier, quartz plates can effectively protect the precise optical or electronic components inside.

Need high-purity and pollution-free materials to contact the samples? Quartz material has excellent chemical inertness and will not contaminate reactants or products, making it the preferred choice in fields such as semiconductors and life sciences.

Application scenarios: In which fields do UV quartz plates shine brightly?

1. Semiconductors and integrated circuits: Photomasks for photolithography machines, observation Windows for CVD/PVD equipment, wafer carriers. Its high UV transmittance and low thermal expansion characteristics are the key to ensuring the accuracy of lithography and the stability of the process.

2. UV Curing and Printing: UV-LED curing equipment, ultraviolet transmission plates for printing machines, exposure machines. Ensure that ultraviolet energy is efficiently and evenly projected onto the cured material.

3. Medical and Biological Sciences: Lamp tube sleeves for ultraviolet sterilization equipment, observation Windows for biosafety cabinets, and optical components for DNA analysis instruments. It features high light transmittance, disinfection resistance and biocompatibility.

4. Industry and scientific research: Observation Windows for high-temperature furnaces, sample cells for spectrometers, optical substrates for laser equipment, and gas chamber Windows for environmental monitoring instruments.

Customer Case (anonymous) :

Case One (a German semiconductor equipment manufacturer) : The customer requires a substrate for a new type of photolithography machine, which demands a transmittance of over 90% for 193nm ArF excimer laser and an extremely low coefficient of thermal distortion. By optimizing the smelting process and adopting ultra-precision polishing technology, the quartz plates we provide fully meet its strict indicators and have been stably supplied for over three years.

Case Two (A certain medical device company in the United States) : The client developed a portable UV sterilization device and needed to customize quartz lamp tubes with complex shapes, thin walls and high light transmittance. We successfully solved the problem of its fragility during processing and achieved mass production, helping our customers' products successfully enter the market.
