Advantages of High Transmittable Optical Quartz Glass Disc

Corrosion resistance
The glass disc especially quartz can resist acid and alkali. The quartz do not react with any acid, except hydrofluoric acid.

High working temperature
The soda-lime glass discs can work under 450 °C high temperature and the quartz glass discs can even work under 1200 °C for a long time.

High light transmittance
The quartz transmittance can reach 95%.

Polished surface
There is no bubble or scratch and the surface is flat, clear and polished.

Perfect edging handling
The edge is exactly round. It can be ground and polished. The polished edge is more smooth.

Applications of High Transmittable Optical Quartz Glass Disc

Semiconductor Manufacturing

Its purity and thermal stability are critical in processes like the Czochralski method for growing silicon crystals.

Optics and Photonics

Fused quartz is used in lenses, mirrors, and windows for systems requiring high UV and IR transmission.

Lighting

Due to its ability to withstand high temperatures and transmit UV light, it’s used in halogen and HID lamp envelopes.

Laboratory Equipment

Its chemical resistance and thermal properties make it ideal for crucibles, beakers, and other labware.

Aerospace and Defense

Fused quartz is employed in spacecraft windows and protective covers due to its strength and thermal resistance.

UV Sanitation Systems

Its UV transparency is utilized in sterilization and disinfection equipment.

Package and transportation

One piece in a plastic bubble bags and 100 bags in a carton and 10 cartons in a wooden case.
According to customers' requirements.

FAQ

Q: Where are quartz discs used?

A: They are common in semiconductor processing and furnace components. In addition, they serve as windows, lenses and sight glasses in optical and lab equipment.

Q: What sizes are available?

A: Standard sizes range from 10 mm to 200 mm in diameter with 1–10 mm thickness. Custom dimensions can also be supplied on request.

Q: How much heat can quartz discs handle?

A: They withstand continuous heat up to 1,050 °C and short bursts up to 1,200 °C. Therefore, they are reliable for high-temperature systems.

Q: Are quartz discs suitable for optical systems?

A: Yes. They offer excellent transmission from deep UV to IR and, moreover, can be coated for even better optical performance.

Q: How do quartz discs compare to glass discs?

A: Unlike regular glass, fused silica quartz discs can handle higher heat, have lower thermal expansion, and resist chemicals better. They also offer superior optical clarity, especially in the UV and IR spectrum.

Q: Can I order custom quartz discs?

A: Absolutely. Custom quartz discs can be made with specific diameters, thicknesses, drilled holes, edge polishing, or coatings depending on your requirements.

Q: How can i get the price?

A: We usually quote within 24 hours after we get your inquiry(Except weekend and holidays). If you are very urgent to get the price, please email us or contact us in other ways so that we can offer you a quote.
