Q: As an optical instrument manufacturer or R&D personnel, do you face the following challenges?

Do you need materials with high transmittance and low thermal expansion to ensure the accuracy of optical systems?

Worried about the performance degradation of optical components caused by UV or high temperature environments?

Looking for corrosion-resistant and highly stable window or substrate?

Do you need customized sizes and shapes to accommodate special instrument designs?

Answer: Customizing quartz plates is your ideal solution. It can provide over 99% high transmittance (from ultraviolet to infrared bands), almost zero thermal expansion coefficient, and excellent chemical stability, directly solving the core requirements of optical instruments for material accuracy, environmental resistance, and long-term reliability.

In the design and manufacturing of modern optical instruments, the selection of core optical components directly determines the performance, accuracy, and reliability of the instrument. Quartz plate (quartz glass plate), as a high-performance optical material, has become one of the preferred choices for high-end optical instruments.

Key applications of quartz plates in optical instruments

Quartz plate is an optical material mainly composed of high-purity silicon dioxide (SiO ₂), which is made through precision melting and processing. In optical instruments, it is widely used in the following scenarios:

-Optical window and protective film: used as observation windows for spectrometers, microscopes, laser equipment, and other instruments to protect internal components from environmental erosion.

-Lens and Prism Substrate: Used as a substrate for lenses, prisms, and reflectors in ultraviolet, visible, and infrared optical systems.

-Precision optical platform: an optical platform used for high-precision instruments such as interferometers and lithography machines to ensure stable optical path transmission.

-Sensor packaging: Provides transparent and durable packaging protection for optical sensors in high temperature or corrosive environments.

Advantages of Quartz Plates: Why is it an ideal choice for optical instruments?

High transparency and wide spectral range

Quartz plates have excellent transparency in the ultraviolet (UV), visible light to near-infrared (IR) bands (usually UV grade quartz has a transmittance of over 90%). This makes it suitable for full spectrum optical systems, especially irreplaceable in ultraviolet laser equipment and astronomical observation instruments.

Excellent thermal stability and low thermal expansion coefficient

The thermal expansion coefficient of quartz is extremely low (about 5.5 × 10 ⁻⁷/℃), and it can maintain stable shape and optical properties at high or sudden temperature changes. For example, in high-temperature microscopes or aerospace optical equipment, quartz plates can avoid aberrations caused by thermal deformation.

Excellent chemical durability and mechanical strength

Quartz plate is acid and alkali resistant, corrosion-resistant, and not easily aged in humid or chemically exposed environments. Its hardness is high (Mohs 7), and the surface can be polished to achieve optical grade flatness (roughness<1nm), making it suitable for precision optical coating.

High laser damage threshold

For high-power laser systems such as laser cutting machines and optical radars, quartz plates can withstand high energy densities to avoid performance degradation caused by laser burns.

The core problem solved by quartz plate

-Poor environmental adaptability: Ordinary optical glass has a high absorption rate in the ultraviolet band and is susceptible to chemical corrosion. Quartz plates make up for this deficiency and expand the application range of instruments in special environments.

-Thermal deformation leads to decreased accuracy: In laboratory or industrial scenarios with large temperature fluctuations, the low thermal expansion characteristics of quartz plates ensure the long-term stability of optical systems.

-Short service life: the abrasion resistance and anti-aging characteristics of quartz plate extend the maintenance cycle of optical instruments and reduce the operating cost.
