Optical Windows: Features and Applications of Fused Quartz Windows

Product Overview of Fused Quartz Windows

Fused quartz windows are transparent plates designed to transmit light beams from one environment to another while preventing the mixing of environmental elements. They maintain the wavelength and wavefront of the transmitted light and prevent beam divergence. These windows are commonly used to protect electronic sensors and other optical systems from environmental influences.

Characteristics of Fused Quartz Windows

High Precision and Clear Transmittance: Ideal for stringent applications with low volume scattering and spontaneous fluorescence.
Exceptional Surface Quality and Parallelism: Ensures efficient light transmission.
Low Thermal Expansion Coefficient and Refractive Index: Compared to N-BK7, fused quartz offers better uniformity, lower thermal expansion, and lower refractive index, making it suitable for applications requiring good transmittance into the UV range.

Application Areas of Fused Quartz Windows

Protection of Electronic Sensors: Shields sensors from environmental effects while allowing light to enter the instrument.
Optical Systems: Used to separate two chambers, minimizing reflection and absorption of light.
Solar and Semiconductor Industries: Suitable for light transmission between 220 and 2500nm.

Substrate Options of Fused Quartz Windows

UV, IR, Vis, or Broadband Spectra: Various substrate choices for different spectral range applications.
High Purity and Uniformity: Fused quartz has high purity and uniformity, ideal for transmission in the deep UV range.
UV-Grade Fused Quartz: Equivalent to Corning 7950 or Heraeus Suprasil 1 and 2, with no absorption band in the 170-250nm range and a strong OH absorption band at 2600-2800nm.
