What is the transmission spectrum of JGS1?

Transmission Spectrum of JGS1

JGS1, also known as Synthetic Fused Silica, is a type of pure silica glass that is widely used in various optical applications due to its excellent transmission properties, especially in the ultraviolet (UV) to the near-infrared (NIR) spectrum. The transmission spectrum of JGS1 is characterized by its high transmittance over a broad wavelength range, making it an ideal material for UV optics, lenses, and other optical components.

Key Features of JGS1 Transmission Spectrum

  • High UV transmittance: JGS1 exhibits high transmission rates starting from as low as 185 nm, making it suitable for deep UV applications.
  • Extended transmission into the NIR: It maintains good transmittance up to 2500 nm, covering the entire visible spectrum and extending into the near-infrared region.
  • Low absorption: JGS1 has minimal absorption bands in the visible spectrum, ensuring clear and undistorted transmission of light.

Transmission Rates

The transmission rates of JGS1 can vary slightly depending on the thickness of the material and the presence of impurities. However, it typically exhibits transmission rates of over 90% in the 200 nm to 2,000 nm wavelength range for a 10 mm thick sample. The transmission drops significantly below 185 nm due to absorption by the material.

Applications

Due to its broad transmission spectrum and high UV transmittance, JGS1 is extensively used in:

  • UV lithography systems
  • Optical lenses and windows
  • High-power laser applications
  • Spectroscopy instruments

Its ability to transmit UV light efficiently while maintaining high transmittance in the visible and NIR regions makes JGS1 a versatile material for a wide range of optical applications.
