Fused Quartz optical Dome

optical Dome


  • Dome is a protective window with hemispherical shell shape. It is often used in the application of incident light in large angle range, such as detector, optical sensor and so on.

  • Quartz glass is an ideal UV material. It has high transmittance in the range of 220nm to 2500nm, good chemical stability and radiation resistance, low expansion coefficient, low fluorescence radiation and scratch resistance.
