Filter Glass

Filter Glass selectively transmits light (often over a specific range of wavelengths) and blocks the remainder of light. Advantages of filter glass include:

  • Many filter glass options (Band pass filters, Long pass filters, Short pass filters, Neutral density filters)
  • Precisely controlled composition and glass melting processes
  • Excellent homogeneity
  • Bubble and inclusion free
  • Affordability of filter glass compared to thin film coated filters
  • Durability of filter glass compared to thin film coated filters
  • Filter glass can be used as substrates for thin film coated filters

Applications of filter glass include

  • Astronomy
  • Digital imaging (CCD)
  • Displays (CRT, LCD, FED)
  • Fiber optics
  • High-power Laser Attenuators
  • Lighting
  • Machine Vision
  • Medical Devices
  • Night Vision
  • Optoelectronic devices
  • Photography
  • Protective eyewear (ex. for X-ray technicians)
  • Spectroscopy
  • Telecommunication
  • Filter glasses can be extremely beautiful and are also used in glass art
