Our portfolio includes more than 200 different glass compositions, engineered for optimal performance in varying applications with spectral capabilities extending from ultraviolet (UV) to infrared (IR) regions of the spectrum.

Borosilicate Glass


We have a variety of borosilicate glass compositions available including clear and colored compositions, special low thermal expansion borosilicate, ultraviolet (UV) absorbing amber glasses, and ultraviolet (UV) transmitting borosilicate glasses. Borosilicate glass is the preferred material for many industrial and scientific applications because of the following properties:

  • Chemical Durability: Highly resistant to chemical corrosion
  • Mechanical Durability: Offers best abrasion resistance and high compressive strength
  • Thermal Stability: Heat resistant and can handle extreme temperature differentials
  • Ultraviolet (UV) Stability: Glass will not degrade or "yellow" from sunlight exposure
  • Transmission Properties: Consistent light transmission that will not change or decrease over time like most polymers


We have a complete portfolio of colored glass formulations designed to meet industry and regulatory standards, including:

  • Federal Aviation Administration (FAA)
  • Military (MIL) Specifications
  • International Civil Aviation Organization (ICAO)
  • American Association of Railroads (AAR)
  • Institute for Traffic Engineers (ITE)

Our colored glass portfolio includes filter options designed for compatibility with specific light sources including white and colored light emitting diode (LED), plasma, HID, and incandescent.

Night Vision Imaging Systems (NVIS)


We are the industry leader for night vision goggle (NVG) compatible monolithic filter glass. Our product line is designed to meet MIL-STD-3009 color requirements with LED and incandescent sources.

Our product line was engineered to meet narrowed ranges within the acceptable color specifications resulting in a superior filter product line with consistent and uniform spectral properties.

Our line of NVIS compatible filter solutions includes:

  • Secure Blue-Green
  • NVIS Green A
  • NVIS Green A (Intruder)
  • NVIS Green B
  • NVIS Yellow B
  • NVIS White
  • NVIS Friendly
  • Covert (IR Transmitting / Visible Absorbing)
