Enviroptics SAPPHIRE WINDOW ASSEMBLIES/VIEWPORTS

SAPPHIRE OPTICAL WINDOW ASSEMBLIES

High purity sapphire is combined with a high temperature vacuum brazing process to produce a hermetically sealed window of extraordinary strength. The innovative use of proprietary brazes and joining technologies allows the creation of strong, durable, shock resistant components from a variety of dissimilar materials. The sapphire windows can be joined to various mounting flanges and corrosion resistant materials. These window assemblies are designed for applications that require wide temperature ranges, high pressures, scratch resistance, high thermal shock tolerance and a broad spectrum of frequency transmission at a high percentage of through-put.

SAPPHIRE OPTICAL VIEWPORTS

These viewports utilize a sapphire window brazed into a stainless steel or Hastelloy housing to produce a chemically durable viewport that can operate in harsh conditions including high and cryogenic temperatures as well as corrosive and abrasive atmospheres. Sapphire has excellent frequency transmission characteristics from ultraviolet through infrared.

FEATURES AND BENEFITS

• Hermaticity- Hermetically sealed sapphire windows exhibit a maximum leak rate of 1 X 10^-9cc helium/second
• Mechanical Strength- Sapphire has a burst strength many times greater than quartz or glass
• Thermal Characteristics- Operating range from +500ºC
  to -70ºC
• High Pressures- Pressures to 10,000 psi
• Chemical Inertness- Sapphire is more chemically inert than glass or quartz and is not affected by acids, strong alkalis or organic solvents
• Range of Frequency Transmission- Sapphire permits operation over a wide range of spectra from ultraviolet to infrared
