Probe Bodies | Shrouds with brazed Sapphire Optical Windows

Written by Enviroptics on 17 September 2011

Probe bodies with brazed hermetically sealed

high purity synthetic sapphire windows are now available from Enviroptics Inc. These

sealed bodies are designed and tested to perform under harsh conditions including high

and cryogenic temperatures, corrosive conditions and abrasive atmospheres. Sapphire

is the window of choice for these bodies/shrouds because of its high percentage of

optical transmission from UV through visible to infra red frequencies. The shrouds are

available off-the-shelf or in custom configurations in a wide variety of materials such as

Hastelloy C276, Titanium and 316 Stainless that are suitable for harsh environment

applications.

BENEFITS

 Hermetically sealed to 1 X 10 -9 cc. helium

 High pressures to 1000 psi

 Temperatures from +500º C to -150º C

 Sapphire has a high melting point of 2040º C

 Sapphire does not react with chemicals up to 300º C

DESIGNED SPECIFICALLY FOR HARSH ENVIRONMENTS

High purity synthetic sapphire windows are vacuum brazed to a wide range of metals,

the result is a window assembly that is unaffected by high or cryogenic temperatures,

high pressures, corrosive or abrasive atmospheres.
