Probe Bodies | Shrouds with brazed Sapphire Optical Windows

Enviroptics — Sat, 17 Sep 2011 19:51:33 +0000

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 C, Titanium and 316 Stainless that are suitable for harsh environment applications.

BENEFITS

Hermetically sealed to 1 X 9-9 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
