Gas Cooled Endoscope Shell

Thoughtventions Unlimited, LLC, offers the Model 022, air-cooled probe shroud that allows the use of standard borescopes in high temperature, high pressure, and corrosive environments.  The Model 022 probe shroud has a hermetically sealed sapphire window that is noble-metal brazed into a 300 Series stainless steel housing.   The sapphire window permits an enclosed borescope to have a field of view of over 120 degrees and provides excellent transmission from the UV to the IR.   Optical probes of up to 5/16 inch diameter can be inserted into the standard probe shroud; custom sizes are available.
