Abstract
A method is provided to extend the high temperature and/or high pressure operating range of a primary radiation-transmitting element 5,6 by the addition of a secondary enclosure 15,16 for containing a pressurized gas atmosphere and a secondary radiation-transmitting element 23,24 wherein the primary radiation-transmitting element 5,6 experiences a reduced pressure differential.
Claims9
A method of reducing the pressure differential across a primary optical element of a fluid containment vessel having a cavity therein partially defined by said optical element for receiving a sample, said cavity being subjected to a predetermined pressure, comprising the following steps:
- providing an external gas pressurizable enclosure adjacent an exterior of said optical element;
- and
- pressurizing said enclosure to a pressure approaching said predetermined pressure so as to minimize the pressure differential across said optical element.
A device for enabling spectroscopic examination, comprising:
- a cell body having a cavity therein;
- a first optical element secured to said cell body and partially defining said cavity, said cavity being on an internal side of said first optical element;
- means for introducing gas into a removing gas from said cavity so as to pressurize said cavity to a predetermined pressure;
- and
- means for pressurizing an external side of said first optical element so as to reduce the pressure differential across said first optical element, said pressurizing means including a second optical element.
A means for supporting a primary radiation-transmitting element which is subject to high temperatures and high pressures, comprising a secondary enclosure for containing a pressurized gas atmosphere and which incorporates a secondary radiation-transmitting element, wherein the primary radiation-transmitting element experiences a reduced pressure differential.
