    Abstract: The present invention is directed to a pyrometer system and comprises an elevator tube. The elevator tube comprises an inner tube and an outer tube surrounding the inner tube in telescoping arrangement and extending from a top to a bottom thereof, the arrangement defining a fluid passageway therebetween. The elevator tube further comprises a port associated with the outer tube that is operable to transmit a cooling gas therethrough into the fluid passageway. A pyrometer head is coupled to the bottom of the inner tube and is operable to transmit and receive radiation through the inner tube. The system further comprises a spider collar coupled to at least one of a top of the inner tube or outer tube, and is operable to support a work piece for thermal measurement thereof. In another embodiment, a sleeve having a coefficient of thermal expansion is provided at the top portion of the elevator tube, so that temperature dependent changes in the focal length of a lens associated with the sleeve are compensated.
