  • Patent number: 4865461
    Abstract: An apparatus for use in determining a thermal characteristic of a specimen includes first and second chucks for engaging two regions of the specimen, a first chuck mounting mechanism for supporting the first chuck in relatively fixed orientation, and a second chuck mounting mechanism. The second chuck mounting mechanism supports the second chuck in relatively movable orientation relative to the first chuck to permit variations in the spacing between the first and second chucks occasioned by thermal variations in the specimen. A base supports the first and second chuck mounting mechanisms. A laser is provided for heating a third region of the specimen lying between the two regions to a different temperature than the two regions. An infrared detector is provided for detecting radiation emitted from the third region.
