Method and device for photothermal investigation of a sample
摘要
<p>The device (10) comprises an excitation source (14,20,22) for generating an electromagnetic excitation beam directed onto an excitation side of a sample (12), and a detector (28) for detecting thermal radiation (26) emitted by a detection side of the sample. A temperature controllable sample chamber (36) with a sample holder (13) is provided for the arrangement and temperature control of the sample. An adjustable detection lens is provided between the sample holder and the detector, which is adjustable for adjusting a field of vision of the detector on the sample surface. An independent claim is included for a method for photothermal investigation of a sample.</p>
