Abstract: Compact thermal sensor modules, which in some implementations can be manufactured in wafer-level fabrication processes, include features composed of or coated with a low-emissivity material to reduce or prevent detection by a sensor of radiation emitted by other parts of the module. For example, spacers that separate an optics substrate and a sensor package from one another can be composed of or coated with such a low emissivity material. In some cases, the low emissivity material has an emissivity of no more than 0.1.

Abstract: The embodiments of the present invention are directed to applying intimate contact pressures to samples while undergoing ATR infrared interrogation. As a general mode of operation, after a solid sample is placed on the ATR element, a force actuator moves an anvil arm to apply a contact force to the sample against the ATR.

The applied contact force may be a fixed force or may be a user-selectable force or may be automatically controlled through feedback from the spectrometer based on the spectroscopic signature of the sample material.

Abstract: This disclosure presents systems for total reflection x-ray fluorescence measurements that have x-ray flux and x-ray flux density several orders of magnitude greater than existing x-ray technologies. These may therefore useful for applications such as trace element detection and/or for total-reflection fluorescence analysis. The higher brightness is achieved in part by using designs for x-ray targets that comprise a number of microstructures of one or more selected x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment of the targets with higher electron density or higher energy electrons, which leads to greater x-ray brightness and therefore greater x-ray flux. The high brightness/high flux source may then be coupled to an x-ray reflecting optical system, which can focus the high flux x-rays to a spots that can be as small as one micron, leading to high flux density.
