    Abstract: A method for adjusting a focus position of an inspection apparatus includes measuring, while varying a height position of a pattern forming surface of an evaluation substrate with thereon plural types of figure patterns, for each type of figure pattern, light amounts at front and back focus positions of a light transmitted through or reflected from the evaluation substrate irradiated with an inspection light, calculating an autofocus signal, for each type of figure pattern and for each height position of the pattern forming surface, by using the light amounts measured at the front and back focus positions, and specifying a value of an inspection autofocus signal such that a difference between autofocus signal values of plural type figure patterns calculated at the same height position of the pattern forming surface is equal to or less than a threshold value.

    Abstract: Laser induced breakdown spectroscopy (LIBS) devices for analysis of geological and related samples, and related methods. In the method, a scanning table having a geological core is moved from a start position to an end position for each position in a plurality of positions of the scanning table corresponding to an e region of interest of the geological core. At each position, laser ablation is performed on the exposed surface of the geological core using an oscillating planar focus laser. Contemporaneously with performing laser ablation on the exposed surface of the geological core, spectroscopy is permitted on the emitted light received by a fiber optic receiver sharing an optical path with the oscillating planar focus laser.

    Abstract: There are provided an overlay measuring device and a method for controlling a focus and a program therefor. An overlay measuring device controlling a focus in one embodiment includes an objective lens; a memory; a lens focus actuator operating the objective lens to adjust a distance between the objective lens and a wafer; and a processor controlling operations of the memory and the lens focus actuator, wherein the processor is configured to obtain a first height value in relation to each site of the wafer, match the obtained first height value and a corresponding site and store the same, and as initial measurement in relation to each site of the wafer starts, control the lens focus actuator, based on the stored first height value of the site, to control a Z-axis movement of the objective lens.

    Abstract: A system for the detection of foreign object debris material on a surface of a composite part being manufactured. A platform is configured to move over the surface. A thermal excitation source is fixed to the platform and configured to direct infrared radiation across the surface. An infrared camera is also fixed to the platform and configured to scan the surface as the platform moves over the surface to detect and output a signal proportional to infrared radiation emitted by the surface and/or by any foreign object debris material on the surface in response to the infrared radiation from the excitation source. A controller is coupled to the excitation source and to the infrared camera and is configured to compare the signal from the infrared camera with a first predetermined threshold signal to detect if any foreign object debris material is located on the surface.

    Abstract: A high-throughput optical suspension characterization instrument is disclosed, which can include hydraulically separate and at least partially transparent sample containers. A selection mechanism is operative to selectively direct light from a light source (12) through different ones of the sample containers along an optical axis, and an off-axis scattering detector (38,24) is responsive to scattered light from the light source after it has interacted with a sample. Phase analysis light scattering is used to determine the electrophoretic mobility and zeta potential of samples. A second instrument is disclosed, wherein all sample containers are illuminated simultaneously. Transmitted light is collected by a camera. The electrophoretic mobility and hydrodynamic size of the samples may be determined.
