Abstract: The invention relates to a photometer (30) for analysing the composition of a sample gas. The photometer comprises an infra-red (IR) source (20) configured to direct a first plurality of pulses (40) of IR radiation through the sample gas to an IR detector (26), at least two of the first plurality of pulses being of different wavelength. The photometer further comprises an ultraviolet (UV) source (32) configured to generate a second plurality of pulses (38) of UV radiation for conveyance to a UV detector (36), at least two of the second plurality of pulses being of different wavelength. A path selection arrangement (22, 42-50) is configured to selectively convey different ones of the second plurality of pulses (38) to one of the sample gas and the UV detector (36). The photometer further comprises processing circuitry coupled to the IR source (20), the UV source (32), the IR detector (26), the UV detector (36) and the path selection arrangement (22, 42-50). The processing circuitry is configured to (i) select the wavelength to be used for a given UV pulse of the second plurality of pulses (38), (ii) receive a plurality of detection signals from each of the IR detector (26) and the UV detector (36) and (iii) based on the detection signals, determine a concentration of at least one component of the sample gas.

Abstract: The spectrometer includes: a light source unit emitting a laser beam; a mirror unit including a first plane mirror having a first mirror surface and a second plane mirror having a second mirror surface, wherein a measurement target is introduced between the first mirror surface and the second mirror surface; and a light detector detecting the laser beam returned by multiple reflection between the first mirror surface and the second mirror surface. The first mirror surface and the second mirror surface are arranged non-parallel to each other when viewed from the Z-axis direction so as to form an optical path of the laser beam reciprocating in the Y-axis direction while performing multiple reflection between the first mirror surface and the second mirror surface. The optical path of the laser beam between the first mirror surface and the second mirror surface is inclined with respect to the Z-axis direction.

Abstract: A method and system for UV detection of sterilant concentration and dissipation in a volume of a chamber may comprise focusing cameras on at least one point of an object in the chamber; transmitting UV light and sterilant into the chamber; scanning, using the cameras, the at least one point of the object and determining an amount of absorbance at the points; calculating, using the amount of absorbance, a concentration of the sterilant for each of the one or more points; and when the concentration is greater than a threshold, removing the sterilant from the volume. The sterilant may be hydrogen peroxide. The cameras may be stereoscopic cameras. The chamber may be partitioned into a grid of voxels for scanning.

Abstract: Methods and systems for performing simultaneous spectroscopic measurements of semiconductor structures at ultraviolet, visible, and infrared wavelengths are presented herein. In another aspect, wavelength errors are reduced by orienting the direction of wavelength dispersion on the detector surface perpendicular to the projection of the plane of incidence onto the detector surface. In another aspect, a broad range of infrared wavelengths are detected by a detector that includes multiple photosensitive areas having different sensitivity characteristics. Collected light is linearly dispersed across the surface of the detector according to wavelength. Each different photosensitive area is arranged on the detector to sense a different range of incident wavelengths. In this manner, a broad range of infrared wavelengths are detected with high signal to noise ratio by a single detector. These features enable high throughput measurements of high aspect ratio structures with high throughput, precision, and accuracy.
