    Abstract: A measuring instrument with a parfocal combination of an ultra-violet to near-infrared (UV-NIR) spectrophotometer and a Fourier Transform Infrared (FTIR) spectrometer is disclosed. The parfocal configuration obviates lateral movement of the sample between two separate measurement instruments, and throughput is increased. The measuring instrument also includes an imaging apparatus, such as a camera or microscope ocular, to accurately position the measurement area of the sample. Beam directing elements, such as a mirror and objective lenses, are mounted on a common movable member. The common movable member, e.g. a linear or rotating turret, moves to properly align the desired beam directing element, thereby selecting the specific metrology mode. In addition, the measurement instrument includes a purging shroud along the FTIR spectrometer optical path.

    Abstract: In known spectrophometers, a single light source is used to illuminate both a sample and a reference. A single detector is used to detect the light at both the sample and the reference. A chopper wheel having aperture portions is used to allow the light to pass through a selected filter in the apertures. However, in such devices, the beams from the sample and the reference arrive at the detector at the same time and movable shutters need to be employed. Described herein is a spectrophotometer (10) comprising a single light source (12), a single detector (14), optics (30, 36, 340, 42, 44, 46, 48, 50, 52, 54, 56, 58, 90, 92, 100) for dually and alternatively reading a sample (94) and a reference (96), and which employs only one moving part. That moving part is a chopper (42) containing multiple pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f), each filled with a unique bandpass filter to select wavelengths to specifically illuminate the sample (94) or reference (96). To inform the spectrophotometer (10) whether and when it is reading the sample (94) or the reference (96), energy relay means (70a, 70b, 70c, 70d, 70e, 70f, 70g, 70h, 70i, 70j, 70k, 70l) are provided between an energy emitter (80) and an energy detector (82) in an amount of at least twice the number of the pass-through apertures (60a, 60b, 60c, 60d, 60e, 60f).

    Abstract: A micro-Raman device includes a first laser light source, a second laser light source, a first holder, a second holder, a first ND filter, and a second ND filter. The first laser light source and the second laser light source generate first laser light of a first wavelength and second laser light of a second wavelength, respectively. The second wavelength is different from the first wavelength. The first laser light and the second laser light proceed in a second direction orthogonal to a first direction while being separated from each other in the first direction. The first holder and the second holder are arranged overlapping each other in the second direction.
