Abstract: In a method for manufacturing a spectral module 1, a photodetecting unit 10 constructed by bonding a photodetector 5 and a light transmitting plate 56 together is attached to a front face 2a of a substrate 2 by an optical resin agent 63. Here, a light transmitting hole 50 of the photodetector 5 is covered with a light transmitting plate 56, whereby the optical resin agent 63 is prevented from intruding into the light transmitting hole 50. When preparing the photodetecting unit 10, a semiconductor substrate 91 provided with a photodetecting section 5a and the light transmitting plate 56 are bonded together, and then the semiconductor substrate 91 is formed with the light transmitting hole 50, whereby matters which may cause refraction, scattering, and the like to occur can reliably be prevented from intruding into the light transmitting hole 50.

Abstract: Method and apparatus for detecting, by absorption spectroscopy, an isotopic ratio of a sample, by passing first and second laser beams of different frequencies through the sample. Two IR absorption cells are used, a first containing a reference gas of known isotopic ratio and the second containing a sample of unknown isotopic ratio. An interlacer or reflective chopper may be used so that as the laser frequencies are scanned the absorption of the sample cell and the reference cell are detected alternately. This ensures that the apparatus is continuously calibrated and rejects the baseline noise when phase sensitive detection is used.

Abstract: An infrared spectrophotometer, which is capable of preventing measurement data measured from being adversely affected by moisture vapor. An internal space of an attachment receiving therein an optical element is sealed and isolated from ambient air by providing a tube and others, and a dehumidifier is provided in the internal space of the attachment for an optical path. Thus, the dehumidifier is disposed in a relatively narrow space, so that the internal space of the attachment can be efficiently dehumidified within a short period of time so as to reduce humidity in the internal space to suppress absorption of moisture vapor which would otherwise occur on the optical path in the internal space of the attachment. This makes it possible to prevent a negative influence of moisture vapor on measurement data, while reducing a standby time due to the dehumidification.

Abstract: The apparatus and methods herein provide quantitatively controllable light sources and expanded dynamic range endoscopy systems that can improve the quality of images and the ability of users to distinguish desired features when viewing tissues by providing methods and apparatus that improve the dynamic range of images from endoscopes, in particular for example with endoscopes that have dynamic range limited because of small image sensors and small pixel electron well capacity, and other optical system constraints. The apparatus and methods herein, for example, combine light sources with quantitatively variable spectral output and quantitatively variable wavelength dependent intensity distribution with image sensors and controllers to create an expanded dynamic range endoscopy system. By digitally combining illumination data from the digitally controllable light source with the digital image data from the image sensor the system synthesizes expanded dynamic range images whose dynamic range exceeds the dynamic range of the image sensor alone thus providing greatly enhanced information content in the acquired images.

Abstract: A toxic gas sensor or device (11) which is a cavity ring-down spectroscopy device having two or more mirror components (23, 24, 25). Each of the mirror components has two Brewster windows (17, 18) attached to it. The Brewster windows are resistant to toxic gases and together with a respective mirror (13, 14, 15) form a hermetically sealed volume (31) for the mirror surface to protect it from the environment (19) or test gases. The Brewster windows (17, 18) may have a heating mechanism (35) to remove contaminants, condensation, and provide temperature stabilization and other beneficial features.

Abstract: A hand-held, self-contained, battery-powered test instrument for analyzing composition of a sample includes an exciter for exciting at least a portion of the sample, a compact cross-dispersed spectrometer for receiving an optical signal from the excited portion of the sample and a processor for processing spectral data about the optical signal from the spectrometer. The exciter may include a spark generator and a counter electrode, a laser or other device for generating the optical signal from the sample portion. The spectrometer has a wavelength range broad enough to enable the test instrument to detect and determine relative quantities of carbon, phosphorous, sulfur, manganese, silicon, iron and other elements necessary to identify common alloys. The spectrometer includes a structural member made of a light-weight material having a small coefficient of thermal expansion (CTE). The spectrometer is dimensionally stable over a range of expected ambient temperatures, without controlling the temperature of the spectrometer.

Abstract: The invention relates to a device for measuring at least one gas component of a gas present in a measuring chamber. Said device comprises at least one radiation source which is adapted to the gas component which is to be detected in relation to the wave length range thereof, and at least one radiation detector which captures radiation emitted by the radiation source and transverses the gas present in the measuring chamber and converts it into electric signals. According to the invention, in order to modify the wave length emitted by the radiation source, the radiation source is applied to a miniaturised thermoelectric component, a miniaturised Peltier-cooler, whereby the electric supply thereof can be adjusted in a variable manner.

Abstract: A color measurement device designed for use at various stages of an industrial process is provided. The device offers enhanced insensitivity to ambient light, measurement depth variations, and/or ambient or environmental temperature variations. The device may be embodied as an LED-based, non-contact color measurement spectrophotometer. Over- illumination in full-spectrum of the target object facilitates effective color measurements over varying depths of view. Collected light is measured at discrete wavelengths across the entire visual spectrum. The hardened, rugged design and packaging of the measurement device allows color measurement to be performed at various stages of industrial processes wherein the device can add value by enabling enhanced detection of color errors.

Abstract: A spectroanalytical system for receiving radiation to be analyzed along a first path includes a grating in the first path with periodic faceted grooves for spatially separating the radiation as a function of wavelength. The blaze angles of the faceted grooves are progressively graded. A multielement detector detects radiation spatially separated by the grating. An optical conditioner is disposed in the first path between the grating and a multielement detector.
