Abstract: A solar simulator produces synthetic spectral distribution characteristic with sufficiently high uniformity and repeatability and permits the intensity of output light to be varied without substantially deviating the spectral distribution of output light. The solar simulator includes filter means (13) capable of eliminating the near infrared component from the light of a xenon short arc lamp (11) and. extracting the near infrared component from the light of an incandescent filament lamp (12) enable the two kinds of lights which are selected by the filter means (13) to be directed coaxially to an integrating optical system (14).

Abstract: A kinematic lamp mount for mounting a spectral source lamp (3) such as a hollow cathode lamp accurately with respect to an optical axis of, for example an atomic absorption spectrophotometer comprises a base member (100), a lamp holder (1) and two spring means (120, 121) which urge the holer (1) into contact with the base member (100). The holder (1) is provided with three ball ended feet (6,8,10) two of which (6,8) are adjustable. Two feet (6 and 10) engage in an arcuate V-groove (102) while the third engages in a radial V-groove (103) giving kinematic connection between the holder (1) and base member (100). By providing kinematic connection between the holder (1) and base member (100) the lamp holder (1) and hence the lamp (3) may be removed from and later replaced sufficiently accurately on the base member (100) that no re-adjustment is necessary. A collection of lamps and adjusted holders may be kept and used consecutively without requiring intermediate adjustment once all the collection have been initially adjusted thus speeding multi-element analysis.

Abstract: A system for photometric measurement of optical properties of a fluid medium utilizing multi-wavelength excitation includes a movable diffraction grating that is continuously oscillated over the spectral range of interest and a flashlamp producing high intensity, short duration flashes. The angular position of the grating at the time of a flash determines what wavelength of optical energy will be passed to the remainder of the system. Because the flash duration is brief in relation to the period of movement of the grating, the flash effectively freezes the motion of the grating allowing the high intensity output of the flashlamp to be supplied to the fluid medium, while successive flashes permit measurement at many different wavelengths in near simultaneous fashion. The system is disclosed for use in an absorbance detector for liquid chromatography.

Abstract: An atomic absorption spectrophotometer includes a monochromator (MN) for passing radiation of a selected wavelength characteristic of an atomic element when that radiation is emitted by a source lamp (HCL1-HCL4) for producing resonance line radiation characteristic of one or more atomic elements. The souce lamp assemblies (HCL1-HCL4) are encoded to represent the element whose radiation they emit by means of resistor networks (RN1-RN4) which resistor networks are connected to a measuring circuit MCM. A microprocessor (µP) is conditioned to detect the lamp code and to select a set of information from a read only memory (ROM) to enable the wavelength of the monochromator (MN) to be set via wavelength control means (MWC), the bandwidth of the monochromator to be set via monochromator slit control (MSC) and the current to the lamp to be set via lamp supply unit (LPS).

Abstract: A radiation arrangement suitable for emitting IR radiation has a flat radiation source (2), the radiation emitted from which is deflected in at least one predetermined direction by a reflector (4); said reflector consists of a body, the circumference of which becomes smaller towards the beam outlet and the reflective surface of which is substantially surrounded by the radiation source; in an axisymmetrical arrangement, the distance between the radiation source and the axis of the reflected beam is greater than the radius of the reflector component arranged symmetrically in rotation along the optical axis. The radiation body may consist thereby of a resistive coating (2) on an electrically insulating substrate (3) or a self-supporting resistive strip or wire. An essential advantage here is that there is a relatively large area for the generation of IR radiation which can be bunched into a high-intensity beam by the reflector arrangement, as is necessary in measuring instruments, e.g. gas analysers.

Abstract: The method and apparatus of the present invention provides a system wherein light-emitting diodes (LEDs) (162) can be tuned within a given range by selecting their operating drive current in order to obtain a precise wavelength. The present invention further provides a manner in which to calibrate and utilize an LED probe (150), such that the shift in wavelength for a known change in drive current is a known quantity. In general, the principle of wavelength shift for current drive changes for LEDs is utilized in order to allow better calibration and added flexibility in the use of LED sensors, particularly in applications when the precise wavelength is needed in order to obtain accurate measurements. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past. Finally, the present invention provides a method and apparatus for determining the operating wavelength of a light-emitting element such as a light-emitting diode.

Abstract: Agencement de source de radiation infrarouge, notamment pour une utilisation dans l'analyse spectrale infrarouge. On applique à un substrat électriquement isolant (2) un et de préférence au moins deux films séparés électriquement conducteurs (2a, 2b) adaptés à être chauffés par l'application d'un courant électrique dépendant du temps. Deux ou plusieurs films peuvent former un groupe de radiations (réseau) dans lequel chaque film (2a, 2b) est adapté à être mis sous tension séparément avec un courant électrique provenant d'un circuit électrique d'attaque (1) et permettant d'appliquer au film ou films un courant électrique dépendant du temps, de préférence sous forme d'impulsion, de sorte que des impulsions de radiation infrarouge sont émises. Le courant électrique est commandé dans le temps afin de pouvoir distinguer l'une de l'autre dans un détecteur (6) les impulsions de radiation provenant des films respectifs. L'épaisseur du substrat et la conductivité thermique, la chaleur et la densité spécifiques du matériau de substrat sont choisies de manière à adapter la constante de temps thermique à la gamme de fréquence d'impulsion du circuit d'attaque.
