The sample holder (60) is latched to the sample introduction hole (205) and holds the cell (C) for containing the sample, and the cell (C) is arranged such that the plane of incidence of the excitation light to the cell inclines against a plane perpendicular to the optical axis (L) of the excitation light.
Abstract:
A system for remotely detecting gas concentration is provided. The system includes a plurality of light sources. At least a first one of the light sources generates light having a first wavelength and a first polarization, and at least a second one of the light sources generates light having a second, different wavelength and a second polarization that is orthogonal to the first polarization. The light from the light sources is placed on a common transmission path, and is directed to a target area by a steering mirror. Light reflected from the target area is received and directed to a detector. The detector provides information regarding the time of arrival and amplitude of the received light, allowing range and gas concentration information to be obtained. In some embodiments the detector is an imaging detector, allowing three-dimensional range information to be obtained from the target area from a single light pulse.

Abstract:
Espectrofotómetro para caracterización de receptores (1, 2) de colectores solares para determinar propiedades ópticas (transmitancia y reflectancia). El equipo permite evaluar un tubo receptor en tiempo real y en cualquier condición lumínica, tanto en interior como en exterior. El equipo también permite detectar la excentricidad entre el tubo exterior e interior, lo que influye directamente sobre la fiabilidad de la medida. El equipo tiene un sistema mecánico para permitir un giro del equipo en torno al tubo para encontrar la posición óptima de medida y fijarse al tubo.
Abstract:
The invention is a fully enclosed sample analysis chamber with two halves which may be opened and closed to allow insertion of a sample and closing to keep out ambient light. The upper half has a downward-facing hemispherical dome, attached by hinges to the lower half which holds the planar analysis surface. The dome is provided with lighting means such as RGB LEDs disposed so as to provide uniform illumination of controllable color and intensity to the planar analysis surface when the device is closed. Image processing is carried out by camera under exactly reproducible conditions including use of automatic gain correction and area spectroscopy.
