Abstract: Focusing a generated radiation signal on a detector is effected by a curvilinear surface. The radiation beam signal from the reflected surface is collimated or focused on the detector. Light scattered, Raman scattered, fluorescence, chemiluminescence, phosphorescence radiation signals from particles as a result of a chemical procedure or reaction is enhanced through this focusing technique. The enhanced signal which is detected is subsequently measured through different detection techniques.

Abstract: A radiant energy detector comprising a silicon photovoltaic detector (24) and a lead sulfide photoconductive detector (22) in a common optical path and each responsive to radiant energy in different wavelength intervals. The silicon detector (24) also serves as a filter for isolating the wavelengths of radiant energy reaching the lead sulfide detector (22).

Abstract: Filtres biréfringents, accordables à bande modérément étroite, utilisant des cellules à cristaux liquides à torsion nulle en tant que retardeurs variables dans un filtre biréfringent de type Lyot. De tels filtres peuvent arriver à des niveaux de résolution et à des rapports diffusion-lumière analytiquement utiles pour des coûts compétitifs par rapport aux sources lumineuses monochromatiques à prisme et à réseau. Ces filtres biréfringents peuvent être accordés et/ou rendus opaques par l'application d'une tension adéquate aux cellules. Il est aussi possible de construire toute une variété d'instruments optiques différents sans parties mobiles. Les besoins en énergie sont négligeables. Un filtre utile peut être conçu pour occuper un volume inférieur à un pouce cubique. Grâce à ces propriétés, un tel filtre est idéal pour une régulation par microprocesseur.

Abstract: Moderately narrow band, tunable, birefringent filters using zero-twist liquid crystal cells as variable retarders in a Lyot-type birefringent filter. These filters can achieve analytically useful levels of resolution and stray-light ratios for costs that are competitive with prism and grating monochromators. These birefringent filters can be tuned and/or rendered opaque by the application of a suitable voltage to the cells. Thus, a variety of different optical instruments can be constructed with no moving parts. Power requirements are negligible. A useful filter can be designed to occupy a volume less than one cubic inch. These properties render such a filter ideally suited to microprocessor control.
