Abstract: A chemistry strip reader and method for analyzing chemistry strips. A conveyor moves chemical strips through different imaging positions at discrete points in time across the field of view of a camera, which captures images of each chemistry strip at different discrete times. A processor determines reflectance values for each of the chemical strips from the captured images at the discrete points in time. Calibration targets adjacent the chemistry strips can be used to adjust the determined reflectance values. The light source can sequentially illuminate each chemistry strip with three different wavelengths of light, where the processor calculates a concentration determination associated with the chemistry strip by calculating different chromaticity coordinates for the different wavelengths of light, and comparing them to known chromaticity coordinates for known analyte concentrations.

Abstract: A system and method of monitoring a laser output power and laser extinction ratio includes an optical subassembly physically placed between a point light source and a optical fiber device. The optical subassembly creates a convergent light beam by reflecting a collimated light beam from the point light source off an interior surface of a first side of the optical subassembly. The optical subassembly creates an incident ray of the convergent light beam by including on a second side of the optical subassembly a wedge-shaped air gap.

Abstract: A connector to an optical fiber comprises a prism, a ferrule and an aspheric lens. The prism includes a triangular wedge element having a first surface, a second surface and a base. The ferrule guides the optical fiber so as to contact the optical fiber with the first surface of the prism. The aspheric lens is integrated on the second surface, the integrated aspheric lens being positioned so that the prism serves to redirect a light beam at an angle relative to an axis of the optical source input through total internal reflection by utilizing the base of the triangle wedge element. The aspheric lens serves to collimate the redirected light beam or focus the light beam before being redirected. This arrangement may, for example, be used within a WDM system to multiplex and de-multiplex several wavelengths of light, using a “zig-zag” optical path configuration and thin film filters to separate the wavelengths.
