Abstract: An apparatus for optically detecting light-absorbing contamination in at least one particle of low optical-loss material comprises an optical integrating chamber for containing the particles. A laser for emitting a laser beam to illuminate the particles is mounted in the plane of rotation of a rotating mirror such that the laser beam scans in a fan scan. A scanning assembly is mounted in optical alignment with the laser for reflecting the laser beam and for causing the laser beam to scan the particles in the optical integrating chamber. A focusing assembly is mounted in optical alignment with the laser for focusing the scanning laser beam onto the particles in the chamber, the focusing assembly operating in conjunction with the scanning assembly so that light from the laser beam is reflected from the particles and is repeatedly scattered onto the interior walls of the integrating chamber. A light sensing assembly is mounted on the integrating chamber for receiving the repeatedly scattered light from the interior walls of the integrating chamber and for generating a signal indicative of the intensity of the repeatedly scattered light. A decrease in the intensity of the repeatedly scattered light is a function of the presence of light-absorbing contamination in the material.

Abstract: A converter for using a spectrophotometer as a fluorometer includes a barrier for blocking the light in a collimated beam from reaching the detector of the spectrophotometer after this light has passed through and excited a sample material. A second detector is positioned to receive any fluorscence from the material which is emitted in a direction substantially perpendicular to the path of the collimated beam. A signal, generated by the second detector in response to fluorescence from the sample material, is modified to drive a second light source with an intensity which is linearlized relative to the generated signal. The detector of the spectrophotometer then receives the output from this second light source to measure the intensity of the fluorescence.

Abstract: Apparatus for determining the effective surface roughness of polished optical samples, by measuring the total integrated scattering, only operates for non-light-transmissive samples. For a transmissive sample, the invention adds a light trap behind the sample for transmitted light, and a diaphragm in front of the sample. The rear surface of the diaphragm is provided with a non-reflective wafing which traps secondary light reflected or scattered by the inside rear surface of the sample.

Abstract: Biosensor including a device base having a sensor array of light sensors and a guide array of light guides. The light guides have input regions that are configured to receive excitation light and light emissions generated by biological or chemical substances. The light guides extend into the device base toward corresponding light sensors and have a filter material. The device base includes device circuitry electrically coupled to the light sensors and configured to transmit data signals. A passivation layer extends over the device base and forms an array of reaction recesses above the light guides. The biosensor also includes peripheral crosstalk shields that at least partially surround corresponding light guides of the guide array to reduce optical crosstalk between adjacent light sensors.
