Abstract:
An optical head (41) comprises first and second members (51, 61) and a tubular member (71). First to fifth holes (52-56) are so formed continuously in the first member (51) as to extend therethrough. Sixth to eighth holes (62-64) are so formed continuously in the second member (61) as to extend therethrough. The second member (61) is inserted into the fifth hole (56) and secured. A semiconductor light- emitting device (23) is inserted into the sixth hole (62). The tubular member (71) has first and second tubular portions (72, 73) and is inserted in the fourth hole (55). A lens (27) is secured between a step portion formed in the border between the second and third holes (53, 54) and the first tubular portion (72). A beam-shaping member (25) is secured between a step portion formed in the border between the fourth and fifth holes (55, 56) and the second member (61).
Abstract:
Es wird eine Vorrichtung (1) zur Spektroskopie einer Probe (3) in abgeschwächter Totalreflexion vorgeschlagen, die ein Reflexionselement (2) mit einer ersten der Probe (3) zugewandten und einer zweiten der Probe (3) abgewandten Seitenfläche (21, 22) umfasst, wobei die erste Seitenfläche (21) zur Führung eines für die Spektroskopie der Probe (3) vorgesehenen Lichtstrahls (101) über innere Totalreflexion vorgesehen ist. Erfindungsgemäß weist die zweite Seitenfläche (22) eine Mehrzahl von zueinander beabstandeten beschichteten Reflexionsbereichen (42) auf, die zur Reflexion des Lichtstrahls (101) ausgebildet sind.
Abstract:
A ballast water monitoring device and a method for detecting live phytoplankton are disclosed. The device comprises a chamber for receiving a sample, at least one light source to emit light towards the sample, a light detector to receive light from the sample and generate a light signal, and a controller. The controller is configured to control the at least one light source to emit a single pulse of light, calculate the variable fluorescence [Fv] of the sample in response to the pulse of light, at time intervals less than the duration of the pulse of light, compare the calculated variable fluorescence to a predetermined reference limit, and perform an action if the calculated variable fluorescence is greater than the predetermined reference limit.
Abstract:
Various embodiments of a light detection device (110) and a method of using such device (110) are disclosed. In one or more embodiments, the light detection device (110) includes a housing (112) including a top surface (114) and a bottom surface (116), where the housing (112) extends along a housing axis (104) between the top surface (114) and the bottom surface (116); and a support member (160) connected to the housing (112) and adapted to be selectively moved from a closed position to an open position. The support member (160) is further adapted to maintain the light detection device (110) in an upright position when the bottom surface (116) and the support member (160) are in contact with a working surface (102) and the support member (160) is in the open position.
