Abstract: A spectrometry instrument with exchangeable accessories (34, 48, 50, 52) providing, for example, different sample presentation facilities. The accessories include a manually operable cam-lock facility (54, 68) for quick and easy attachment of an accessory to the instrument. The instrument also includes an electrical circuit (86-90), which is completed by a circuit portion (100) in an accessory when the accessory is attached to the instrument, for generating a unique identifying voltage (94) to thereby identify that accessory. This allows for automatic loading in a controlling computer of programs for setting up and running the instrument for measurement regimes using that accessory. The spectrometry instrument is preferably a spectrophotometer used for phosphorescence decay measurements in which sequential phosphorescence emission measurements data from each of a number of excitation cycles applied to a sample are taken and then reassembled into a correct time sequence to define a phosphorescence decay characteristic for the sample, that is, measured data points from a second (and subsequent) excitation cycle are interleaved with those from a first excitation cycle. This significantly reduces the time for establishing a phosphorescence decay characteristic.

Abstract: In a spectrum measuring instrument of the present invention, a detecting surface (13a) of a detector (13) is a two-dimensional detecting surface and spectrum light coming out from a spectroscope is irradiated to a region A on the detecting surface (13a). Signal intensity at the regions on the detecting surface (13a) other than the region A where the spectrum light is irradiated is subtracted from signal intensity on the region A. Consequently, it is possible to obtain an accurate spectrum intensity signal by processing a detection signal in such a manner that adverse effects of stray light generated inside the spectrum measuring instrument and unwanted light generated by reflection and diffraction occurring on the surface of a detecting element are removed (FIG. 4).

Abstract: Single-mode and multi-mode fibers to achieve modal splitting and greater sensitivity in an optical fiber coupler for evanescent-wave biosensor applications. A source of light having multiple modes is coupled to the input to one of the multi-mode fibers, with the geometry of necked-down section being such that a limited number of modes may be carried by the multi-mode fiber as the light emerges from the coupler. At least one of the single-mode fibers is supported adjacent the multi-mode fiber to receive and carry one of the limited modes. A biomolecule enveloped by the evanescent field, exhibits a direct or indirect affinity to a binding partner, such that attachment of the binding partner is at least partially responsible for the limited number of modes carried by the multi-mode fiber as the light emerges from the coupler. A system-level implementation of the invention further includes instrumentation for receiving the light from the single-mode fiber carrying one of the limited modes, and determining a characteristic of the binding partner in accordance with the detected mode. The attachment of the binding partner may also causes a change in other detectable optical attributes, such as the magnitude or polarization of the light at one or both of the fiber outputs. The instrumentation may therefore further include a polarization-sensitive optical element supported at one or both of the outputs of the optical fibers, for example, in the form of a polarizing beamsplitter. One or more of the fibers may be pulled substantially without twisting so as to maintain polarization orientation, and the source of light may randomly, circularly, or linearly polarized.

Abstract: A spectrum analyzer providing an integrated calibration function and for providing that calibration function automatically. The injection of light to be analyzed through a central aperture of a scanning grating onto a focusing reflector provides in combination four traversals of the space therebetween. The spectrometer thus is used to separate wavelength information spacially and receive it back at the same or adjacent aperture(s) to be analyzed by a processing system to establish the spectra for the incident light. The light is typically injected from and received back into optical fibers or other light carrying elements. Calibration light is also applied through the same or adjacent apertures in the grating from a known source and spectra such as Argon to use as a calibration reference by detecting the known spectra peaks and correlating it to grating scan angle. The same structure is also used as a telecommunications channel router by injecting light of multi-channel and thus broadband spectral content into the spectrometer through the central aperture(s) and angling the grating so that a selected channel or channels are reflected back after four passages of the spectral separator to output one or more optical fibers or other guides.
