Publication number: 20120301872Abstract: The invention relates to systems and methods for improving optical detection and sensitivity in situations in which emission of luminescent light is monitored. It is provided a sample carrier which achieves increased sensitivity of luminescent light detection. The sample carrier comprises a sample carrying part and a light reflecting part; wherein the light reflecting part is positioned to allow an optical collection and detection system to collect not only luminescent light emitted from the sample positioned on the sample carrying part in a direction of the optical collection and detection system, but also luminescent light emitted from the sample in a direction away from the optical collection and detection system and reflected in the direction of the optical collection and detection system via the light reflecting part.Type: ApplicationFiled: November 17, 2010Publication date: November 29, 2012Applicant: GE HEALTHCARE BIO-SCIENCES ABInventor: Stig Tormod

Patent number: 6226084Abstract: The invention relates to a method of calibrating an optical system, the system comprising a flash lamp as a light source (4), a lens system (6), a monochromator comprising a grating (10), a motor (20) for displacing the grating so as to enable scanning essentially monochromatic light over a detection system. The light source provides at least two high intensity peaks at distinct wavelengths. The method comprises scanning a first wavelength region comprising at least one of said at least two high intensity peaks, and measuring the intensities at a selected number of points during the scan. A first of said at least two peaks is coarsely located. A wavelength region around each of said at least two peaks is scanned, measuring the intensities at closer intervals than previously. At least two peaks are located by autocorrelation. The location of said peaks is determined in terms of a distance from a reference point, said distance corresponding to said displacement of the grating.Type: GrantFiled: December 29, 1998Date of Patent: May 1, 2001Assignee: Amersham Pharmacia Biotech ABInventor: Stig Tormod
