Abstract:
Scanning of a microarray is performed through a mask that exposes a plurality, but not all, of the sites of the microarray, and either the mask is movable relative to the microarray or the microarray is movable relative to the mask, or both. The mask is useful as a means of restricting the illumination of sites on the microarray to those that can be illuminated while the scan head is traveling at a steady, target velocity, blocking the passage of light between the scan head and the microarray at those points in the scan head trajectory where the scan head is either accelerating or decelerating. The mask is also useful for reducing background noise in the microarray image by preventing light spillage to sites adjacent to those being scanned.
Abstract:
The invention relates to a system comprising a broadband optical light source and a sorting device and more specifically to laser sorting devices. The object of the present invention is to provide a system comprising a sorting device with a light-source offering all wavelengths for the sorting process. This is solved by using an all fiber supercontinuum light source.
Abstract:
PROBLEM TO BE SOLVED: To provide a device and a method capable of perfect optical inspection of point shaped, linear shaped or laminar defects at a plane surface area, wherein dimensions are in a submicron range. SOLUTION: This sensor comprises a telecentric laser scanner and a detection unit, and has a constitution wherein the telecentric laser scanner has a laser for approximately perpendicular lighting of a plane surface area, a scanning mirror, and a telecentric optical system for guiding lighting and detection beams, and the detection unit has a detection optical system, a central diaphragm arranged in the telecentric laser scanner direction concentrically near the detection optical system, a super sensitive photomultiplier for detecting scattered light emitted from a defect spot on the smooth surface, and a slit diaphragm connected to the front side of the photomultiplier.
