Publication number: 20230244070Abstract: The present disclosure relates to a measuring system for measuring a light source in a polarization-independent manner, having a camera comprising a plurality of image sensors arranged in the form of a matrix, and a microscope optics, and to a method for measuring the light sources in a polarization-independent manner. The aim is to make it possible to measure the light output of the light source in an improved, simple and largely polarization-independent manner while maintaining the spatial resolution in the microscopic range. To that end, the present disclosure proposes that a linear polarizer is associated with each of the image sensors, wherein the linear polarizers are arranged in the form of a matrix in front of the image sensors and two or more, preferably four, polarizers form a matrix block, wherein the transmission directions of adjacent linear polarizers within a matrix block are rotated relative to one another, preferably by 45° or by 90°.Type: ApplicationFiled: June 16, 2021Publication date: August 3, 2023Applicant: Instrument Systems GmbHInventors: Frank MÜNCHOW, Stephanie GRABHER, Martin FINGER

Patent number: 10841507Abstract: An imaging system and method are provided in which a well of a microplate 050 is imaged by a camera 110 comprising magnification optics 112. The camera is controlled to acquire a series of images of the well with different exposures. The series of images comprise a base image with a base exposure and at least one further image with a larger exposure than the base exposure. The series of images are then merged into an output image which comprises in a center region of the well image content from the base image and at a peripheral region of the well image content from the at least one further image. Advantageously, the output image may allow for better assaying or analysis of the samples in the well than any of the individual images.Type: GrantFiled: June 22, 2018Date of Patent: November 17, 2020Assignee: TECAN TRADING AGInventors: Markus Schürf, Frank Münchow, Christian Oberdanner, Alexander Kaser

Patent number: 9778106Abstract: A spectrometer (1) comprises a light source (2), a monochromator (3) with at least one diffraction grating (4), a monochromator housing (5), an order sorting filter (7), a microplate receptacle (12) and a controller (6). The order sorting filter (7) of the spectrometer (1) comprises a substrate (23), a first optical thin film (24) and a second optical thin film (25), wherein, in a spatially partly overlapping and interference-free manner, the first optical thin film (24) is arranged on a first surface (26) and the second optical thin film (25) is arranged on a second surface (27) of the substrate (23). A spectrometer (1) equipped with a respective order sorting filter is used in a scanning method for detecting the absorption spectrum of samples examined in wells (14) of microplates (13).Type: GrantFiled: July 8, 2015Date of Patent: October 3, 2017Assignee: TECAN TRADING AGInventors: Lutz Niggl, Andreas Erlbacher, Frank Münchow
