Method for imaging regions of a sample using a light source and an optical detection means and at least one device for moving the sample in three dimensions, comprising the following method steps: a) introducing at least one magnetic element into the sample, b) applying a magnetic field by means of the at least one device for moving the sample in three dimensions, the magnetic field interacting with the at least one magnetic element introduced into the sample, c) arranging the region of the sample in a radiation region of the light source and in a detection region of the detection means, d) emitting first light beams from the light source onto the sample, e) generating second light beams by means of the sample, f) recording an image of a region of the sample by capturing a proportion, incident on the detection means from the sample, of the second light beams, g) moving the at least one magnetic element and the sample containing this at least one magnetic element by varying the magnetic field, h) repeating steps d) to g) until a predeterminable number of images have been recorded.
摘要:
The present invention provides a substrate collecting device (1) that includes a stage (3) on which a sheet (11) is placed with a plurality of substrates (2) facing downward, an acquiring section (4) which carries out a predetermined operation on some of the substrates (2), which are disposed at predetermined positions, from above the stage (3) thereby to cause the substrates (2) to come off from the sheet (11) and fall, an observation section (5) and a collecting section (7) disposed below the stage (3), and a moving mechanism (8), which integrally moves the observation section (5) and the collecting section (7) in a horizontal direction. The moving mechanism (8) is capable of positioning the observation section (5) and the collecting section (7) at two positions at which the observation section (5) or the collecting section (7) is positioned substantially vertically below a predetermined position.
摘要:
A microscope system includes a casing in which an optical element is housed, an airtight specimen chamber, and an environment control unit that controls temperature and humidity in the specimen chamber and also controls temperature inside the casing. An upper plate of the specimen chamber is an open/close lid opened and closed when inserting or removing a biological specimen. The casing becomes sealed by a bottomplate of the specimen chamber as the specimen chamber is set on the casing.
摘要:
Die Vorrichtung zur Übertragung von Schnittbändern auf Probenhalter für die Transmissions- Elektronenmikroskopie (TEM) weist zwei voneinander unabhängige Werkzeuge (4) und (17) einerseits für die Manipulation der Schnittbänder und andererseits für die Manipulation der Probenhalter (grids) auf, welche während des Schneidvorganges selbständig durch zwei voneinander unabhängige Mikromanipulatoren (3) und (10) positionierbar sind. Das Werkzeug (4) zur Manipulation der Schnittbänder (24) umfasst ein Metrallrohr (13), ein Rohr aus einem elektrisch isolierenden Werkstoff (14) sowie eine auswechselbare Spitze (5). In dieser Spitze (5) ist eine mit einer elektrisch leitenden Oberflächenschicht versehene elastische Faser (16) aus dielektrischem Material auswechselbar eingesetzt, welche zur schonenden Handhabung der Schnittbänder verwendet wird.

The invention relates to a micromanipulator arrangement comprising at least one drive stem (120, 821), at least one movable element (130, 320, 360) arranged on the drive stem (120, 821) to move along the drive stem (120, 821 ) wherein the drive stem (120, 821) being arranged to cause a change in a position of the movable element (130, 320, 360) with respect to the drive stem (120, 821); wherein an additional factor exists having an effect in the change of the position of the movable element and the micromanipulator arrangement further comprises means (870) for compensating said additional factor such that said effect is diminished.
摘要:
A super resolution optofluidic microscope device comprises a body defining a fluid channel having a longitudinal axis and includes a surface layer proximal the fluid channel. The surface layer has a two-dimensional light detector array configured to receive light passing through the fluid channel and sample a sequence of subpixel shifted projection frames as an object moves through the fluid channel. The super resolution optofluidic microscope device further comprises a processor in electronic communication with the two-dimensional light detector array. The processor is configured to generate a high resolution image of the object using a super resolution algorithm, and based on the sequence of subpixel shifted projection frames and a motion vector of the object.

The device for producing laser-cooled atoms comprises a two dimensional trap or a three-dimensional trap, or a combination of two- and three-dimensional traps. The two-dimensional trap comprises: three or more permanent magnets arranged around a perimeter of a loop, wherein a plane of the loop is perpendicular to a free axis of the two-dimensional atom trap, and the three or more permanent magnets bracket an internal volume of the two-dimensional atom trap; and one or more laser beam input ports enabling access for one or more laser beams to the internal volume of the two-dimensional atom trap.
