摘要:
An arrangement for direct input coupling of a laser, preferably of a short-pulse laser, for nonlinear sample excitation which is located outside of the microscope housing, into the beam path of a laser scanning microscope (LSM), comprising a housing in which is integrated an adjusting laser that can be coupled into the microscope beam path by beam splitters, wherein the housing is advantageously integrated so as to be insertable in the scan module of the LSMA, and a beam splitter for the direct coupling laser has high transmission in the direction of the objective and, further, partial transmission for back-reflections of the adjusting laser coming from the specimen for adjusting the overlapping of the adjusting laser and direct coupling laser.
摘要:
A beam corradiator for combining two radiation beams, preferably movable beams independent from each other in at least one direction, to scan and/or influence a sample, preferably a manipulation system and an imaging system, with a partially reflecting layer being provided for the corradiation, wherein the thickness of the layer is provided with a preferably consistent incline or decline over the optically effective cross-section of the beam corradiatior.
摘要:
Laser scanning microscope and its operating method in which at least two first and second scanning systems activated independently of each other and that can move in at least one direction illuminate a sample with the help of a beam-combining element, and the light is detected by the sample as it comes in, The scanning fields created by the light distributions on the sample mutually overlap to create a reference pattern on the sample with one of the light distributions, which is then captured and used to create the overlap using the second light distribution and/or a reference pattern arranged in the sample plane or in an intermediate image plane is captured by both scanning fields and used to create the overlap and/or structural characteristics of the sample are captured by the two scanning fields as reference pattern and used to create the overlap in which correction values are determined.

摘要:
Laser scanning microscope and its operating method in which at least two first and second light distributions activated independently of each other and that can move in at least one direction illuminate a sample with the help of a beam-combining element, and the light is detected by the sample as it comes in, characterized by the fact that the scanning fields created by the light distributions on the sample are made to overlap mutually such that a reference pattern is created on the sample with one of the light distributions, which is then captured and used to create the overlap with the help of the second light distribution (correction values are determined) and/or a reference pattern arranged in the sample plane or in an intermediate image plane is captured by both scanning fields and used to create the overlap (correction values are determined) and/or structural characteristics of the sample are captured by the two scanning fields as reference pattern and used to create the overlap in which correction values are determined.

摘要:
Process for the observation of at least one sample region with a light raster microscope by a relative movement between the illumination light and sample via first scanning means along at least one scanning axis essentially perpendicular to the illumination axis wherein at an angle to the plane of the relative movement, preferably perpendicular thereto, second scanning means are moved and an image acquisition takes place by the movement of the first and second scanning means being coupled and a three-dimensional sampling movement being done by the illumination of the sample wherein the second scamming means are coupled to the movement of the first scanning means in such a manner that straight and/or curved lines and/or plane and/or curved surfaces are scanned which are extended along at least one scanning direction of the first scanning means as well as along the scanning direction of the second scanning means.

摘要:
Process for observing at least one sample region with a light raster microscope by a relative movement between the illumination light and sample via a first scanner along at least one scanning axis essentially perpendicular to the illumination axis wherein several illuminated sample points lie on a line and are detected simultaneously with a spatially resolving detector. At an angle to the plane of the relative movement, a second scanner is moved and an image acquisition takes place by coupling the movement of the first and second scanners and a three-dimensional sampling movement being done by the illumination of the sample. The second scanner is coupled to the movement of the first scanner such that straight and/or curved lines and/or plane and/or curved surfaces are scanned which are extended along at least one scanning direction of the first scanner as well as along the scanning direction of the second scanner.
