Abstract: The invention relates to a microscopy method for identifying target objects (32) having a predetermined optical property in material (6) to be analyzed.

Abstract: The invention is based on a microscope, in particular a fluorescence analysis microscope, comprising an illumination carrier and illumination units arranged thereon for a reflected-light illumination of a sample region. In order to be able to illuminate a sample region uniformly in a simple manner by means of a compact device, it is proposed that at least three illumination units for the simultaneous reflected-light illumination of the sample region from different directions are arranged on the illumination carrier.

Abstract: The invention is based on a microscope (2), in particular a fluorescence analysis microscope, comprising an illumination carrier (20) and illumination units (22a, 22b) arranged thereon for a reflected-light illumination of a sample region (10). In order to be able to illuminate a sample region (10) uniformly in a simple manner by means of a compact device, it is proposed that at least three illumination units (22a, 22b) for the simultaneous reflected-light illumination of the sample region (10) from different directions are arranged on the illumination carrier (20).

Abstract: The invention relates to a method for recording a characteristic of at least one object (28, 56, 68). According to the invention, a) a luminous radiation that is influenced by the object (28, 56, 68) is fed to an image sensor (6), b) at least two different partial images (32, 34, 36, 48, 78, 90, 94, T1, T2) consisting of pixels (26) are read out in succession from the image sensor (A11, A12, A13, A21) and values assigned to the pixels (26) are fed to an evaluation unit (10), c) the respective characteristic (B11, B12, B13, B21) of the object is determined from the values that are assigned to a partial image (32, 34, 36, 48, 78, 90, 94, T1, T2), d) the partial images (32, 34, 36, 48, 78, 90, 94, T1, T2) are combined to form a total image (38), which is output for further processing.

Abstract: The invention relates to a process for the production of a clamping means for clamping a component (20) in a holder (16), especially for the production of moulding tools for the manufacture of precision articles. Spring-action clamping elements (72), for example tightening discs or clamping sleeves (72), are inserted into a recess of the holder (16) and final working thereof takes place in a position that corresponds to the subsequent position when the component (20) to be clamped is clamped. With this process, very good centricity and coaxiality of the clamped components (20) is achieved, whereby the manufacturing tolerances to be maintained for the individual components are not critical.

Abstract: In an inspection module for inspecting optical parts (12) for defects, especially contact lenses manufactured as injection-moulded parts, the optical parts (12) are illuminated from one side and are observed from the opposite side by means of an image-resolving sensor (34). The image data of the sensor (34) are forwarded to image-processing means for identification of defects. To obtain a high throughput with a simple construction, a chain (52) of liquid-filled vessels (10) circulating in an endless line is provided. The endless line is passed in an inspection station (72) between an illumination device (32) and the image-resolving sensor (34). Handling means in the form of grippers (56, 58) revolve with the vessels (10), by means of which optical parts (12) to be inspected can be introduced into the vessels (10) at a position of the line upstream of the inspection station (72) and the inspected parts can be taken out of the vessels (10) at another position of the line.

Abstract: The invention relates to an apparatus for the photo-initiated chemical cross-linking of material (28). To form one or more mouldings the material is enclosed in an optically transparent mould (26). The apparatus has at least one light source (12), for example a pulsed UV light source by which the material (28) can be acted upon by a light that triggers the cross-linking. The region to be cross-linked in the mould (26) is determined at least partially by beam-delimiting elements (20, 22) between the light source (12) and the mould (26). That can be achieved by arranging between the light source (12) and the mould (26) a mask (20) having transparent and non-transparent surface portions. The mask (20) is then projected onto the material (28) that is enclosed in the mould (26) by projection optics (24). The projection of the mask (20) onto the material is effected in a telecentric beam path.
