The present invention relates to a method for analyzing chromosomes through preparing a chromosome preparation, measuring at least one interference characteristic of the chromosome preparation and characterizing at least one chromosome structure by way of the interference characteristic. Also, the invention relates to the use of a near-field microscope for analyzing un-dyed chromosomes.

Marker-free chromosome screening

A method is disclosed for contactless determination of product characteristics, particularly in continuous or discontinuous fabrication of layer systems formed of a plurality of layers with different optical characteristics. The measuring apparatus and measurement methods for determining the characteristics of one of the respective layers are predetermined depending on the optical characteristics of this layer and depending on the optical characteristics of layers situated above it in the measuring direction. In a measuring device for this purpose, a plurality of detectors are provided for wavelength regions directly adjoining one another. The detectors and the signal processing device are constructed such that the light coming from the measurement surface with wavelengths of 200 nm to more than 2400 nm is evaluated in its entirety.

Method and arrangement for contactless determination of geometric and optical characteristics

A method and an apparatus determines a predicted corrosion resistance of deep-drawable iron sheets for body parts of motor vehicles. The method is caarried out with a measuring apparatus comprising one or more light sources with which the iron sheet is irradiated. The reflected light is concentrated by lenses, filtered through filters and the filtered light rays are imaged on a plurality of photoreceivers. The ratios of two respective filter wavelengths are evaluated by a computer from the signals thus obtained. From the values of the quotients of the filter wavelengths, predictions can then be made as to the paint migration values to be expected of the deep-drawable iron sheets painted in a later operation. A simple quality control of the iron sheets supplied by manufacturers for the production of components for motor vehicles can be based on these values.
