A method for determining the color perception of multi-layer dispersive materials or biological materials for layer thicknesses that are respectively selective, by the determination of the diffuse reflectance based on the respective intrinsic optical parameter using Monte Carlo simulations and taking into consideration the measurement geometries, anisotropy and the dispersion phase function in order to correctly take into account the multiple internal dispersion of the material. The color effect is calculated from the diffuse reflectance based on the various color systems in accordance with different algorithms.

The aim of the invention is to investigate the bonding of substances to target molecules. This is achieved by means of a densely packed device wherein various target molecules are bonded in a large number of sample areas. Cross-contamination and evaporation need to be minimized. The active surface of the sample areas have to be maximized. The inventive solution resides in the use of carrier plates, containing densely packed capillary structures and having a very large inner surface despite small outer dimensions. 1000 times more molecules can be bonded than on a flat outer surface of a comparable size. Cross contamination is avoided by the lack of cross links between the capillaries. Evaporation is minimized by a small outer surface. After the inner surface of the capillaries has been silanized, peptides and peptidomimetics are synthesized in a locally targeted manner. The molecular interactions of components of the substance library with active substances in a solution or a suspension are investigated by means of a local resolution optical detection method. Handling, especially cleaning and covering with substances, is carried out in a simple manner by rinsing liquids through the capillary plate.

A microscope is disclosed in which a specimen is arranged between two objectives and can be observed with reflected light as well as with transmitted light. In a microscope with field transmission, two objectives have substantially identical optical characteristics and at least one of the two objectives is followed by a mirror which reflects the light transmitted through the specimen back into itself exactly. In this way, there is twofold transmission through the specimen with optimum illumination of the solid angle. In a laser scanning microscope, there are likewise two objectives with identical optical characteristics and at least one of the objectives is followed by a phase-conjugating or adaptive mirror.

A large number of cells can be evaluated in terms of their reaction state with molecular reactants under near-field optical conditions in a measuring and evaluation procedure of the invention. Light sources of different aperture diameters in the nano- or micro-range are disposed in a sample platform. The 2D-nano-light source array is embodied by a plurality of near-field light sources which are arranged in mutually juxtaposed relationship in raster form and are excited jointly or in succession. The carrier material used is a semiconductor material.

A process to remove a surface layer from a substrate by irradiating laser radiation, wherein the surface is scanned sequentially with the laser radiation being concentrated to a focus, before irradiating a predetermined surface element a thin fluid film or a fluid droplet cover is applied which covers at least that surface element, and the laser beam influences the surface element only for a very short treatment interval, especially less then 10 ms. By appropriate choice of the process parameters power density, treatment interval length, thickness of the fluid film, surface adhesion of the fluid, absorption characteristics of the fluid for the effective laser wavelength, and absorption characteristics of the fluid vapor an explosive evaporation of the fluid film is effected which results in a flaking of the surface and an evaporation of loose residues of the surface layer.

A method and apparatus for the ablation of hard biological material, such hard dental material, using a rapidly pulsed laser employ a crystal or absorber film disposed in the propagation path of the laser radiation, the crystal or absorber film being disposed at the laser output and serving as an interface with an optical conductor which conveys the laser radiation to the treatment site. The crystal or absorber film smooths the time/intensity characteristics of the pulsed laser radiation to the extent that transmission to the treatment site using optical wave guides is possible. Additional protective features are provided to prevent the ablated biological material to destroy the exposed optical end surfaces of the treatment applicator. Additional design features improve the ergonomic efficiency of the handpiece and its ability to be sterilized.

The invention is directed to a device for removing water from the solvent recovery system of a fast printer. Water recovered in the solvent recovery system from solvent vapor and water vapor is passed into the open air outside of the printer frame without generating damage due to water corrosion within the printer. Recovered water is passed from a discharge pipe to an evaporation chamber containing either a heated evaporator container or to a unheated trough containing upstanding absorbent mats which suck the recovered water up into an open air space above the trough. A stream of dry warm air is generated by blowers within the printer and passes through the evaporation chamber picking up water vapor. The vapor-air mixture produced in the evaporation chamber then passes through slots formed in the printer assembly frame directly into the open air.
