Abstract: An example device includes a substrate having a first surface, an electrowetting force generation layer above the first surface, and a nanostructure layer formed above the electrowetting force generation layer, the nanostructure layer having nano-fingers formed thereon. The electrowetting force generation layer is to generate an electrical field to selectively move at least one reactant on the nano-fingers of the nanostructure layer.

Abstract: A method of calibrating a hyperspectral imaging device includes illuminating a hyperspectral imaging sensor with a light source having known spectral properties, sampling the light from the light source with the hyperspectral imaging sensor to obtain sampled spectral properties, and calibrating a performance characteristic of the hyperspectral imaging sensor based upon comparing the sampled spectral properties of the light source to the known spectral properties.

Abstract: The invention relates to an image generation device comprising a laser light source (1); a mirror assembly having two parabolic mirrors (3, 6) via which a scanning light beam (1a, 5) generated by the laser light source is directed onto a sample surface (9); a deflection device (2), in particular a micromirror scanner, which is controllable such that the scanning light beam (1a, 5) scans points of the sample surface in a targeted manner; and a detector (10) which detects radiation emanating from a scanned point of the sample surface. The spatial resolution of the image generation device is substantially defined by the narrowest possible focusing of the laser beam, and the accuracy of the adjustable deflection angle is defined by the micromirror scanner.

Abstract: Systems and methods for hyperspectral imaging are described. In one implementation, a hyperspectral imaging system includes a sample holder configured to hold a sample, an illumination system, and a detection system. The illumination system includes a light source configured to emit excitation light having one or more wavelengths and a diffractive element. The illumination system is configured to structure the excitation light into a predetermined two-dimensional pattern at a conjugate plane of a focal plane in the sample, spectrally disperse the structured excitation light in a first lateral direction, and illuminate the sample in an excitation pattern with the one or more wavelengths dispersed in the first lateral direction.

Abstract: An instrument for measuring characteristics of particles. A particle sample is introduced into a sample cell. The sample particles are subjected to gravitational or centrifugal forces wherein particle motion is dependent upon particle characteristics. The particles are illuminated by an illumination device to produce light scattered by the particles. The light is detected by at least one detector. Characteristics of the particles are determined from the detector signals.
