Abstract: A light microscope having a scanner for scanning a sample with illuminating light and a light detector for measuring sample light. A microlens array having a plurality of microlenses is arranged in front of the light detector in the region of a pupil plane. The light detector respectively has a plurality of detector elements behind each microlens and has a complete readout frequency of at least 100 kHz. By means of the detector elements arranged behind the respective microlens, a wavefront datum regarding the sample light is determined. Moreover, a sample point signal is computed from signals of the detector elements. Illuminating light is successively deflected onto different sample points with the scanner and corresponding sample point signals are captured, wherein, for at least some of the different sample points, a corresponding wavefront datum is also determined. The determined wavefront data can be taken into account in a calculation of a sample image from the plurality of sample point signals.

Abstract: A confocal microscope includes a housing, which may be printed, and which includes mounts for receiving optical and other components of the microscope.

Abstract: Atomic layer deposition methods for coating an optical substrate with magnesium fluoride. The methods include two primary processes. The first process includes the formation of a magnesium oxide layer over a surface of a substrate. The second process includes converting the magnesium oxide layer to a magnesium fluoride layer. These two primary processes may be repeated a plurality of times to create multiple magnesium fluoride layers that make up a magnesium fluoride film. The magnesium fluoride film may serve as an antireflective coating layer for an optical substrate, such as an optical lens.

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: The described method and system allow the simultaneous detection of multicolored samples, e.g. in live cells or tissues, in a simple experimental geometry. It relies on combining ultrashort ultra-broadband laser sources (10) with a fluorescence microscope setup able to collect fluorescence intensities and/or photon arrival times per excitation volume, as well as nonlinear signals, such as second/third-harmonic and sum-frequency generation. In the description, the presented method is referred to as “SyncRGB method”.

Abstract: A liquid lens can tilt a fluid interface, such as for optical image stabilization or off-axis focus. Tilting the interface can cause coma aberration or other dynamic wavefront error. The liquid lens can be driven to reduce the coma aberration or other dynamic wavefront error. For example, input shaped signals can be used. In some cases, the signals can be overdriven and/or underdriven, which can increase response time, and/or encourage settling of the interface.
