An optical device, such as a microscope, is disclosed that can be assembled from flat materials. The optical device can be assembled via a series of folds of a flat material. The optical microscope can include a stage for supporting a sample, an optic stage, and a light source. The optic stage can include one or more lenses. The optical microscope can be capable of obtaining simultaneous images from different forms of microscopy. The optical microscope may have bright field and filter field viewing capabilities wherein a user shifts from bright field to filter field by lateral movement of the stage containing a lens and a light source that cooperate to provide either the bright field or the filter field.

The invention provides a technology for promptly determining bacterial identification or an antimicrobial susceptibility testing. In the invention, first, a state where the bacteria are divided is monitored by performing microscopic observation with respect to the shape or the number of bacteria in each of wells of a culture plate for bacterial identification culture or the antimicrobial susceptibility testing. In addition, the shape, the number or the area of the bacteria are interpreted from the image obtained by the microscopic observation whether or not the bacteria proliferate at a stage from an induction phase to a logarithmic phase, and the time-dependent changes thereof are made into a graph. From the graph, it is determined whether or not the bacteria proliferate for each measurement, the determination results are displayed on the screen, and accordingly, the result of the antimicrobial susceptibility is provided every time when the measurement is performed (FIG. 12).

A sample observation device includes: an emission optical system that emits planar light to a sample on an XZ plane; a scanning unit that scans the sample in a Y-axis direction so as to pass through an emission surface of the planar light; an imaging optical system that has an observation axis inclined with respect to the emission surface and forms an image of observation light generated in the sample; an image acquisition unit that acquires a plurality of pieces of XZ image data corresponding to an optical image of the observation light; and an image generation unit 8 that generates XY image data based on the plurality of pieces of XZ image data. The image generation unit extracts an analysis region of the plurality of pieces of XZ image data acquired in the Y-axis direction, integrates brightness values of at least the analysis region in a Z-axis direction to generate X image data, and combines the X image data in the Y-axis direction to generate the XY image data.

A light source module for a microscope, including a light source configured to emit illumination light along an illumination light path, at least one light blocking shutter configured to be moved into and out of the illumination light path, and at least one light sensor configured to detect an intensity of the illumination light propagating along the illumination light path. The at least one light sensor is integrated with the at least one light blocking shutter to be moved therewith into and out of the illumination light path.

An optical microscope apparatus includes: a sample interrogation system configured to probe a sample location; and a light collection system configured to collect light output from a sample due to being probed by the sample interrogation system. The light collection system includes: a mirror positioned along an imaging axis that passes through the sample location; and an optical lens system including a plurality of optical lenses arranged along the imaging axis, at least one of the lenses being a multiplet optical lens.

The present invention relates to systems and methods for sequential operation of staining, imaging and sectioning of tissue samples by a processing system. After each layer of the sample is removed by the sectioning system, the system automatically stains the exposed surface of a sample to a depth to enable imaging of the remaining tissue. The system then repeats the sectioning, staining and imaging steps in sequence to image the sample.

An autofocus device includes a stage, a magnifying optical system, a light source device, an iris which is arranged at a position opposite to a sample of the magnifying optical system and configured to limit a light beam emitted from the light source device, and an AF camera which receives, via the magnifying optical system, a reflected light beam which is reflected from a reflection surface after the light beam reaches a glass member via the iris and the magnifying optical system. The light source device emits the light beam at a non-zero angle relative to the axis of the magnifying optical system. The control unit adjusts the position of the stage so as to match the position of a captured image of a shield with a target position. With such a configuration, it is possible to achieve the autofocus at high speed.
