  • Patent number: 10935778
    Abstract: A confocal microscope for imaging tissue having an imaging head for capturing optically formed microscopic sectional images of tissue samples, a platform upon which is disposed a linear stage for moving the imaging head along a vertical dimension, and a rotary stage to rotate the linear stage and imaging head about the vertical dimension. A mounting arm couples the imaging head to the linear stage to adjust tilt of the imaging head and to rotate the imaging head about a normal axis perpendicular to an optical axis of an objective lens of the imaging head. In a first mode of operation, the imaging head is positioned to image an ex-vivo or in-vivo tissue sample upon the platform, such as ex-vivo tissue sample mounted upon a movable specimen stage, and in a second mode of operation the imaging head is positioned to image an in-vivo tissue sample beside the platform.

  • Patent number: 10921572
    Abstract: A method for phase-contrast microscopy on a specimen, and the microscope and optical unit for carrying out the method, is provided. The specimen is arranged in a vessel having an object liquid, in which a component of an illumination beam, which serves as direct radiation and has not been diffracted by the sample, is applied to a phase-shifting element, is characterized in that the illumination beam is deflected before it enters the object liquid by way of an optical deflection element which is changeable in terms of position and/or shape so as to compensate for a change in the main radiation direction of the illumination beam that occurs due to optical refraction at the object liquid.

  • Patent number: 10921553
    Abstract: Systems and methods of the present disclosure are directed to optics used in absorption cell spectrometers. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. In some implementations, the orientation of the mirrors are aligned with specific orientations to provide the desired optical path to the detection light. In one or more embodiments, an alignment apparatus can be used to pre-align the mirrors before they are placed within the absorption cell. The alignment apparatus includes an aperture plate and an adjustable mount to mount one or more mirrors. The mirrors are aligned based on reflected images on the aperture plate laser light incident on the mirrors.

  • Patent number: 10884227
    Abstract: Light Sheet Theta (LS-?) Microscopy achieves large sample imaging capabilities without affecting the imaging depth or the image quality. An optical layout places a detection objective normal to the sample surface, while placing the illumination objectives that generate light sheets at an angle (theta) significantly smaller than 90 degrees. In this configuration, the light sheets enter from same side of the sample as the detection objective. The intersection of the light-sheet and the detection focal plane results in a line illumination-detection profile that is discriminated by a camera.
