  • Patent number: 9720218
    Abstract: A system for a laser-scanning microscope includes an optical element configured to transmit light in a first direction onto a first beam path and to reflect light in a second direction to a second beam path that is different from the first beam path; a reflector on the first beam path; and a lens including a variable focal length, the lens positioned on the first beam path. The lens and reflector are positioned relative to each other to cause light transmitted by the optical element to pass through the lens a plurality of times and in a different direction each time. In some implementations, the system also can include a feedback system that receives a signal that represents an amount of focusing of the lens, and changes the focal length of the lens based on the received signal.

  • Patent number: 9720222
    Abstract: This disclosure is directed to optical microscope calibration devices that can be used with optical microscopes to adjust the microscope imaging parameters so that images of samples can be obtained below the diffraction limit. The microscope calibration devices include at least one calibration target. Each calibration target includes a number of features with dimensions below the diffraction limit of a microscope objective. Separate color component diffraction limited images of one of the calibration targets are obtained for a particular magnification. The color component images can be combined and image processed to obtain a focused and non-distorted image of the calibration target. The parameters used to obtain the focused and non-distorted image of the calibration target can be used to obtain focused and non-distorted images of a sample for the same magnification by using the same parameters.

  • Patent number: 9720226
    Abstract: According to an instruction of opening or closing a block plate from a controller, a first solenoid valve and a second solenoid valve supply compressed air supplied from an air source to an air cylinder to operate a block in a uniaxial direction. The block plate is attached to the block, and the block plate operates similarly to the block in response to the operation of the block. In other words, by the opening or closing operation of the block plate, a state can be switched between a state in which a machining area can be seen through a viewing window, which is attached to a splash guard (or an opening/closing door) of the machine tool, and a state in which the machining area cannot be seen through the viewing window.
