Abstract:
An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.
Abstract:
An apparatus adapted for confocal imaging of a non-flat specimen comprising a coherent light source for producing a light beam, imaging optics adapted to focus the light beam into at least one spot on a surface of a specimen, and a detector adapted to receive and detect light reflected from the specimen surface. The imaging optics comprise at least one optical component located so that the light reflected from the specimen surface passes therethrough on its way to the detector. The optical component is movable so as to move the at least one spot, within a range of movement, to a number of distinct locations in a plane perpendicular to the apparatus' optical axis, within the detector's integration time.
Abstract:
This disclosure provides systems, methods and apparatus for measuring the direction distribution of light. In some implementations, an ambient light direction distribution sensor device can include, for example, a light steering layer that is designed to steer light from different incident angles toward associated locations on a light detector. The light detector can then output one or more signals that are indicative of the amount of light that is incident upon the sensor device from different incident angles. These measurements can be used to control various parameters of a display in response to the detected ambient lighting conditions.
Abstract:
According to an embodiment, a measuring device for measuring a laser beam comprises a magnification lens system with a total of two lenses which are arranged in series in the beam path of the laser beam and whose foci are coinciding, as well as a camera which is arranged behind the two lenses in the focus of the last lens and includes an electronic image sensor which generates an electronic image of the magnified laser beam. The lenses together with the camera are adjustable along the beam path relative to a reference point of the measuring device, for the purpose of locating the beam waist of the laser beam and of determining a diameter profile of the laser beam. The measuring device further comprises an adapter enclosing the beam path for coupling the measuring device to a laser system which provides the laser beam. The adapter forms an abutment surface or the laser system, which is axially directed with respect to a beam axis of the laser beam, and permits the measuring device to be coupled in situ at the installation site of the laser system.

In certain embodiments, a detection device includes a structure having an entrance that permits radiation to enter the structure and a radiation detector operable to detect radiation that enters the structure. The device also includes a microshutter array coupled to the structure and aligned with the entrance, the array comprising a plurality of microshutter cells operable to move between a first position in which that microshutter cell prevents radiation of a first wavelength from passing through a portion of the entrance and a second position in which that microshutter cell permits the radiation of the first wavelength to pass through the portion of the entrance. The device further includes an actuating device operable to define a first entrance pupil having a first f-number by moving a plurality of microshutter cells associated with the first f-number.
Abstract:
A high-speed optical measurement apparatus includes an objective lens unit, an optical path unit, a control circuit unit, a measurement sensor, an eyepiece unit, and a measurement sensor connection. The objective lens unit adjusts the magnitude of the overall light of the individual locations of the object or the set of multiple objects, and allows the light to make its entrance. The optical path unit changes the path of the incident light. The control circuit unit outputs a control signal which is used to change a direction of the light by controlling the optical path unit. The measurement sensor measures the incident light. The eyepiece unit conforms the light to the size and location of the measurement sensor. The measurement sensor connection fastens the measurement sensor so that the light incoming through the eyepiece unit is aligned with the measurement sensor.
