Sentence examples for setup an objective from inspiring English sources
In a conventional transmission-mode TERS setup, an objective lens is always utilized to focus the incident beam on the tip apex for excitation.
The confocal microscope setup with an objective (NA, 0.65) focuses the laser into a spot in a diameter of 2 μm and collects the luminescence effectively into a spectrograph, which enables a scanning of microregion to search single QD exciton spectral lines.
The dispersed beam propagates through the 4 f setup, which comprises a collimating lens and an objective lens (UPlanSApo 60X/ numerical aperture (NA) 1.2 W, Olympus, Japan).
Hence, the setup employs three objective lenses: one objective lens for illumination; a second one facing the first on the opposite side of the sample to provide feedback signal for the optimization; and a third one placed perpendicular to the other two in order to detect the fluorescence signal coming from the excited slice of a fluorescently labelled sample.
The spatial distribution of the power density was quite different in the two configurations: in the microscopic setup, the objective focused the laser beam on a small spot (0.6 to 0.8 µm) while in the fiber-optic configuration the distal end of the fiber was devoided of focusing optics providing an excitation area of ~20 µm.
As for the previous setup, the objective is to identify real-time dynamic changes provoked by the removal of different amounts of masses ranging from 12 to 3 kg on each test.
Maintain an objective tone.
