PURPOSE:To obtain an objective lens with small flare by composing a lens system of a convergent front group which includes a meniscus lens component having a convex surface on an object side and a convergent rear group which includes a positive lens having a large-curvature surface on the ...
MICROSCOPE OBJECTIVE LENS WITH LOW POWER 优质文献 相似文献Microscope objective lens A microscope objective lens, sequentially from an object-side, comprises a first lens group constructed of a positive lens element, a second lens group constructed of a negative lens element, and a third lens group...
PROBLEM TO BE SOLVED: To obtain an objective lens which eliminates the need of focusing at the time of performing photographing by switching the objective lens by setting so as to include the perfocal position of the objective lens attached at the microscope and having a different magnification ...
The estimated energy consumption per MAC as a function of the image block size\(N\)is shown in Fig.7. The energy required by the photonic image processor decreases rapidly with image block size. We also find that the majority of the power consumption is driven by the laser and\({P}_{...
A continuous- wave 980 nm laser diode with a power of ~5.5 mW was used to excite the plasmonic resonance for optical trapping (Fig. 2b). A ×40 microscope objective lens was used to focus this laser beam to the full-width at half-maximum (FWHM) of ~1.4 μm. The optical potential ...
The mouse was imaged on an upright optical microscope with the 980nm laser beam focused on the mouse brain. The objective lens was a scan lens (Thorlabs, 5×5×, work distance=25.1distance=25.1mm) or a water-immersion objective lens (Olympus, 20×20×, work distance=2.0distance=2.0...
On Chromatic aberration of magnetic lenses with a field distribution in the form of power low model [B(z) αz~n] The chromatic aberration of magnetic lenses with the field distribution in the form B(Z)伪Z~n, for all integer n, have been studied as objective and projec... ASA Alamir...

Two-color STExD imaging implemented with two low-power NIR CW lasers The versatile STExD mechanism described here allows applications in super-resolution fluorescence microscopy. A STExD microscope equipped with a 740-nm Gaussian excitation beam and a 1064-nm donut-shaped depletion beam was built ...
Lower-cost implementations have been reported in which the microscope objective is replaced by a camera lens from a mobile phone8, or a ball lens9, but their resolving power is limited by the small numerical aperture (NA) and high aberrations. Of these implementations, the use of mobile-...
