Sentence examples for object lens from inspiring English sources

By putting a prism in front of the object lens of a telescope, his team was able to photograph the spectra of many stars at once.

Images were acquired using the 10x/0.4 HC PLAPO CS object lens and the 40x/0.85 HCX PLAPO CS object lens.

Corrected the astigmatism of the object lens at a magnification of 600 k.  .

Linear ulcer and stenosis were observed Fig. 6 Histopathological analysis showing inflammatory cell invasion through all layers of the intestine (a; hematoxylin and eosin stain ×5) and epithelioid granulomas (b; hematoxylin and eosin stain, object lens ×40).

As a simple estimation, the distance from the electron object lens to the writing field center is 8 mm, whereas that from the lens to the writing field corner is (82 + 0.52 + 0.52 1/2 = 8.031 mm or 31 μm farther than to the writing field center, which is in the same order as our optimal defocus value.

Several specimens punched from the cross sections of the products were electrochemically thinned in an electrolyte of nine parts of methanol and one part of perchloric acid with twin-jet electropolish at −30 °C and were examined using a JEM-1200EX transmission electron microscope (TEM) with a magnetically shielded object lens pole-piece operated at 120 kV.

The 63x/1.2 HCX PLAPO CS and 40x 1.25-0.70 HCX PL APO CS object lenses were used to obtain images when fluorescent proteins were targeted to any location.

For the histological evaluation, a Zeiss Axioskop light microscope with 6 object lenses of magnification of 2×, 4×, 10×, 20×, 40× and 100× and LED light source was used.

The relative aperture for a microscope is called the numerical aperture (NA) and is equal to the sine of half the angle subtended by the aperture at an object point times the index of refraction of the medium between the object and the objective lens.

The benefits of this hybrid design include the fact that such an aperture allows one to obtain high-contrast images of weak-phase objects with the objective lens set to Scherzer defocus.

If the focal length of the objective lens is 10 centimeters and the focal length of the eyepiece lens is 5 centimeters, the magnification is simply 10/5 = 2. Find the distance between the lenses and the object.
