Sentence examples for using an objective lens from inspiring English sources

As shown in Figure 1, an object image is usually magnified by using an objective lens in the DHM system, and the enlarged object beam is reflected from front and back surfaces of an optical window glass.

The rigid endoscope was positioned orthogonally to the sample plane at a distance of 2cm and the sample plane was imaged onto a CCD Retiga-2000RR, QInc.ing, InCanadanada) using an objective lens (SM1NR05, Thorlabs, Inc., US).

In transmission mode (Fig. 3a), a laser beam is focused onto the sample through a transparent substrate using an objective lens with high numerical aperture (NA), which is usually >1.0 [29].
