A Potential Application of Photonic Jet in Observing Micro-Metric Materials

Abstract

Photonic jet microscopy is a technical field of microscopy applying photonic jet phenomenon to increase the resolution of objects or area of objects being observed. Mostly it is used in optical microscopy as the demand of visual observations are increased, especially for the micro-metric biological objects. In addition to our previous works inoptical assessment of observing a micrometric object under a microsphere using an optical microscope, now we made the electromagnetic assessment. It concludes if smaller microsphere magnifies greater than bigger microsphere. Therefore, applying photonic jet microscopy for visual observation is getting closer.

The Operational Mode of Optical Microscope Applying Photonic Jet Microscopy

“…Even though soda-lime glass microspheres do not yield image magnification as large as barium titanate does, they also have a smaller numerical aperture than barium titanate¬'s, making barium titanate microsphere can visualize finer details than soda-lime microsphere with a smaller numerical aperture. Our calculations using soda-lime glass (FIGURE 4) emphasize our previous publications [5,6] and experiment results in the laboratory, also other's [11]; that is worth to mention: soda-lime glass microsphere yield the largest image magnification using the diameter of 25 µm.…”

“…In laboratory practices, the operational mode of these optical microscopes applying photonic jet is either by putting the microspheres and the object in free space or in immersed liquid [3,4]. We have demonstrated the operational mode in free space by lying some microspheres on the top of the observed object, which is concurrent with our calculations [5][6][7]. However, these operational modes are not so operationally practiced.…”
