The experimental quest on dimension and material of microsphere for photonic jet microscopy

Abstract

Abstract Our previous studies have shown the potential of applying photonic jet for microscopy. However, some parameters concerning the microsphere must be determined before practicing photonic jet for microscopy. This manuscript reports our quest for dimensions and materials of microsphere that fitted for on an optical microscope, experimentally. The main directive in our quest is the largest magnification or the best resolution of the image obtained by the microsphere. We find that if the refraction index ratio is getting larger or closer to two, it needs larger microspheres. On contrary, if the refraction index ratio is closer to one, it needs smaller microsphere.
