Ultraviolet PICs Push the Potential of Nonvisible Microscopy
Manipulating ultraviolet light beams is historically difficult and costly. As it relates to imaging, bulk optics in the UV range are expensive because they require unique materials, such as quartz, magnesium fluoride, or fused silica, to ensure aberration-free imaging with necessary degrees of focus and resolution. And, from a technical perspective, UV imaging microscope objectives with a high numerical aperture, which are required for high-resolution microscopy (operating below 360 nm), are...
