    Abstract: There is disclosed herein a cell assembly for use in spectrophotometric analysis or detection of a substance within a small sample volume, such as in a capillary sample cell. The assembly comprises a transparent lens having the shape of a ball, sphere or cylinder, referred to as a "ball lens," and which is placed in direct contact or close proximity to the exterior wall of the capillary cell. This lens and cell are mounted together, any may form a removable cell assembly. The small volume may be contained within the ball lens itself. The ball lens serves to concentrate and direct light into the capillary cell. The arrangement also significantly reduces the sensitivity to alignment of replaceable cells thereby permitting easier mounting and replacement of such cells.

    Abstract: A compact lens system for imaging a sample comprising a substrate having a well formed therein. Index matching material is disposed in the well and a lens member is further disposed in the well in optical contact with the index matching material disposed in the well. A spacer member extends from at least one of the substrate and the lower transparent member to define a spacing from a focal point of the lens member, wherein the lens member and index matching material cooperate to image a sample disposed below the lower transparent member.

    Abstract: Raman emissions from a sample may be enhanced by using a microsphere to confine the impinging radiation into a photonic nanojet and thereby increase the intensity of the radiation that is striking the sample. The amount of enhancement may be improved by configuring the diameter and refractive index of the microspheres in conjunction with the dispersion and the wavelength of the radiation to increase the intensity of the beam of radiation in the photonic nanojet.

    Abstract: An analytical instrument may have multiple distinct channels. Such may include one or more illumination sources and sensors. Illumination may be delivered to specific locations of a specimen holder, and returned illumination may be delivered to specific locations of a sensor array. Illumination may first pass a specimen, and a mirror or reflector may then return the illumination past the specimen. Optical splitters may be employed to couple pairs of fiber optics proximate a specimen holder. Such channels may further include a plurality of illumination sources positioned on one side of a specimen holder and a plurality of sensors on the other side. The plurality of sensor may capture image of a specimen and a spectrophotometer may concurrently scan the specimen. A plurality of specimens may be imaged and scanned in a single pass of a plurality of passes. Spherical or ball lenses may be placed in an optical path of the illumination to achieve a desired illumination pattern.

    Abstract: A fabrication cluster can be controlled using optical metrology. A fabrication process is performed on a wafer using a fabrication cluster. A photonic nanojet, an optical intensity pattern induced at a shadow-side surface of a dielectric microsphere, is generated. An inspection area on the wafer is scanned with the photonic nanojet. A measurement is obtained of the retroreflected light from the dielectric microsphere as the photonic nanojet scans the inspection area. The existence of a structure in the inspection area is determined with the obtained measurement of the retroreflected light. One or more process parameters of the fabrication cluster is adjusted based on the determination of the existence of the structure in the inspection area.
