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 uniform illumination lighting module is disclosed herein. In some embodiments, the uniform illumination lighting module comprises a first optical medium, a lower reflective surface disposed adjacent to a bottom boundary of the first optical medium, a concave reflective surface disposed adjacent to a side boundary of the first optical medium, and a light source, wherein at least a portion of the first optical medium is disposed between the light source and the concave reflective surface. In some embodiments, the uniform illumination lighting module further comprises a second optical medium disposed adjacent to a top boundary of the first optical medium. In preferred embodiments, the concave reflective surface is substantially parabolic and the light source is disposed at a parabolic focus of the concave reflective surface.

Abstract: This disclosure relates generally to analytical instruments for measuring one or more properties of specimens or samples to be analyzed and, more particularly, to an analytical instrument with an adjustable optical path length. An analytical instrument may include a specimen support upon which a specimen may rest and a compression plate for controllably adjusting an optical path length of the specimen between the specimen support and the compression plate. In particular, a specimen may contact both the specimen support and the compression plate such that controlling a distance of the compression plate with respect to the specimen support effectively controls the optical path length of the specimen. An analytical instrument may include collimating lenses to collimate electromagnetic energy for transmission through a specimen and converging lenses for directing electromagnetic energy transmitted through the specimen into one or more sensors.
