Abstract: A process monitoring system determines a spectral response of a process material. This system has a tunable laser for generating an optical signal that is wavelength tuned over a scan band and an optical probe for conveying the optical signal to the process material and detecting the spectral response of the process material. The optical probe expands a beam of the optical signal to a diameter of greater than 10 millimeters. This avoids one of the difficulties with monitoring these process applications by ensuring that the spectroscopy measurements are accurate and repeatable. It is desirable to sample a relatively large area of the processed material since it can be heterogeneous. Additionally the large area mitigates spectral noise such as from speckle.

Abstract: Systems and methods for increasing the quantum efficiency of a photocathode used in an intensified an intensified array detector with a photocathode, such as a charge-coupled device (ICCD) are presented. A quantum efficiency enhancement device is disposed in front of an ICCD and is configured to enable or facilitate an increase in the angle of incidence of incoming rays incident on the photocathode. The ICCD itself may be tilted to achieve an increased angle of incidence, and such tilting is preferably only in a direction in which pixel columns of the ICCD extend such that a plane of incidence of incoming light to the ICCD is perpendicular to a direction of wavelength dispersion. The quantum efficiency enhancement device may include re-imaging optics, an optical tilt compensator and optical coupler.

Abstract: To increase the sensitivity of detector arrangements, it is known that light deflection elements in the form of a line arrays having spherical elements may be used to focus incident light onto light-sensitive regions of the detector. Manufacturing such line arrays is complex and cost intensive, especially in small lot numbers. The increased sensitivity of the detector array can be achieved easily and inexpensively by using a novel light deflection element. The detector arrangement therefore has a light deflection element having light entrance surfaces, deflecting incident light by refraction onto light-sensitive regions of the detector. Light entrance surfaces of the light deflection element are inclined with respect to one another and are designed as planar surfaces. The detector arrangement is suitable in particular for detection of light emanating from a specimen in a microscope, preferably in a laser-scanning microscope.

Abstract: An array microscope scans a slide in rapid sequence at different wavelengths to record multiple spectral images of the sample. Full spatial resolution of the image sensor is realized at each color because pixels are not shared between spectral bands. The object and detector are placed at conjugate distances selected to produce substantially equal magnification with minimum chromatic aberration at all wavelengths to ensure registration of all images. Spectral analysis is carried out by combining the images captured at each wavelength. The greater-than-RGB spectral resolution provided by the combination of images enables the isolation and display of the effects produced by the contemporaneous use of more than two stains on a tissue for improved pathological analysis.
