    Abstract: A spectrophotometer measures optical absorption of light by a sample received in a sample cell. An array of optical elements disperses the light over a spectral pattern, and a fiber optic beam splitter splits light at a selected spectral band into a reference component and a test component. Detectors measure the intensity of the reference component and the test component after the test component passes through the sample. The fiber optic beam splitter includes a plurality of strands arranged with first ends terminating in a common circular area. Opposite ends of peripheral strands are collected into a first set that transmits the test component while the remaining strands for a second set that transmits the reference component. Preferably, there is a single, central, large strand surrounded by smaller strands. Two emitters are provided for light of two different types, such as visible and UV. The optical array forms a collimated beam having an inner core of one type of light and an outer shell of the other. Specially constructed optical elements then reflect and refract the collimated beam. A motor drives a mirror to scan the beam across an optical slit positioned in front of the beam splitter to select a desired spectral band.

    Abstract: The invention contemplates a two-dimensional spectrometer wherein a single catadioptric system is both the collimator and the camera for two-pass use of any two-dimensionally dispersed spectrometer. Off-axis aberration effects are minimized by arranging a fiber optic as the light-entrance aperture, on the central optical axis of the spectrometer and in close proximity to or centrally inserted in a two-dimensional array detector at the image plane. In other words, the grating of the spectrometer is also a reflector which folds admitted and dispersed light for return to the image plane along essentially the same path and through the same optical elements as are used on the incoming pass of light to the diffraction grating. The invention is shown for its applicability to each of various types of two-dimensional spectrometer-design configurations.

    Abstract: A filter spectrograph unit for use in a micro-Raman spectrometer system or a remote sensing system is formed by combining an infinitely variable spectral line rejection filter (having appropriate entrance optics) functionally and operatively with a dispersing spectrograph. The line rejection filter is a modified form of a zero-dispersion double monochromator having an input light signal including laser light scattered from, for examle, minute Raman-active particles. The modified double monochromator includes an acylindrical mirror positioned so that the laser line will exit through an aperture in the mirror and all other spectral lines will be reflected and reformed by the modified double monochromator into an output light signal containing all of the original spectral information, less the rejected laser line. The dispersing spectrograph is integrally coupled to the modified double monochromator and produces from the output light signal a display of the entire Raman spectrum suitable for parallel readout and rapid data analysis.

    Abstract: Disclosed are a fluorescence microscope light source apparatus and a fluorescence microscope capable of obtaining high-luminance light in a wavelength of 500 to 550 nm and having reduced background noise when a sample is observed. The fluorescence microscope light source apparatus to be installed in a fluorescence microscope including an illumination light bandpass filter includes: a laser diode that emits blue light as excitation light; a phosphor that converts the excitation light from the laser diode into illumination fluorescence with a wavelength region of 500 to 550 nm; an optical system that extracts the illumination fluorescence from the phosphor; a first condenser lens that condenses the excitation light onto the phosphor; a light guide body having one end face on which the illumination fluorescence is incident and the other end face from which the illumination fluorescence exits; and a second condenser lens that condenses the illumination fluorescence onto the one end face of the light guide body. A band-elimination filter that blocks or attenuates light, out of the illumination fluorescence, in a wavelength region including a transmission maximum wavelength and including no transmission minimum wavelength in the illumination light bandpass filter is provided on a light path of the illumination fluorescence.
