Abstract: A dual source system and method includes a high power laser used to determine elements in a sample and a lower power device used to determine compounds present in the sample. An optical subsystem directs photons from a sample to a detector subsystem after laser energy from the laser strikes the sample along an optical path. After energy from the device strikes the sample protons are directed to the detector subsystem along the same optical path. The detector subsystem receives photons after laser energy from the laser strikes the sample and provides a first signal, and receives photons after energy from the device strikes the sample and provides a second signal. A controller subsystem pulses the high power laser and processes the first signal to determine elements present in the sample, energizes the lower power device and processes the second signal to determine compounds present in the sample.

Abstract: The present disclosure relates to limitation of noise on light detectors using an aperture. One example embodiment includes a system. The system includes a lens disposed relative to a scene and configured to focus light from the scene onto a focal plane. The system also includes an aperture defined within an opaque material disposed at the focal plane of the lens. The aperture has a cross-sectional area. In addition, the system includes an array of light detectors disposed on a side of the focal plane opposite the lens and configured to intercept and detect diverging light focused by the lens and transmitted through the aperture. A cross-sectional area of the array of light detectors that intercepts the diverging light is greater than the cross-sectional area of the aperture.

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.
