  • Patent number: 10393587
    Abstract: Methods for laser induced ablation spectroscopy are disclosed. A sample site position sensor, and stage position motors can move the stage in three independent spatial coordinate directions, and a stage position control circuit is used to move an analysis sample site to selected coordinate positions for laser ablation. Light emitted from a plasma plume produced with laser ablation can be gathered into a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a broadband spectrometer operable to analyze a relatively wide spectral segment, and a different branch can convey a second portion of the light to a high dispersion spectrometer operable to measure minor concentrations and/or trace elements. Emissions from a plasma plume can be simultaneously analyzed in various ways using a plurality of spectrometers having distinct and/or complementary capabilities.

  • Patent number: 9618449
    Abstract: Modular systems can be used for optical analysis, including in-situ analysis, of stimulated liquids. An excitation module can include a radiation sources, e.g., a laser, LED, lamp, etc. A detection module can include one or more detectors configured to receive spectral and/or temporal information from a stimulated liquid. Such systems can be used to identify or measure optical emissions including fluorescence or scattering. The efficient excitation of liquid samples and collection of emissions from the samples provides substantial, up to four-fold increase in the emission signal over prior systems. In an example, emission measurements can be conducted in an isolated sample compartment, such as using interchangeable modules for discrete sampling, flow-through sampling, or sampling via fiber probe. The systems and methods described herein can be used to characterize natural aquatic environments, including assessments of phytoplankton pigments, biomass, structure, physiology, organic matter, and oil pollution.

  • Patent number: 9618450
    Abstract: An optical sensor may include multiple optical emitters configured to emit light into a fluid sample via an optical pathway. Light from the emitters can cause fluorescence from the sample and/or scatter off of the sample. Scattered and fluoresced light can be received by an optical detector in the sensor via the optical pathway, and used to determine at least one characteristic of the fluid sample. A second optical detector can provide reference measurements of the amount of light emitted to the sample. In one example, the optical detector can detect scattered and fluoresced light simultaneously. In another example, light is emitted and detected alternatingly. The sensor can be part of a system that includes one or more controllers configured to control the emitting and detecting of light to and from the fluid sample. The controller can use detected light to determine at least one characteristic of the fluid sample.

  • Patent number: 9575302
    Abstract: Aberrations in stimulated emission depletion microscopy are corrected using an adaptive optics approach using a metric which combines both image sharpness and brightness. Light modulators (22,32) are used to perform aberration correction in one or more of the depletion path (10), the excitation path (12), or the emission path from sample to detector.

  • Patent number: 9564731
    Abstract: A method of providing supercontinuum illumination in applications involving the excitation of fluorescence, comprising generating, at an optical pump laser, optical pump pulses at a pump pulse repetition rate; selectively controlling with an optical modulator the launch of pump pulses into a nonlinear optical element comprising an optical fiber at a variable, lower repetition rate to thereby selectively control the repetition rate of supercontinuum pulses generated within the optical fiber; and illuminating a sample with supercontinuum pulses to excite fluorescence. The supercontinuum pulses can be wavelength filtered such that the fluorescence is excited with wave length filtered supercontinuum pulses.

  • Patent number: 9545689
    Abstract: Temporal focusing of spatially chirped femtosecond laser pulses overcomes previous limitations for ablating high aspect ratio features with low numerical aperture (NA) beams. Simultaneous spatial and temporal focusing reduces nonlinear interactions, such as self-focusing, prior to the focal plane so that deep (˜1 mm) features with parallel sidewalls are ablated at high material removal rates.

  • Patent number: 9448158
    Abstract: Light collectors for fluorescence microscopy include slab light guides having a specimen volume such as a specimen well configured to retain a specimen. The specimen volume is bounded by a surface of the slab light guide that permits laterally propagating fluorescence to enter the slab light guide and propagate toward a detection or imaging system. Typically, the slab light guide has an elliptical perimeter and the sample volume is situated at a first focus of the elliptical perimeter. A reflector such as a conical reflector is situated at the second focus so as to direct the collected fluorescence to exit the slab light guide.

  • Patent number: 9383490
    Abstract: A light beam is applied to a front surface of an optical depolarizer. The depolarizer rotates the polarization of light received on different surface positions by different amounts, so that the average incoming polarization is scrambled. The depolarizer has a first and second body that transmit first and second polarization components of the beam with mutually different speeds of light. Each body has two wedge shaped parts of variable thickness, corresponding wedge shaped parts in the two bodies providing light paths of substantially position independent lengths, but with variable rotation of polarization. The wedge shape parts of the front body form a concave input surface for the incoming beam. This prevents cross-over of light between the different wedge shaped parts.

  • Patent number: 9360426
    Abstract: Imaging a sample that includes phototransformable optical labels (“PTOLs”) with an optical system having a diffraction-limited resolution volume (DLRV), includes providing activation radiation to the PTOLs to activate a statistical subset of the PTOLs. A density of the PTOLs of the activated subset is less than an inverse of the DLRV. Excitation radiation is provided to the activated subset to excite activated PTOLs. Radiation emitted from the activated and excited PTOLs located at different focal planes of the optical system within the sample is detected with the optical system. The preceding steps are repeated one or more times, each time activating a different statistical subset of the plurality of PTOLs. Three-dimensional locations within the sample are determined, with a sub-diffraction-limited accuracy, of the activated and excited PTOLs based on the radiation emitted from the activated and excited PTOLs that is detected from the different focal planes of the optical system.
