Abstract: A coherent anti-Stokes Raman scattering microscope imaging apparatus, comprising: a laser light source (21), a two-dimensional oscillating mirror assembly (22), a first light dichroic mirror plate (23), an objective lens (24), a sample translation platform (25), a collection device (26), and a data processing module; the laser light source (21) is used for producing a first laser beam and a second laser beam; the first laser beam and the second laser beam are coaxially emitted; the first laser beam and the second laser beam are incident on the two-dimensional oscillating mirror assembly (22), and the two-dimensional oscillating mirror assembly (22) adjusts the optical path of the first laser beam and the second laser beam; the first laser beam and the second laser beam leaving the two-dimensional oscillating mirror assembly pass in sequence through the first light dichroic mirror plate (23) and the objective lens (24); the objective lens (24) focuses the first laser beam and the second laser beam onto the sample translation platform; the signal light produced on the sample translation platform (25) passes through the objective lens (24), and the collection device (26) produces initial data on the basis of the signal light, and outputs the initial data to the data processing module; the need for beam splitting and wavelength adjustment of a single wavelength laser beam outputted by a laser is thereby avoided.

Abstract: A standard reference material interface for a Raman probe includes a locator including a housing having a first end and a second end, the first end including an attachment portion configured to mate with an attachment portion of the Raman probe. The locator defines a central axis that intersects the first end and the second end. The standard reference material interface also includes a hermetically sealed standard reference material enclosure positioned at the second end of the housing and enclosing a standard reference material. An optical port is positioned within the housing between the Raman probe and the standard reference material relative to the central axis. The optical port includes a window.

Abstract: The present invention relates to a device for the discrimination of biological tissues, such that it is capable of carrying out the discrimination of tissue under complicated operating conditions, for example due to the presence of contaminating elements given off by a cutting operation, due to the presence of moisture in the biological tissue, or due to the presence of a non-controlled atmosphere that interferes with the results of the readings. The invention allows building more complex devices, including cutting instruments, such that it is possible to carry out a surgical intervention in a safe manner by preventing cutting into tissues that are to be avoided during said cutting operation.

Abstract: A compact spectrometer includes an excitation light source configured to generate excitation light and arranged to illuminate a spot on a sample. A dispersive element includes at least one movable component and spatially separates output light emanating from the sample in response to the excitation light into a plurality of different wavelength bands. A moveable component of the dispersive element causes the plurality of different wavelength bands of the output light to be scanned across a detector. The detector includes at least one light sensor that senses the wavelength bands of the output light and generates an output electrical signal in response to the sensed output light.
