Abstract: Disclosed is an apparatus and method for fluorescence excitation and detection. The apparatus comprises one or more light sources for providing excitation light for fluorescence excitation at an observation spot along an optical axis for excitation, an optical collection element for collecting fluorescence light generated by the excitation light at two or more different observation spots into two or more different measurement channels with an optical axis for collecting non-parallel to the optical axis for excitation of each of the one or more light sources, and, for each of the two or more measurement channels and thereby for each of the two or more observation spots, a dedicated optical detector for detecting fluorescence from the fluorescence light collected by the optical collection element.

Abstract: A hyperspectral detection approach is used in combination with narrow linewidth illumination for fluorescence excitation. A more efficient fluorophores excitation and image capturing may be provided, and thus high-quality data for subsequent hyperspectral analysis may be obtained. An apparatus, a method, a system and a computer program are disclosed.

Abstract: An apparatus for stacking and coating of very short cavity laser diode arrays. The apparatus includes an array holder fixture to securely hold the very short cavity laser diode arrays and spacer arrays, and a stacking plate. The array holder fixture including a top-side presser to secure a stack of very short cavity laser arrays and spacer arrays from a first end of the stack, a bottom-side presser to secure the stack of very short cavity laser arrays and spacer arrays from a second end of the stack, and a pair of side clamps. The array holder fixture is operatively coupled to the stacking plate during the stacking of the very short cavity laser diode arrays and spacer arrays.

Abstract: A method for re-configuring a biomedical laser device. The biomedical laser device is pre-configured to be operable in one or more operational modes, and is provided with set of operational parameters that are employed for at least one of: given medical procedure, given medical treatment, activation of given drug, illumination of given dye. The method includes collecting information indicative of light output properties of biomedical laser device measured during given operational mode; detecting deviation in measured light output properties with respect to predefined light output properties for given operational mode; determining new set of operational parameters that are to be employed for at least one of: new medical procedure, new medical treatment, activation of new drug, illumination of new dye; and sending new set of operational parameters to biomedical laser device for re-configuring biomedical laser device to be operable in a new operational mode.
