Abstract: A microscopy optoelectronic device for reconstructing a three-dimensional model of a sample, which can be connected to any PC in order to obtain three-dimensional surface micro-reliefs, includes a portable device body, having a casing and a frame supporting: a digital optical sensor; an optical group, coupled to the sensor including an objective lens directed towards a distal end of the device body, faceable towards the sample; a motor that translates the optical group and sensor with respect to said frame; a connector to connect the device body to an energy source and to a device that controls the position of the optical group and to transmit the digitalized images; and a light source that provides diffused lighting at the objective lens arranged to surround a front region with respect to the objective lens and also includes a luminescent and diffusing surface having a tubular portion coaxial to the optical group.

Abstract: A system for evacuating containers. The system includes a base housing defining a recess having a vacuum inlet port in communication with a vacuum source. An inner door is hinged to the base housing and is sized to cover the recess when in a closed position, and an outer door having a sealing member is hinged to close over the inner door. A vacuum nozzle extends at least partially between the inner and outer doors and is in communication with the recess. The inner and outer doors cooperate to retain a flexible container therebetween and around the nozzle so that the nozzle is positioned for fluid communication with an inside of the container. A removable drip pan is positioned to retain fluids drawn by the nozzle.

Abstract: An apparatus for the generation of variable duration laser pulses comprising an optical cavity delimited by two mirrors, one of which is a total reflection mirror and the other a partial reflection mirror, and containing an active medium with an appropriate excitation system. An optical shutter capable of inducing a Q-switching mode is provided between the total reflection mirror and the active medium. The active medium is optically connected with said total reflection mirror by optical fibre sections having different lengths and may be interchanged in the optical path so as to vary the duration of the pulses emitted by the laser when it operates in the Q-switching mode.

Abstract: An apparatus for the generation of variable duration laser pulses comprising an optical cavity delimited by two mirrors, one of which (7) is a total reflection mirror and the other (1) a partial reflection mirror, and containing an active medium (4) whit an appropriate excitation system. An optical shutter (2) capable of inducing a Q-switching mode is provided between the total reflection mirror (7) and the active medium (4). The active medium (4) is optically connected with said total reflection mirror (7) by means of different lengths of optical fibre section (F1, F2, Fn) that may be interchanged in the optical path to vary the duration of the pulses omitted by the laser when it operates in the Q-switching mode.
