Abstract: The invention is based on the knowledge that the quasi-static deflection of a dispersive element can also be obtained in a miniaturization, in that a higher degree of insusceptibility against vibration and shock can be obtained when a suspension is used for the dispersive element, which biases the same into a resting position, as well as for the deflection a means for holding the dispersive element in a deflected position, such that an equilibrium of powers is established between the holding force and the biasing force. In that way, after shock and vibration, the dispersive element always returns to the position defined by the holding force. Therefore, an inventive spectrometer comprises a dispersive element for spectrally decomposing a light beam, whose spectral distribution is to be determined, into spectral components, as well as a suspension for supporting the dispersive element and for biasing the same into a resting position with a biasing force, when the dispersive element is in a deflected position. A control means controls a holding means to vary the deflected position, so that different spectral components become detectable for a detector of the spectrometer.

Abstract: A spectrometer, or a spectral instrument using multiple non-interfering optical beam paths and special optical elements. The special optical elements for use with the instrument are used for directing the optical beam and/or altering the form of the beam. The instrument has the potential, depending upon the totality of the optical components incorporated into the instrument, to be a monochromator, a spectroradiometer, a spectrophotometer and a spectral source. The spectral instrument may further be a part of the spectral system. The system may include the spectral instrument, a power module and means for remote control of the instrument. Such remote control may be by use of a personal computer or a control system dedicated to the control, measurement and analysis of the collected information. The multiple non-interfering beam paths are created using specially designed optical elements such as a diffraction grating, a splitter box, a zero back-lash drive system for movement of the grating element. The orientation of and a physical/spatial relationship between the field lenses, slits, return mirror, reflecting prism, turning lenses all define the multiple, preferably two paths. Particularly, there is a double pass through the grating to increase dispersion, reduce scatter while maintaining a perfect temperature independent spectral match for the second pass. Using the same grating twice reduces scatter by about a factor of 1000, increases the dispersion by a factor of two, and eliminates any temperature-related mechanical spectral drift which often is present with two separate monochromators. Because of the specially designed grating structure, the grating can cause the concurrent diffraction of a plurality of incident optical beams, each of which beams have different angles of incidence and different angles of reflection. The path of the incident and the reflected beam to and from the grating is “off-axis”. That is, the beams going to and from the grating do not use the optical axis of the grating structure.

Abstract: A spectrometer has a source of illumination radiation having a plurality of spectral wavelengths, a bandpass filter, a dispersive beamsplitter disposed in an optical path of said source of illumination radiation, an illumination radiation rejection filter, and a spectrograph disposed in a path of radiation from a sample illuminated by illumination radiation from said source of illumination radiation. The dispersive beamsplitter, the bandpass filter, the illumination radiation rejection filter and spectrograph are tunable in correspondence to a selected one of the plurality of spectral wavelengths of the source of illumination radiation. The dispersive beamsplitter directs the selected one of the plurality of spectral wavelengths of illumination radiation to a sample and directs elastically scattered and reflected radiation from the sample out of a measurement beam of light emanating from the sample. The inelastically scattered light passes through the dispersive beamsplitter essentially unaffected and is directed to the illumination radiation rejection filter and the spectrograph.

Abstract: The invention concerns a device for adjusting angular play on a predetermined angular range of an optical element mobile in rotation relative to a frame. Said device comprises a contact piece (3), integral with the optical element, and an elastic steady arm (4). The steady arm has a first end (41) fixed to the frame and a second end (42) co-operating with the contact piece when the mobile element is oriented in the predetermined angular range, at least when the mobile element enters said angular range in the rotational direction (S1), such that the steady arm exerts on the mobile element a counter-torque. Said second end does not co-operate with the contact piece when the mobile element is oriented outside the angular range.
