  • Interferometer spectrometer having means for varying the optical path length while maintaining alignment
    Patent number: 5537208
    Abstract: An interferometer which may be used in a Fourier transform infra red spectrometer comprises a beam splitter (10), first and second fixed mirrors (18,26), path length variation means (20), and a folding mirror (16). The optical components are mounted on a casting (8) such that the beam splitter (10) and folding mirror (16) are arranged parallel to each other and the fixed mirrors (18,26) are attached to a single face of the casting in the same plane. The path length variation means (20) comprises two parallel opposed mirrors (22,24) which are rotatable to vary the length of the optical path between the beam splitter (10) and the fixed mirror (26).

  • Device for the transport of carriers from and to a positioning device and selection device for use in such a device
    Patent number: 5085553
    Abstract: A device for the transport of carriers (11,29), in which displaceable containers (27,31) with carriers (29,11) can be coupled with a selection device (33), which is displaceable in vertical direction along a container (27,31) and has two relatively vertical positions with respect to the container (27,31) for the transport of carriers (11,29) at a bringing stage and at a fetching stage, respectively, from and to a positioning device R(B), R(C). The selection device (33) for use in the transport device as described. Use of the transport device with selection device lies particularly in the field of the flexible automation.
