    Abstract: An adjustable slit plate assembly for a monochromator is formed by two identical metal plates (P1, P2) each having a set of slits (EX1 to EX6 and EN1 to EX6 respectively) with all the slits disposed on a common circle. The plates (P1, P2) are located and supported on a disc (SM) on a rotatable shaft (SH) at the axis (A) of the circle. The slits are each of minimum length to pass a radiant beam of given energy through the monochromator and each set of slits occupies an arc of substantially minimum length. The shape of each plate is substantially a sector of a further circle whose radius and arc are the minimum necessary to accommodate the slits and the axis. The complete configuration of the plates is formed by etching in a single operation, and a greater number of slit sets can be formed together from a plate of given area than for the prior art case in which the two sets of slits for a slit assembly are formed in a single plate in the shape of a complete disc. A significant cost reduction in the slit assembly is thus achieved.

    Abstract: There is disclosed a flexible mounting structure, rigidly supported at only two locations, for providing opposed precision motion of at least two mounting surfaces oppositely disposed upon the mounting structure in response to a force coupled symmetrically applied to the mounting structure. A pair of resilient connecting members, each having one of the two locations for support, and a pair of rigid mounting rails, each rail having at least one of the mounting surfaces disposed thereon, are connected to form a parallelogram whereby the mounting surfaces are substantially parallel. A rotatable shaft is disposed at right angles and adjacent to the rigid mounting rails. A drive tape is connected between the rotatable shaft and each of the rigid mounting rails in such a manner that as the shaft is rotated, each drive tape wraps around the shaft to provide the symmetrical force couple which moves the mounting rails. A cam follower arm is attached to the rotatable shaft and a cam roller bearing attached to the arm rides on a rotatable cam. Optical elements attached to the mounting surfaces transverse a precision path in accordance with the motion of the mounting rails.
