Abstract: An inclined mirror is provided in a cylindrical housing which has an open end and a closed end. An optical planar glass plate or window is mounted at the open end of the cylindrical housing. A laser beam enters the housing through the window and is reflected off the inclined mirror. The reflected beam leaves the housing through a side aperture in the housing. The cylindrical housing is rotated to scan the beam through a range of angles. Rotation of this optical system induces astigmatism in the beam due to the deformation of the inclined mirror at high rotational speed. If the window is tilted so that the entering laser beam is no longer normal to the window surface, then the window will induce a degree of astigmatism in the laser beam. The angular position of the window can be adjusted relative to the inclined mirror, thus compensating for the dynamic astigmatism due to rotation. A wedge is added to the planar surface of the tilted window to compensate for the coma induced in the beam by the tilt of the planar window.

Abstract: A centrifugal spindle is described comprising a hollow shaft (1) having a collet (2) at one end for gripping a tool shank (12) and a centrifugal loading means (3) housed within the shaft (1). The loading means comprises two coaxial pistons (4,5) spaced from each other and linked by flexible connecting members (6) and intermediate bob weights (7). One piston (4) is secured axially to the hollow shaft (1) while the other piston is secured to the collet so that rotation of the shaft (1) causes the weights (7) to move radially outwards under centrifugal force to draw the piston (5) and collet (2) into the hollow shaft (1) gripping the tool shank (12). The collet may have spring loaded jaws forcing them into the closed position.

Abstract: A rotatable mirror assembly is described comprising a spherical housing (1) rotatable about an axis (A). The housing contains a mirror (2) bonded in the rear end of the housing. The housing at the front of mirror (2) has a flange (3) while a second enlarged flange (4) is formed at the rear of the mirror (2) the front of the mirror (2) has a sloping end face (5) at an angle of 45.degree. of the rotary axis (A) which fives toward an opening (6) in the side of the housing (1). The opening (6) in a first embodiment is closed by an optically flat sapphire window (7) bonded into the opening (6) and in a second embodiment has a curved lens (17) mounted in the aperture. The improved assemblies reduce noise generation of high speed rotating mirrors and prevent the deposit of small particles of dust on the mirror surface.
