Adjustable mirror support for lasers system - has three support blocks with concave surfaces centred on mirror centre to keep it stationary

摘要

The support includes a flat base (1) on which there are three support blocks symmetrically positioned about a vertical axis (Z) (3,5). A mirror (6) is supported on a mounting (7) which is held on these three blocks. The blocks have spherical concave surfaces, the curvature of each being centred on a point (C) which is also the centre of the mirror. A projecting part (9) of the mirror mounting is received in a block (10) which is able to slide in the first concave surface support (3a). An adjusting screw (11) controls this movement. A similar mechanism (13) allows adjustment of the mirror mounting in an orthogonal direction. The combined system thus allows accurate adjustment of the inclination of the mirror, whilst keeping its centre (C) stationary.
