Abstract
A process and a device for the passive alignment of supports, particularly plates which carry optical components. According to the invention, in order to align supports (2, 8), holes (6, 7, 11, 12) are formed in these supports, in correspondence with each other, balls (14, 16) are placed on the holes of one of the supports and these are assembled by placing the holes of the other support onto the balls. The sizes of the holes or of the balls are chosen so as to obtain a pre-set non-zero angle (α) between the assembled supports.
Claims11
A process for the passive alignment of at least one first support (2;
- 241, 242 . . . 24N) and at least one second support (8;
- 261, 262 . . . 26N), this process being characterised in that:
- at least three first holes (6, 7;
- 38, 40, 44) are formed in the first support from a first surface of this first support,
- at least three second holes (11, 12) are formed in the second support from a first surface of this second support, these second holes being able to be facing the first holes when the first surfaces of the first and second supports are placed facing each other,
- balls (14, 16;
- 46, 48, 50) are placed on the first holes respectively, the size of each ball being greater than the size of the first hole corresponding to this ball and than the size of the second hole corresponding to this first hole, and
- the first and second supports are assembled by placing the second holes onto the balls which are on the first holes corresponding respectively to these second holes,
- and in that the sizes of the first and second holes and/or the sizes of the balls are chosen so as to obtain a pre-set non-zero angle between the first surfaces of the first and second assembled supports.
A device for the passive alignment of at least one first support (2;
- 241, 242 . . . 24N) and at least one second support (8;
- 261, 262 . . . 26N), this device being characterised in that the first support includes at least three first holes (6, 7;
- 38, 40, 44) formed from a first surface of this first support and the second support includes at least three second holes (11, 12) formed from a first surface of this second support, these second holes being able to be facing the first holes when the first surfaces of the first and second supports are placed facing each other, the first holes being intended to receive balls allowing the assembly of the first and second supports by placing the second holes onto the balls which are on the first holes corresponding respectively to these second holes, the size of each ball being greater than the size of the first hole corresponding to this ball and than the size of the second hole corresponding to this first hole, and the sizes of the first and second holes and/or the sizes of the balls being chosen so as to obtain a pre-set non-zero angle (α) between the first surfaces of the first and second assembled supports.
