Abstract
A scanner arrangement, suitable for use in laser scanning microscopes, for scanning a scanning field (42) by means of optical radiation (5). It is equipped with at least one scanner (1), which comprises a scanning mirror (2) that is tiltable about one or two scanning axes (3, 4) and means for rotating the scanning field, for scanning a size-variable scanning field and for centring the scanning field centre (43) when panning. The arrangement includes a mechanical pivot device (7) for rotating the scanning field (42). The pivot device is arranged to pivot the scanner (1) about a pivot axis (8). Pivoting is implemented through angular dimensions that correspond to an intended rotation of the scanning field.
Claims14
Scanner arrangement for deflecting optical radiation over a scanning field formed in an object plane, comprising:
- at least one reflective beam deflection element having a scanning mirror that is tiltable about one or two scanning axes;
- means for rotating the scanning field within the object plane;
- a mechanical pivot device for rotating the scanning field, said pivot device being arranged to pivot the beam deflection element about a pivot axis, wherein pivoting through certain angular dimensions corresponds to an intended rotation of the scanning field;
- and
- means for compensating offset of the scanning field centre from its original position in the object plane as a consequence of pivoting.
