attoCFM I
PAGE 124 attoCFM I low temperature confocal microscope , free-beam optics
The attoCFM I has been developed to offer a maximum amount of flexibility for a convenient adaption to a large number of different quantum optics applications . This is realized by an external optics head , positioned outside the cryostat . Furthermore , the free-beam optical design allows for completely independent adjustment of the excitation and collection port . Therefore , applications such as Raman
spectroscopy become accessible by appropriately filtering of the excitation and detection signals . The easy handling opens up new possibilities in quantitative surface characterization in the sub-micron range . The attoCFM I can optionally be equipped with an interferometric encoder for closed loop operation with 1 nm resolution , and an ultra large range scanner with 125 µ m scan range at 4 K .
