FIBER BASED CONFOCAL MICROSCOPES FOR HIGHEST STABILITY
	The fiber based attoCFM II is a compact confocal microscope, which is designed for long-term analysis. The key-feature of this system is its unprecedented stability allowing ultra stable, long-term investigations over extended periods of time as the excitation and emission radiation is directly coupled via a single mode fi ber into the high NA objective. Similar to the free beam confocal version the design is optimized to reduce light losses to a minimum and to capture the maximum amount of light scattered by the illuminated point of the sample. The one-of-a-kind combination of materials allows absolutely stable single dot measurements at low temperature over weeks, even when refi lling the bath cryostat with liquid Helium. Furthermore, combining the attoCFM II with cryogen-free cooling solutions is easily possible, opening up new possibilities in cryogenic long-term investigations while considerably reducing operational costs.
FIBER BASED CONFOCAL MICROSCOPES FOR TRANSMISSION EXPERIMENTS
	The attoCFM III is the system of choice for customers interested in both reflection and transmission confocal microscopy. The attoCFM III is a fiber based system applying single mode fi bers which couple the radiation directly into the low temperature compatible objectives. These objectives are mounted onto xyz coarse positioners which enable the independent alignment of the excitation and emission radiation above and below the sample. The sample itself is mounted on a scanner with an aperture which allows to scan the sample over a range of 30 x 30 μm at low temperature. The instrument opens up new possibilities in quantitative sub-micron range investigations and routine inspection in extreme environments and is optimized for both reflection and transmission measurements.
