attoCFM II
PAGE 136 attoCFM II low temperature confocal microscope , highly stable and compact
The attoCFM II is a compact confocal microscope , which is designed for in-situ analysis . The microscope is highly stable at low temperature , high magnetic field , and high vacuum . 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 refilling 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 . The attoCFM II is available with interferometric encoder for closed loop operation .
