Nikon TE2000-PFS Perfect Focus System
Always in perfect focus. When the PFS feature is turned on, the position of the
coverslip is always detected during observation, and the data is continuously
fed back to the focusing mechanism thanks to Nikonís proprietary COF (Continuous
Optical Feedback) technology.*
Perfect focus to the plane of interest. Focus is continuously corrected at any
plane of interest throughout the specimen by the Optical Offset feature*.
High-precision focusing. By combining the highly sensitive focus detection
system and the extremely accurate Z-axis control system of the TE2000-E,
focusing precision of less than 1/3 the focal depth of the objective is
Long-term focal maintenance. Just turn the PFS on - consistent focus will be
maintained, even for several days.
Focus detection with infrared light. PFS uses a 770nm wavelength LCD (which does
not affect fluorescence observation) for focus detection. Therefore,
observations and focus maintenance are carried out simultaneously, with no
effect on captured images.
Supports all observation methods. PFS is compatible with a wide array of
observation methods, from brightfield, fluorescence to DIC, TIRF, phase
contrast, and others.
PFS strongly supports live cell applications such as Laser TIRF and White-light
TIRF Multi-fluorescence Imaging.
Acclaimed CFI60 objectives. Nikon's CFI60 infinity objectives provide high
numerical apertures and long working distances. Since tube-lens focal length is
200mm, there is no aberration even when various optical components are
introduced into the optical path.
Can be operated from a PC using third-party application software.
Objective anti-collision mechanism prevents objectives from hitting the stage
when changing magnifications.
Five output ports, including a bottom port, are standard and can be easily
switched via motorized control.
