This allows high-speed and high-sensitivity live-cell imaging, enabling the best use to be made of the Ti2’s large FOV.
Unsurpassed Nikon optics
Nikon's high-precision CFI60 infinity optics, designed for use with a variety of sophisticated observation methods, are highly regarded by researchers for their superb optical performance and solid reliability.
Apodized phase contrast
Nikon's unique apodized phase contrast objectives with selective amplitude filters dramatically increase contrast and reduce halo artifacts to provide detailed high-definition images.
External phase contrast Ti2-E
The motorized external phase-contrast system enables users to combine phase contrast with epi-fluorescence imaging without compromising fluorescent light transmission by bypassing the need to use phase-contrast objectives. For example, very high NA, liquid immersion objectives can be used for phase-contrast imaging. Using this external phase contrast system, users can easily combine phase contrast with other imaging modalities, including weak-fluorescence imaging such as TIRF and laser tweezer applications.
DIC (Differential Interference Contrast)
Nikon's highly-regarded DIC optics provide uniformly clear and detailed images with high resolution and contrast throughout the magnification range. DIC prisms are individually tailored for each objective lens to provide the highest-quality DIC images for every sample.
NAMC (Nikon Advanced Modulation Contrast)
This is a plastic-compatible, high-contrast imaging technique for unstained, transparent samples such as oocytes. NAMC provides pseudo-three-dimensional images with a shadow-cast appearance. The direction of contrast can be easily adjusted for each sample.
Auto Correction Collar Ti2-E
Changes in sample thickness, cover glass thickness, refractive index distribution in the sample, and temperature can lead to spherical aberration and image deterioration. The highest quality objectives are often equipped with correction collars to compensate for these changes, and precise positioning of the collar is critical in achieving high resolution, high contrast images. This new auto correction collar utilizes a harmonic drive and automatic correction algorithm that enable users to easily achieve precise collar adjustment to achieve optimum objective performance every time.
The Lambda series objectives, utilizing Nikon's proprietary Nano Crystal Coat technology, are perfect for demanding, low-signal, multi-channel fluorescence imaging that requires high transmission and aberration correction over a wide wavelength range. Combined with new fluorescence filter cubes that offer improved fluorescence detection and stray light countermeasures such as the Noise Terminator, the Lambda series objectives demonstrate their power in weak signal observations such as single-molecule imaging and even luminescence-based applications.
Volume Contrast New
Volume Contrast technique utilizes a series of label-free, brightfield images captured at various Z-depths to assemble a phase distribution image.
Volume Contrast renders cells easily identifiable as objects for automated counting and area analysis. As this method utilizes brightfield imaging, Volume Contrast enables in-line, non-destructive analysis of cells, suitable for a wide variety applications. Note. For Ti2-E only.
Features of Volume Contrast（VC)
Accurate identification of cells from label-free cultures for automated cell counting and area measurements.
Negligible Meniscus Effect on Cell Identification
Phase contrast images are negatively impacted at the edges of wells due to the meniscus effect. Volume Contrast bypasses this effect and enables cells at the edges of wells to be clearly identified, resulting in increased cell counts and improved statistics.
Even the slightest change in temperature and vibrations in the imaging environment can greatly impact focus stability. The Ti2 eliminates focus drift using both static and dynamic measures to enable faithful visualization of the nanoscopicand microscopic world during long time-lapse experiments.
Mechanically redesigned for ultra-high stability Ti2-E
In order to improve the focusing stability, both Z-drive and PFS autofocusing mechanisms have been completely re-designed.
The new Z-focusing mechanism is smaller and positioned adjacent to the nosepiece to minimize vibrations. It remains adjacent to the nosepiece even in an expanded (staged-up) configuration, ensuring stability for all applications.
The detector portion of the Perfect Focus System (PFS) has been detached from the nosepiece in order to reduce mechanical load on the objective nosepiece. This new design also minimizes heat transfer, which contributes to a more stable imaging environment. Towards this end, the power consumption of the Z-drive motor has also been reduced. Combined, these mechanical redesigns result in an ultra-stable imaging platform, perfectly suited for single-molecule imaging and super-resolution applications.
Real time focus correction with the PFS: Simply perfect Ti2-E
The Perfect Focus System (PFS) automatically corrects focus drift caused by temperature changes and mechanical vibrations, which can be caused by a variety of factors including the addition of reagents to the sample and multi-position imaging.
The PFS maintains focus by detecting and tracking the position of the coverslip surface in real time. Unique optical offset technology allows users to easily maintain focus at a desired position offset from the cover slip surface. The PFS automatically and continuously maintains focus by means of a built-in linear encoder and high speed feedback mechanism, providing highly reliable images even during long-term, complex imaging tasks.
PFS is compatible with a wide range of applications, from routine experiments involving plastic culture dishes to single-molecule imaging and multi-photon imaging. It is also compatible with a wide range of wavelengths, from ultraviolet to infrared, meaning it can be used for multi-photon and optical tweezer applications.
Water Immersion Dispenser Ti2-E
The performance of long-term imaging using the PFS together with water immersion objectives can be increased by using the new Water Immersion Dispenser. The Water Immersion Dispenser automatically applies the appropriate amount of pure water to the tip of an objective, preventing the immersion liquid from drying out and overflowing during experiments. It is compatible with all types of water immersion objectives and helps to stably provide high-resolution, high-contrast and aberration-corrected time-lapse images over long periods of time.

The Ti2's Assist Guide function provides interactive step-by-step guidance for microscope operation. The Assist Guide can be viewed on a tablet or PC, and integrates real time data from built-in sensors and an internal camera. The Assist Guide is designed to help users through alignment procedures for both experiment setup and troubleshooting.
Automatically detect errors Ti2-E/A
The Check Mode allows users to easily confirm, on either a tablet or PC that all the correct microscope components are in place for their chosen observation method. This capability eliminates time and effort normally required for troubleshooting when the desired observation method is not achieved. This functionality is particularly advantageous when multiple users are involved, each with the potential to make unexpected changes to the microscope settings. Custom check procedures can also be pre-programmed.
The Ti2 has been completely redesigned, from the overall body design to the selection and placement of every button and switch, for the ultimate in user experience. The controls are easy to use even in the dark, where the majority of imaging experiments are conducted. The Ti2 provides an intuitive and effortless user interface so researchers can focus on the data and not on microscope control.
Thoughtfully designed layout for microscope control Ti2-E Ti2-A
The placement of all of the buttons and switches are based on the type of illumination they control. Buttons that control diascopicobservation are positioned on the left side of the microscope and those that control epi-fluorescence observation are on the right side. Buttons that control common operations are on the front panel. This use of zoning provides an easy-to-remember layout, a desirable feature when operating the microscope in a dark room.
① Shuttle switch (Ti2-E)
Shuttle switches have been incorporated into the design to control devices such as the fluorescence filter turret and objective nosepiece. These types of switches emulate the feel of manually rotating these devices, for intuitive control. Additional functionality can be incorporated into these shuttle switches so that a single switch can operate multiple related devices. For example, the shuttle switch for the fluorescence filter turret not only rotates the turret but also opens and closes the fluorescence shutter when the user presses the switch. It is also possible to program these switches to operate a barrier filter wheel and the external phase contrast unit.
② Programmable Function button (Ti2-E/A)
Conveniently located Function buttons allow customization of the user interface. Users can select from more than 100 functions, including control of motorized devices such as shutters and even signal output to external devices via the I/O port for triggered acquisition. Mode functions, which enable instant changing of observation methods by storing the settings of each motorized device, can also be assigned to these buttons.
③ Focusing knob (Ti2-E)
A focus acceleration button and a PFS engagement button are provided adjacent to the focusing knobs. The two buttons are easily identified by touch because of their different shapes. Focusing speed is automatically adjusted for the objective in use, enabling stress-free operation by maintaining an ideal focusing speed.
Intuitive control with joystick and tablet
