The Nikon Perfect Focus System (0:33)

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 nanoscopic and microscopic world during long time-lapse experiments.


Mechanically Redesigned for Ultra-High Stability (Ti2-E)

pfs

High stability Z-focusing mechanism remains adjacent to the nosepiece even in expanded configurations

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.


Ti2-Stability2

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.


Fourth Generation Nikon Perfect Focus System (Ti2-E)

The newest generation of the Perfect Focus System (PFS) automatically corrects focus drift caused by temperature changes and mechanical vibrations that can be caused by a variety of factors, including the addition of reagents to the sample and multi-position imaging.

The PFS detects and tracks the position of a reference plane (e.g. coverslip surface in the case of immersion objectives) in real time to maintain focus. Unique optical-offset technology allows users to maintain focus at an arbitrary position offset from the reference plane. The user can simply focus on the desired plane and then engage the PFS. The PFS then 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, providing a means for maintaining perfect focus even for multi photon and optical tweezer applications.

Intelligent Assist Guide

pic_23

Built-in sensors detect the status of microscope components

It is no longer necessary to memorize complex microscope alignment and operation procedures. The Ti2 integrates data from sensors to guide you through these steps, eliminating user error and enabling researchers to concentrate on their data.

Continuous display of microscope status (Ti2-E/A)

assist-guide

Shift Your Perspective (0:19)

A collection of built-in sensors detects and relays status information for a variety of components in the microscope. All of the status information is recorded in the metadata when you acquire images with a computer, so you can easily recall acquisition conditions and/or check for configuration errors.

In addition, a built-in internal camera allows users to view the back aperture, facilitating confirmation of phase ring alignment and extinction cross in DIC. It also provides a laser-safe method for aligning lasers for applications such as TIRF.


status-lights

Status lights

Microscope status can be viewed on a tablet and also determined based on status lights on the front of the microscope, enabling status determination in a dark room.


Guidance for Operational Procedures (Ti2-E/A)

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)

check-mode

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.


Intuitive Operation

The placement of all of the buttons and switches are based on the type of illumination they control. Buttons that control diascopic observation 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.

microscope-control

❶ 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.

❷ 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.

❸ 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 (Ti2-E)

The Ti2 joystick not only controls stage movement, but the majority of motorized functions on the microscope, including PFS activity. It can display XYZ coordinates and the status of microscope components, providing an effective means for the user to remotely control the microscope. Motorized functions of the Ti2 can also be controlled from a tablet, connected by wireless LAN to the microscope, providing a versatile graphical interface for microscope control.
