Overview
This chapter explains the overview of the perfect focus system.
1 Overview
Nikon perfect focus system is provided for Nikon inverted microscope ECLIPSE TE2000-E to track the focus
automatically.
This system detects the boundary surface between the cover glass* and aqueous solution of the specimen. When a dry
type objective is used, this system detects the boundary surface between the cover glass and air. And the detection is
performed by using a near infrared light (infrared band), which does not interfere with general observations, and controls
the focus of the microscope by tracking the vertical fluctuation of the boundary surface. That is, this system is free from
the specimen’s state change and color fading during fluorescent observation and keeps the focus at a steady position by
automatically correcting the minute defocus caused by changes over time, stage movement, and so on. This system is,
therefore, suitable for continuous observations and capturing images with a camera for changes of a living organic cell
and so on.
*: The cover glass is the bottom part of the glass bottom dish.
2 Features
• As the infrared band light is used for the focusing control, which is insensitive to a specimen and does not interfere
with the fluorescent microscopy, the focus-keeping and the fluorescent microscopy can be done simultaneously.
• The focus position can be adjusted manually with the optical offset function.
• The vertical position (position on the Z-axis) of the nosepiece and the focus offset amount for each objective can be
registered.
• The focus can be kept on the image-capturing specimen located at any place in the view field.
• Automatic adjustment of the defocusing can be done for any type of observation cameras and methods including
observation by naked eyes, that is, without restriction by the camera type, not alike the image contrast method.
3 Offset function
This system detects the boundary surface between the cover glass and aqueous solution of the specimen using a near
infrared light (infrared band) and controls focusing using the boundary surface as the reference position.
The objective of the microscope tracks the up/down changes of the boundary surface caused by the defocusing over
time and the stage movement when controlling the focus.
To focus on a desired point on the specimen, adjust the OFFSET knob on the perfect focus controller.
The offset amount is defined as the deviation of the focus point from the reference position (boundary surface) to where
the focus point is moved by adjusting the OFFSET knob. Keeping the specified offset amount, focusing can be controlled
so as to track the up/down changes of the boundary surface. The range of the offset amount depends on the objective. In
particular, when a water or oil immersion type objective is used, the offset amount is limited in the downward.

4.3 Not-suitable specimen
The following specimens are hard to be observed. Because the focus control cannot be performed by reason of that the
reflection signal of the infrared is weak or the scattered light is strong.
(1) Fixed specimen
Usually a fixed specimen is filled with mounting medium. And this medium has a high refractive index. So, the
difference of the refractive indexes between the cover glass and the specimen is relatively small. Therefore,
enough reflection for the detection cannot be get.
(2) Sliced specimen
A sliced specimen is thick and its scattered light is strong. So, the reflection is hard to detect because the reflection
from the boundary surface is relatively weak.
(3) Specimen of strong reflection or strong light scattering
In addition to the sliced specimen, if a specimen has a strong light scattering, the weak reflection from the boundary
surface is hard to detect as is the case of (2).
(4) Cells touching the bottom glass with the thickness of 170 µm or more
When a dry type objective is used for a specimen with a thick bottom glass, the offset amount may be insufficient to
observe the boundary surface. So, the focusing range cannot be secured. (For an oil immersion type objective, the
boundary surface may be detected. But this method is not recommend. Use the cover glass of No.1S.)
(5) Specimen mounted on a plastic dish
A plastic dish is not recommended because the boundary surface is not suitable for the detection.
(6) Specimen mounted on a dirty cover glass
This system detects the surface of the cover glass and controls focusing. So, if the surface of the cover glass is not
clean, it will adversely affect the detection. Please clean the cover glass beforehand.
