Tabletop installation

The space saving and lightweight design of TM3000 means it can be conveniently installed on a table”. No cooling water is needed, so installation is quick and easy and requires only a standard 100-240 V AC power supply.

Topographic imaging with a large depth of focus

Complex specimen structures are easily observed with a resolution and depth of focus far beyond what is achievable by optical microscopy.

Environmentally-friendly pumping system

The TM3000 features a dry (oil-free) vacuum system, consisting of a diaphragm pump for rough evacu- ation and a high performance turbo-molecular pump for main pumping.

Large specimen handling

The large specimen stage allows mounting of a specimen up to 70 mm diameter and 50 mm thick. X/Y specimen motion: +17.5 mm.

Fast specimen exchange

The high-performance vacuum system provides fast pump- down, but specimen exchange also requires chamber venting. It takes just 1 minute to vent the TM3000 specimen chamber, twice as fast as the TM-1000.

Comprehensive auto-functions, with one-click “Start".

Imaging with the TM3000 couldn’t be simpler. Pressing the “Start" button automatically turns the beam on, adjusts focus, brightness and contrast and displays the image at an easy-to-view starting magnification of 100x.

Smooth magnification adjustment

Since magnification is increased simply by narrowing the scanned area, continuous magnification adjustment from x15 to x30,000 is achieved by simply dragging the mouse - making it quick and easy to find the area of interest.

Preset magnification

Frequently used magnifications can be saved in memory (preset). The magnification can be changed to a preset value with a click of the mouse.

Motorized stage version

With the optionaI* motorized specimen stage, all functions of the TM3000 can be operated using the mouse alone. Sample navigation can be performed through the user interface - either by double-clicking a desired destination on the image or by clicking the stage move arrows.

The versatile TM3000 can be used  for almost  any type  of specimen.

Even non - conducting specimens  or sample  containing moisture can be imaged directly, throughout the whole  magnification range of x15  to x30.000, without any special sample preparation

Image non-conducting specimens with ease.

When an electrically non-conducting specimen is observed with a high-vacuum SEM, electrons accumulate on the specimen surface causing a charge-up phenomenon, which prevents normal imaging. Conventionally, to avoid this problem, the sample is usually vacuum coated with a thin layer of metal before observation. This process is not only time consuming, but the metal coating can interfere with imaging and EDX analysis. The TM3000 overcomes this problem with the “charge-up reduction mode"— using low-vacuum operation to eliminate the charge-up effect.

Low-vacuum microscopy

By utilizing a low vacuum level inside the specimen cham-ber, more gas molecules are present. These gas molecules M can collide with the electron beam to generate positive ion + and electrons e. Each positive ion + can be neutralized by one of the excess electrons - on the speci-men surface. In this way the excess electrons on the surface of the sample are removed and the charge-up effect is eliminated or reduced.

Charge-up reduction mode

The TM3000 can operate either in "standard mode” or "charge-up reduction mode" depending on the extent of the specimen charging.

Compositional imaging

In addition to traditional topographic imaging, the TM3000 can produce compositional images, where the different brightness levels represent different composition in the sample. In this mode, higher brightness corresponds to higher atomic number.

Tools for measurement and annotation

- Distance measurement: Distance can be quickly and easily measured by dragging the mouse between two points of interest.

- Graphics/comment input: Simple graphics and comments can be added to the image.

Three independent observation condition modes

The TM3000 features three beam conditions to choose from depending on the information required in the image. The ‘5 kV’, ‘15 kV’ and ‘Analysis’ modes greatly simplify operating condition setup, and no adjustment is required when switching between modes.

• 5kV:          emphasizes surface detail

• 15kV:        can be used throughout the magnification range and gives the best resolution

• Analysis:  used for elemental analysis or low contrast specimens

Accelerating voltages

By providing different accelerating voltages in ‘5 kV’

and ‘15 kV’ modes, and using the high sensitivity backscattered electron detector, different types of imaging are possible with the TM3000. An accelerat- ing voltage of 15 kV is used for most imaging applica- tions and offers the best resolution. At 5 kV, the electron beam does not penetrate so far into the sample, so the images show more surface detail.

Difference in image appearance using different observation condition mode:

Directional imaging using the 4-segment detector

The TM3000 features a backscattered electron detector  with 4 independent segments. By adding or subtracting  the signals  from the segments in defferent combinations it is  possible to emphasize compositional or topographic detail in the image, as well as produce  'shadowed" image which highlight the sample from a particular direction..
