A Microscope that Measures Up to
Individual Needs

Whether samples are small or large, simple or complex, or measurements are being taken by a novice or an expert, the Olympus STM7 range features measuring microscopes tailored to fit your needs.

Refined Optical Performance

The STM7 series uses the same UIS2 infinity-corrected optical system found in state-of-the-art optical microscopes.
As a result, observed images have high resolution and high contrast, with aberration thoroughly eliminated to help ensure highly accurate measurement in minute detail.

Reliable Measurements with a Stone Stage-Mounting Plate

To further improve measurement accuracy, the STM7 series uses a highly durable, vibration-resistant frame with a granite surface plate. This stability enables sub-micron level measurements with minimal error.

User-Friendly, High-Precision, 3-Axis Measurement

As modern manufacturing technology becomes increasingly miniaturized and precise, highly accurate measurements are even more essential—not only along the XY axis, but also along the Z-axis. Olympus responded by creating the first reflective active, confocal autofocus system.

• Calibration certificate issued by Olympus Corporation Test & Analysis Center, and authenticated by ILAC-MRA calibration accreditation agencies (JCSS, JAB).

• Traceability systems vary depending on periods and countries/regions. The samples used in STM7 calibrations are calibrated in each country/region. Please ask Olympus for details.

Dependable Quality Based On a Strict Traceability System

The accuracy of Olympus’ measuring microscopes is controlled by a strict traceability system, and Olympus even offers traceable calibration at the time of installation.

Common Problems

• Short measurement stroke precludes the measurement of larger samples
• Samples must be rotated because the X-axis measurement area is shorter than the Y-axis measurement area
• Due to the narrow measurement range, it is impossible to line up large numbers of samples on the stage to measure them at the same time

STM7 Solutions

• The STM7 features a 300 mm x 300 mm stage capable of measuring large samples, including 300 mm wafers and printed circuit boards.
• The X- and Y-axis measurement areas are equally long, eliminating the need to rotate samples
• Long measurement areas for both the X and Y-axis allow multiple samples to be lined up on the stage for more efficient measurement

Common Problems

• When doing visual measurement, variations can arise in the height measurements between different operators. Furthermore, this measurement method is time-consuming and inefficient

STM7 Solutions

• The STM7 focus navigation system reduces the operator subjectivity in height measurements. It also shortens the time required to perform height measurement to achieve greater efficiency

Common Problems

• Additional functions require additional operational units. Operators can’t always locate the corresponding unit quickly, which significantly reduces measurement efficiency
• Numerous operational units and their power supplies around the main unit occupy valuable working space

STM7 Solutions

• Almost all measuring microscope operations can be efficiently completed on the nearest operational unit
• The system requires only a single operational unit and power supply, regardless of how many functions are added, freeing up workspace

Manual Z-Axis Focus Models

Manual models offer excellent cost performance with familiar handle operation that enables rapid vertical movement for users who measure samples with a variety of heights.

Motorized Z-Axis Focus Models

The motorized unit improves operability and reduces handling fatigued caused by making repeated focus and height measurements. The coaxial knobs for coarse and fi ne movement offer a feeling similar to manual operation, while the models can also be equipped with an autofocus unit.

Common Problems

• Analog volume adjustment used by conventional measuring microscopes does not enable the quantitative assessment of light intensity, which can lead to variability in measured values as light intensity changes
• With conventional measuring microscopes, light intensity may need to be adjusted every time the objective is switched—making for an inefficient workflow

STM7 Solutions

• Observations and measurements can always be performed under the same conditions thanks to the microscope’s quantitative display of light intensity value
• Illumination method and light intensity are automatically adjusted to the preset value when the objective is switched, whenever the light intensity manager is used in combination with a coded revolving nosepiece

Precisely Control Light Intensity Values with a Quantitative Digital Display

The STM7 series displays light intensity using quantitative digital display, enabling observations to be made under consistent illumination conditions.

Common Problems

• The need to check the operation status of equipment, such as illumination, or measured values on individual units makes overall operation cumbersome

STM7 Solutions

• The STM7 series displays microscope status, such as illumination, together with measured values on an indicator display area, for easy checking at a glance

Fast, Visual Status Check

The indicator displays the device status and settings. The minimum X-, Y-, and Z-axis values can be switched between 0.1 μm and 1 μm, and the display units can be switched between mm, μm, inches and mil.

Detachable Digital Readout Enables Individual Preference and Placement

Whether attached to the frame or a desk, the placement of the detachable digital readout is up to the individual user. While standing to take measurements, it can be placed on the side of the frame at almost the same height as the site of observation for easy viewing. When operating from a sitting position, such as observation or measurements on a monitor using a digital camera or when using the motorized Z-axis focusing model, simply place the digital readout and hand controller on the desk.

Common Problems

• When doing visual measurement, variations can arise in the height measurements between different operators. Furthermore, this measurement method is time-consuming and inefficient

STM7 Solutions

• The STM7 focus navigation system reduces the operator subjectivity in height measurements. It also shortens the time required to perform height measurement to achieve greater efficiency

Simple, Precise Focusing System with Superior Repeatability

Olympus’ focus navigator delivers highly reproducible height measurement by projecting a pattern within the field of view and identifying vertical deviations. Slight errors can occur in height measurements taken with normal visual observation, even when focus appears to be sharp. The focus navigator, however, enables measurements to be made simply by matching up the marks, reducing operator subjectivity in measurement results.

Common Problems

• During visual measurement, the results of height measurement can vary between different operators
• Manual height measurement requires the operator to repeatedly move the stage and adjust the focus with the handle, making measurement time-consuming and inefficient
• Focusing on minute objects, such as bonding wires, is difficult

STM7 Solutions

• Using the autofocus unit, the measured value remains highly accurate regardless of the operator
• In TRACK mode, the image is automatically and continually kept in focus, enabling efficient height measurement in minimal time. The same mode renders manual focusing unnecessary for XY measurements, resulting in greater efficiency
• When a 100X objective is used, the laser spot diameter can be as small as 1 μm, permitting autofocus to be used locally, even on extremely minute objects

One-Shot Mode

Instantaneously takes autofocus from roughly focused to sharply focused at the center of the field of view.

TRACK Mode

The TRACK Mode provides autofocus that tracks the peaks and troughs of the sample, even if the stage is moved, keeping the image continually in focus. This advancement greatly improves the efficiency of Z-axis measurements by enabling observations to be made without taking your hands off the X and Y handles.

Measurement Support System

The ability to clearly and easily see the output display component of measuring microscopes is essential. Olympus measurement software deliver complex measurements with greater accuracy. The software also enables the use of digital cameras.

Coded Revolving Nosepiece

Combining a coded revolving nosepiece with a digital camera lets you display the objective magnification on-screen during observation and allows you to record that magnification. This convenient feature allows information on your sample and the objective’s magnification to be recorded at the same time when recording a sample.

STM7-FS/ Foot Switch

Enables hands-free transmission of data, allowing operators to complete measurement without taking hands off the X and Y handles.
