Product detail

STM7 Microscope
The STM7 microscopes offer excellent versatility and high performance three axis measurements of parts and electrical components, with sub-micron precision. 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.

STM7-LF FEM analysis

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.

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.

 

  • 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

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.

 

Maximum Measurement Stroke 300 mm x 300 mm

Three stages are available, each with a different measurement stroke - 100 mm x 100 mm, 200 mm x 200 mm, and 300 mm x 300 mm. Whether your samples are large or small, we offer a stage that fits your application.

Broad Range of Magnifications and Working Distances

Common Problems

  • Most conventional measuring microscopes only accept a measuring objective or metallurgical objective, limiting the observation options.

STM7 Solutions

  • The STM7 meets the requirements of a wide variety of observations. It responds to your needs at both low and high magnifications, enables the measurement of uneven samples requiring ultra-long working distance objectives, and even offers a variety of observation methods.

Measuring Objectives

The objectives’ very long working distance helps you be confident when focusing on samples with large peaks and troughs and minimizes the chance that the objective comes in contact with the sample.

Furthermore, their low-magnification capability enables wide areas to be observed in a single view.

Measuring Objectives           Sample

Metallurgical Objectives

Metallurgical objectives enable high-magnification, high resolution observation comparable to that of optical microscopes.

What’s more, these objectives can be used for brightfield, darkfield, and DIC observation.

Sensor Appearance

O2 Sensor

 

1. Background

A vehicle’s overall quality is equal to the sum of its parts, and it is imperative for manufacturers to maintain rigid standards of excellence for every component. Manufacturers must also take into account requirements such as emission reduction, fuel efficiency, long-term durability, and regulatory standards. The increasing complexity of auto parts and components also requires manufacturers to place a strong emphasis on material characteristics, fitting tolerances, and technical cleanliness, which all play a strong role in the long-term durability, durability, and life-expectancy of the final product.

2. Application

O2 (oxygen concentration) sensors require higher-density and more accurate measurement than any other type of vehicular sensor. Rod-shaped ceramic heaters are inserted into tubes several millimeters wide and secured into position, and failure to position the heater accurately can result in sensor deterioration.

3. The Olympus solution

Olympus STM7 measuring microscopes are equipped with field lenses to allow an operating distance of approximately 60 to 50 millimeters, and are capable of acquiring sample visualization spanning from low-magnification, wide field imagery to high-magnification spot imagery. Dedicated calculation software provides automatic edge identification to eliminate measurement errors while offering multiple measurements to facilitate accurate mounting status digitalization.
