What it is

General reference — not yet source-verified

The Zeiss Axio is an optical microscope used for metrology and inspection work. Optical microscopes in this class are used to observe sample surfaces, document features, and support visual examination during research and fabrication workflows.

How it works

General reference — not yet source-verified

Optical microscopes in this class form magnified images with objective lenses and transmitted or reflected illumination. Metrology and inspection use commonly relies on direct viewing and digital image capture to examine surface condition, pattern quality, alignment features, and defects without contacting the sample.

Where it fits in the process flow

General reference — not yet source-verified

Microscopes of this class fit throughout fabrication and laboratory flows wherever visual verification is needed between process steps. Optical inspection commonly appears after patterning, deposition, etch, cleaning, packaging preparation, and other handling stages to check whether a sample is ready for the next operation or for more detailed characterization.

Applications

General reference — not yet source-verified

Optical microscopes in this class are used for general sample inspection, visual metrology support, and image documentation. Typical use includes checking patterned features, surface contamination, edge condition, coating uniformity, and other visible attributes on fabricated or prepared samples.

Frequently asked questions

What kinds of samples can this class of optical microscope inspect?General reference — not yet source-verified

Such systems can inspect a wide range of samples that are compatible with optical microscopy, including machined metal parts, electronic components, printed circuit boards, wafers, glass, ceramics, polymers, and prepared metallographic specimens. Both opaque and transparent samples can be examined by selecting the appropriate illumination mode.

What types of measurements are possible with this class of system?General reference — not yet source-verified

Typical measurements include lengths, widths, diameters, angles, radii, area, and center-to-center distances of features visible in the optical image. With focus-based techniques, height differences and surface profiles can also be characterized, though the depth range is limited compared to stylus or optical profiler systems.

How does the system achieve accurate measurements?General reference — not yet source-verified

Accuracy is established through calibration using a known reference artifact, such as a stage micrometer or calibrated scale. Measurement software converts the pixel dimensions of the camera image into real units based on the current objective magnification and calibration data, so consistent calibration is essential for reliable results.

Is automation available for inspection workflows?General reference — not yet source-verified

Instruments in this class range from fully manual to highly automated. Automated versions typically include motorized focusing, motorized stages for sample movement, and software routines for autofocus, image stitching, and repetitive measurement, which improve repeatability and allow larger areas to be inspected systematically.
