DSX-1000 Optical Microscope

Choose an observation mode, capture a useful image, and leave the motorized system clear and ready.

What this instrument shows

The DSX-1000 uses visible light, interchangeable objectives, controlled illumination, and a digital camera to inspect surface color, shape, texture, defects, and relief. It can capture 2D images, focus-stacked 3D data, and stitched maps.

Choose a useful mode

Goal	Start with
General inspection of a flat sample	Brightfield
Scratches, relief, or unevenness	Oblique or DIC
Edges, dust, particles, or defects	Darkfield or BF/DF mix
Crystals, fibers, minerals, or orientation contrast	Simple polarization
Large area or surface height	2D stitching or 3D acquisition

Before loading a sample

• Use only non-hazardous samples that are stable and safe to handle.
• Keep the sample under the 5 kg stage limit.
• Confirm enough clearance for the objective, head, stage, tilt, and any planned stitching or 3D motion.
• Contain liquids so they cannot spill. Ask first about sharp, fragile, wet, loose, powdery, odorous, unknown, or unusually heavy samples.

Interpret results carefully

• Record the objective, zoom, observation mode, scale, and sample orientation.
• Save the raw image or dataset before exporting reports or derived files.
• A 3D result depends on focus, reflectivity, lighting, and software assumptions.
• An optical image usually does not identify chemistry; use FTIR, Raman, or SEM-EDS when composition is the question.

What This Instrument Shows You

The Basic Idea

An optical microscope uses visible light to make small features easier to see. In the simplest case, light reflects off a sample, passes through lenses, and forms a magnified image on a camera. That is similar to what your eye does, but the microscope gives you controlled lighting, interchangeable lenses, stable focusing, digital capture, and software tools for measurement.

The DSX-1000 is a digital optical microscope, so it is especially good at turning “I can see something interesting here” into images and measurements that can be saved, compared, and shared. It can also combine many images. For example, a 3D acquisition captures images at different focus heights and keeps the sharpest parts from each height, building a view where more of the sample appears in focus. A stitched image captures neighboring regions and joins them into a larger map.

Different lighting modes can make different features stand out. Brightfield often looks the most natural. Darkfield can make edges, dust, scratches, and particles glow against a dark background. Oblique and DIC lighting can make shallow texture easier to notice. Polarized light can reveal structure in crystals, fibers, plastics, minerals, and other materials that interact with light differently depending on direction.

What Scientists Use It For

• A biologist might inspect the shape, color, and texture of a plant surface, insect part, tissue scaffold, or bio-inspired material before deciding whether higher magnification is needed.
• A mechanical engineer might look at a fracture surface, scratch, worn coating, or printed part to ask where damage started and whether the feature is wide, deep, rough, or repeating.
• A materials scientist might compare polished metals, ceramics, polymers, composites, or coatings to look for grains, pores, cracks, layers, fibers, or contamination.
• An architect, artist, designer, or conservator might examine paper, pigments, textiles, printed objects, or surface finishes to understand how something was made or why it is changing.
• A student doing an exploratory project might use the microscope as a first stop: look closely, document what is visible, then decide whether SEM, FTIR, Raman, XRD, or another instrument can answer the next question.

What To Look For In The Results

In a normal 2D image, look first for shape, color, scale, and texture. Ask: are features isolated or connected, smooth or rough, random or patterned, uniform or changing across the sample?

In a stitched image, look for larger-scale organization. A single high-magnification image may show detail, while a stitched image can show whether that detail is common across the sample or only appears in one local region.

In a 3D image or height profile, look for surface relief. A scratch, pit, bump, fiber, printed trace, or worn region may be easier to understand when you can measure height or compare cross sections instead of relying on color and shadow alone.

When comparing observation modes, look for which mode makes the question easier to answer. The “best” image is not always the prettiest image; it is the image that makes the important feature easiest to see and explain.

What This Instrument Cannot Tell You

• It usually cannot identify chemical composition by itself. If you need chemistry, consider FTIR, Raman, SEM-EDS, or another method.
• It cannot see details smaller than the limits of visible-light optics. If you need nanoscale structure, SEM may be a better tool.
• It cannot see through opaque samples unless the surface or cross section is exposed.
• 3D height measurements depend on focus, surface reflectivity, lighting, and software assumptions, so they should be treated as measurements to understand and verify, not magic truth.
• A beautiful image is not automatically a complete answer. Good microscopy still depends on sample prep, scale bars, notes, comparison images, and a clear question.

Compatible Materials And Quick Sample Prep

• Samples must be non-hazardous and safe to handle in the Breakerspace.
• Samples must weigh less than the 5 kg stage loading capacity.
• Samples must fit under the microscope head with enough clearance to focus safely.
• Liquids must be contained so they cannot spill on the stage or microscope.
• Samples should be stable on the stage and should not rest on fixed parts of the stage that prevent normal movement.
• Sharp, fragile, wet, loose, powdery, odorous, unknown, or unusually heavy samples should be discussed with staff before imaging.

If you have any questions about whether a material is appropriate to observe in the Breakerspace, please ask before bringing it to the lab.

Sample Prep

The optical microscope has few special sample-prep requirements. If a sample is non-hazardous, safe to handle, under the stage weight limit, short enough to focus on, and unlikely to contaminate the microscope, it can usually be observed.

Better sample preparation can still improve results. A clean, flat, stable sample is easier to focus, stitch, and measure. Careful cutting, mounting, or cleaning may be useful depending on the material and characterization goal.

Quick Observation Mode Selection

Detailed Operating Instructions

The sections above are meant as a quick reference for trained users. The sections below are written as a training guide for new users and include the practical details, images, and troubleshooting cues that are easiest to understand at the instrument.

The DSX-1000 has motorized stage and head movement. Before starting the software, changing objective configuration, tilting the head, or running stitched/3D acquisitions, make sure the sample and stage area have enough clearance for movement. Stop and ask staff if a sample looks like it could collide with the objective, head, stage, or fixture.

What The Optical Microscope Does

The DSX-1000 is useful for:

• Quick preview and switching between six observation modes.
• Full-color 2D image capture.
• 3D image capture and focus stacking.
• Automated 2D or 3D image stitching.
• Tilted-head imaging to observe samples from different angles.
• Rotatable-stage inspection.
• Post-processing and analysis, including annotations, distance measurements, profiles, roughness, volume estimates, and 3D mesh export.

Objectives And Magnification

Available objectives include:

• Long working distance: 3x, 10x, 20x, 40x.
• Extra long working distance: 1x, 3x, 10x.

The 3x long-working-distance objective cannot be used in polarized observation mode.

Instructions for replacing the objective unit are on page 11 of the Quick Reference Guide.

The microscope also has an internal optical zoom system that boosts magnification from 14x to 140x. Total magnification is the external objective magnification multiplied by the internal zoom factor, for an overall range of about 14x to 5600x depending on the configuration.

Observation Modes

Many observation modes are available from the desktop application or console:

The Best Image feature previews how the sample looks in each observation mode and lets you apply the preferred mode. The DSX1000 Digital Microscope Operation Manual describes Best Image on page 52 and explains the observation modes starting on page 63.

Image Acquisition

The microscope can acquire and save images in 2D or 3D, and can automatically stitch images to cover a wider field of view or create higher-resolution composite images.

2D Acquisition

A 2D acquisition saves the current live image. This is the simplest capture mode and is usually the right first step when documenting a sample or comparing observation modes. A detailed walkthrough starts on page 106 of the DSX application manual.

3D Acquisition

A 3D acquisition captures a series of images at different focal planes, composites the sharpest pixels into an image where the full selected region appears in focus, and records height data. Height data can be used for profile measurements or exported as an STL file.

Several methods are available to set the start height, stop height, and step size. The application manual describes these options starting on page 112.

Stitching

Stitching captures multiple frames while the stage travels, then combines them into a larger 2D or 3D image. Before stitching, make sure the sample is stable, the stage can move freely, and no part of the sample is catching on fixed stage components. Further information starts on page 132 of the application manual.

Other Acquisition Methods

The DSX application can also capture time-lapse sequences, movies, and images along a path. These options are described in chapter 9 of the application manual, beginning on page 106.

Data Processing And Analysis

The measurement feature can be used to extract information from captured images and 3D data, including height changes, horizontal distance, angle, profiles, roughness, and volumes of raised or depressed features.

To start a measurement workflow:

1. Open the measurement tab next to imaging.
2. Click the measurement option below the reports tab.
3. Use the profile option for distance, height, or angle between points.
4. Use the 2D-to-3D wireframe button to visualize surface shape.
5. Use the volume option to estimate the volume of a raised feature or depression.
6. Save the original image/data and export reports or derived files as needed.

For useful records:

• Record the sample name, objective, zoom level, observation mode, acquisition type, and any stitching or 3D settings.
• Save raw images or project files before exporting compressed images or reports.
• Keep notes on sample preparation and orientation if you need to compare regions later.
