Why Milliscope HDX
Inspect Where Access Is the Problem
Steer Toward the Target
Two-way +/-170° articulation lets the inspector redirect the distal tip instead of relying solely on shaft positioning.
Navigate Restricted Areas
Shape memory metal outer sheathing provides a durable probe structure intended for demanding inspection environments.
Control Difficult Images
Adjustable LED illumination plus selectable automatic and manual exposure gives inspectors more control over changing internal viewing conditions.
Document the Inspection
Capture still images and video directly to USB storage for inspection records, review and communication.
Use One Scope Platform
The Milliscope HD base unit supports HDX probes alongside HDV videoscopes and the fiberscope camera handle.
Technical details
Everything You Need Before You Decide
The Milliscope HDX is a small-diameter articulating micro videoscope for remote visual inspection of restricted internal areas. Available in 1.1 mm and 1.6 mm probe diameters, it combines a miniature 160,000-pixel CMOS image sensor with high-performance optics for visualization through exceptionally small access points.
Two-way +/-170° up/down articulation allows the distal tip to be redirected after insertion instead of relying only on probe position. Shaft lengths range from 150 mm to 1.0 m, with viewing directions from 0° to 90° depending on the selected probe configuration.
Choose the Setup That Fits the Inspection
- Select 1.1 mm or 1.6 mm for the available access.
- Match shaft length to the required inspection reach.
- Select the viewing direction for the target location.
- Account for bends and restrictions along the access path.
- Confirm the 1-50 mm depth of focus suits the target.
- Discuss a custom HDX when standard options do not fit.
Control the Image
Adjustable LED illumination, automatic or manual exposure, and 90° image rotation help adapt the view as internal geometry and lighting conditions change.
Capture Your Findings
Push-button image and video recording to USB storage lets inspectors retain visual evidence for review, documentation, and communication after the inspection.

Which Scope Technology Fits the Inspection?
The right choice depends on what limits the inspection: access size, required reach, digital imaging, or the need to redirect the probe after insertion.
Choose HDF When
Access Is Extremely Small
Start with HDF when the smallest possible diameter, fiber-based inspection, flexible or semi-rigid construction, or a very broad length range drives the selection.
Choose HDV When
You Need CMOS Imaging
Use HDV when a small digital videoscope can reach the target directly and an articulating distal tip is not required for the inspection path.
Choose HDX When
The View Must Turn
Choose HDX when restricted access must be combined with controlled tip articulation to redirect the view toward an internal feature after insertion.
Diameter alone does not determine the correct Milliscope configuration. AIT can review the minimum opening, required reach, inspection path, target position, viewing direction, and inspection objective before the final HDF, HDV, or HDX configuration is selected.
Got questions?
Before You Specify the HDX
Will the 1.1 mm HDX replace a larger videoscope?
Not necessarily. The HDX is valuable when access size prevents a larger articulating probe from reaching the inspection area. Larger-diameter scopes can be preferable when the access path allows them, particularly when greater illumination or other capabilities are needed. Small-diameter videoscopes are specialized inspection tools rather than universal replacements for larger probes.
When should I choose the 1.1 mm probe instead of the 1.6 mm?
Choose based on the entire access path, not simply the entry hole. Consider the smallest restriction, bends, required reach and clearance needed to articulate near the target. If both diameters physically fit, send AIT the component geometry and inspection objective so the complete configuration can be evaluated rather than choosing on diameter alone.
Can the HDX look around a bend after entering the component?
The two-way +/-170° steerable tip is designed to redirect the view after insertion. This can be useful for following curved geometry, bringing a sidewall or feature into view, and inspecting targets that are not directly in line with the access opening.
Is the HDX a better choice than a fiberscope for very small access?
That depends on the inspection. One important difference is that the HDX places a miniature CMOS imaging sensor in an extremely small articulating probe. Industry reporting notes that earlier ultra-small inspection approaches often relied on fiber optics with substantially lower pixel counts and without comparable articulation.
Can I use my existing Milliscope HD base unit with an HDX probe?
The HDX is part of the Milliscope HD platform. The published system information says the base unit accommodates HDX probes as well as HDV videoscopes and a fiberscope camera handle. For an existing system, AIT should confirm the exact base-unit configuration before ordering an additional probe.
Can the HDX be configured for an inspection that does not fit a standard probe?
Custom configuration is part of the HDX product offering. If the standard diameter, length or viewing arrangement does not match the inspection, provide AIT with the component geometry and inspection requirements so the feasibility of a custom configuration can be evaluated.
What information should I send AIT before requesting an HDX quote?
Send the minimum access diameter, required insertion distance, internal path or bends, location of the inspection target, desired viewing direction and what you need to see or document. A drawing, component photo or inspection-path dimensions can help AIT evaluate which probe configuration fits the application.
What happens if my access opening is even smaller than 1.1 mm?
Don't force the application into the HDX simply because it is the product being viewed. Other micro-inspection technologies exist below 1.1 mm, including non-articulating video and fiber-based solutions. AIT should evaluate the required access, steering and image requirements to determine the more appropriate inspection technology. Industry offerings demonstrate that sub-1 mm visual inspection is possible, but capabilities differ significantly by technology.
