Industrial Endoscope Inspection for Narrow & Inaccessible Spaces

Inspect small holes, narrow passages, precision components, and internal structures with Shodensha ultra-thin industrial endoscopes with probe diameters from 1.8 mm down to 0.8 mm.

Start with the available opening diameter, required insertion depth, viewing direction, and working distance. The current lineup includes fixed-tip, articulating, sub-1 mm, close-range, and longer-reach configurations.

FIND YOUR INSPECTION APPROACH

What limits your internal inspection?

Choose based on opening diameter, whether directional tip control is required, and how close the probe must focus to the target.

Selected inspection requirement Ultra-Thin Inspection

Small holes and restricted internal access

Ultra-Thin Internal Inspection

Use a small-diameter industrial endoscope when the inspection opening is too restricted for a conventional probe. Shodensha offers fixed-tip 1.8 mm and 1.2 mm configurations for internal visual inspection in narrow and difficult-to-access spaces.

Typical inspection requirements

  • Small holes and restricted openings
  • Narrow internal passages
  • Precision components and compact assemblies
  • Equipment areas that cannot be viewed directly

Typical inspection requirements

  • Inspection targets located away from the insertion axis
  • Internal structures requiring directional viewing
  • Restricted spaces where repositioning the complete probe is difficult
  • Applications requiring a 1.8 mm articulating probe

Industrial Endoscope Selection

Select the Probe from the Actual Inspection Geometry

The smallest probe is not automatically the best choice. Confirm the opening diameter, required insertion depth, working distance, viewing direction, and whether probe-tip articulation is required before selecting the model.

  1. 1. Confirm the Opening Diameter Select a probe diameter that can pass through the available opening. The Denkei Shodensha lineup currently spans 1.8 mm, 1.2 mm, 0.85 mm, and 0.8 mm probe diameters.
  2. 2. Define the Required Reach Confirm how far the probe must travel from the access point to the inspection target. The MIVS-1805TP, MIVS-1805TPA2, MIVS-1205TP, and MIVS-08505TP are specified with 0.5 m probe lengths, while the MIVS-08010TP is specified at 1.0 m.
  3. 3. Determine the Viewing Direction Use a fixed-tip model when the target can be viewed along the probe direction. Choose the MIVS-1805TPA2 when two-direction tip articulation is required after insertion.
  4. 4. Confirm the Working Distance For extremely close targets, the MIVS-08505TP offers a 0.5–3 mm close-range focus configuration. A separate 3–70 mm standard focus configuration is also available.

Internal visual inspection

Industrial Endoscope Inspection for Small Holes and Confined Spaces

Ultra-thin industrial endoscopes provide visual access to internal areas that cannot be observed directly. The appropriate probe depends on the available opening, required insertion depth, viewing direction, and distance between the probe tip and the inspection target.

Small Hole Inspection

Use small-diameter probes to inspect internal surfaces through restricted openings where larger endoscopes cannot be inserted.

Precision Component Inspection

Observe internal areas of compact mechanical components, precision parts, and assemblies with limited direct access.

Directional Internal Inspection

The MIVS-1805TPA2 provides two-direction tip articulation when the inspection target is not aligned with the insertion direction.

Ultra-Close Inspection

The MIVS-08505TP close-range configuration provides an observation depth of 0.5–3 mm when the inspection target is positioned extremely close to the probe tip.

How to select

How to Select an Ultra-Thin Industrial Endoscope

Start from the physical inspection requirement rather than from camera diameter alone. Confirm the access opening, insertion depth, required viewing direction, and working distance before selecting the probe.

Selection Factor What to Confirm Shodensha Options
Opening Diameter Minimum available access diameter 1.8 mm, 1.2 mm, 0.85 mm, and 0.8 mm probe options
Insertion Depth Distance from the opening to the inspection point 0.5 m on MIVS-1805TP, MIVS-1805TPA2, MIVS-1205TP and MIVS-08505TP; 1.0 m on MIVS-08010TP
Viewing Direction Whether the target is aligned with the insertion axis Fixed-tip models or two-direction articulating MIVS-1805TPA2
Working Distance Distance from the probe tip to the target surface MIVS-08505TP offers 0.5–3 mm close-range and 3–70 mm standard focus configurations

MIVS probe system

Detachable Camera Cable Units for Different Inspection Requirements

Shodensha states that the endoscope main unit and camera cable unit can be separated. After purchasing an MIVS system, compatible camera cable units can be added to use different probe diameters or configurations with the main unit.

Change Probe Diameter

Camera cable units are offered in multiple diameters, allowing the probe configuration to be adapted to different access openings.

Replace the Probe Independently

The detachable design allows the camera cable unit to be replaced independently rather than requiring replacement of the complete endoscope system.

Frequently asked questions

Industrial Endoscope Selection FAQ

What probe diameter should I choose?

Start with the smallest physical opening the endoscope must pass through. The current Denkei Shodensha lineup includes 1.8 mm, 1.2 mm, 0.85 mm, and 0.8 mm probe diameters.

When should I use an articulating endoscope?

Use the MIVS-1805TPA2 when the target cannot be viewed directly along the insertion axis. Its 1.8 mm probe tip can be moved in two directions using the lever on the main unit.

Which model is suitable for very close inspection?

The MIVS-08505TP is available with a 0.5–3 mm close-range focus specification for targets positioned extremely close to the probe tip. A 3–70 mm standard focus configuration is also available.

Which model has the smallest probe?

The MIVS-08010TP uses a 0.8 mm probe and is the smallest diameter in the current Shodensha lineup offered by Denkei Americas.

Can different probe diameters be used with the MIVS main unit?

Shodensha states that the main unit and camera cable unit are detachable and that additional compatible camera cable units can be purchased to use different probe diameters.

What information should I provide when requesting a recommendation?

Provide the opening diameter, required insertion depth, approximate distance from the probe tip to the inspection surface, whether directional tip control is required, and a description of the component or internal area being inspected.
