INSIZE ISM-DL520 Motorized Focus Stacking Microscope with Display

Automated Focus Stacking for High-Detail Inspection and Measurement

The INSIZE ISM-DL520 Motorized Focus Stacking Microscope is a digital inspection and measurement system designed for applications where conventional microscopes can struggle to maintain focus across components with significant height variation or complex three-dimensional surfaces.

The ISM-DL520 combines a 2-megapixel 1/2" CMOS sensor, 1920 × 1080 Full HD imaging, built-in measurement software, motorized focus movement, and automated focus stacking into a self-contained microscope system that operates without requiring a separate computer.

During focus stacking, the motorized mechanism moves the camera through a programmed vertical range and captures multiple images at defined positions. The system then combines those images into a clear composite image with an expanded depth of field. This makes it particularly useful for inspecting parts where the top and bottom surfaces cannot be kept simultaneously in focus with conventional optical focusing.

Key Features

Motorized Focus Stacking

The ISM-DL520 automates the process of capturing multiple focal planes.

The operator establishes the upper and lower focus positions, then specifies the number of stops, dwell time, and motor speed. The system automatically moves through the programmed range, captures images, and synthesizes them into a clear image covering the required depth.

Up to 70 mm Motorized Travel

The motorized focus-stacking mechanism provides a maximum travel distance of 70 mm, allowing the system to accommodate workpieces with substantial height variation during automated image acquisition.

24.5X–204.5X Image Magnification

The standard configuration provides image magnification from approximately 24.5X to 204.5X, giving users a broad range for both general inspection and high-detail examination.

INSIZE's published documentation also provides objective-specific accuracy and magnification data, allowing the system to be configured around the measurement requirements of the application.

Built-In Measurement Software

The ISM-DL520 incorporates measurement software directly into the microscope system, eliminating the need for a separate computer for normal operation.

Measurements can be performed directly on the displayed image, with results exportable to Excel for documentation and further analysis.

1080P High-Definition Imaging

The integrated 2-megapixel 1/2" CMOS sensor produces 1920 × 1080 resolution, providing a clear digital image for inspection, documentation, and measurement.

Standalone Operation

The system's built-in software can be operated using the supplied mouse, allowing the microscope to function as a self-contained inspection station rather than requiring a separate PC and software installation.

Automatic White Balance & Exposure

Automatic white balance and exposure help maintain consistent image quality as lighting and workpiece conditions change.

USB Image Storage

Images can be captured and saved to the included USB flash drive, making it easy to document inspection results and transfer images for reports or records.

Objective Magnification & Measurement Accuracy

One of the most important specifications of the ISM-DL520 is that its measurement accuracy varies according to the selected objective and resulting image magnification.

INSIZE's current documentation lists this objective-specific measurement performance.

Important: The CRB product title currently emphasizes 24.5X–204.5X, while INSIZE's current PDF also documents objective/image-magnification combinations extending from 14.7X through 204.5X. The exact configuration supplied should therefore be confirmed when ordering.

Automated Focus-Stacking Workflow

The motorized focus-stacking system is designed to simplify inspection of components with substantial depth or uneven surfaces.

1. Set the Upper Focus Position

The camera is moved to the highest surface requiring inspection and the upper focus position is established.

2. Set the Lower Focus Position

The motorized mechanism moves through the required range and the lower focus position is established.

3. Configure the Stack

The operator specifies:

• Number of stops

• Dwell time at each stop

• Motor travel speed

4. Run the Automated Sequence

The microscope automatically moves through the programmed range and captures images at the specified positions.

5. Generate the Composite Image

The captured images are synthesized to produce a clear image covering the selected depth range.

This automated process can significantly reduce the manual focusing required when inspecting three-dimensional components.

Measurement & Inspection Applications

The ISM-DL520 is particularly well suited for:

• Precision component inspection

Ideal Industries

The system is suited for professional inspection environments including:

• CNC machining

• Precision manufacturing

• Tool and die manufacturing

• Aerospace

• Automotive

• Electronics

• Medical device manufacturing

• Metalworking

• Mold and tooling

• Industrial equipment

• Research laboratories

• Quality assurance and metrology

Digital Imaging & Documentation

The ISM-DL520 is designed not only for visual inspection but also for creating digital inspection records.

Users can:

• Capture high-definition images

• Store images to USB

• Perform measurements on-screen

• Export measurement results to Excel

• Use automated focus stacking for increased depth of field

• Document inspection results digitally

This makes the microscope useful in environments where inspection results need to be communicated, archived, or incorporated into quality documentation.

Technical Specifications

The CRB Supply listing confirms the core digital imaging and standalone software specifications, while INSIZE's instruction manual provides the motorized focus-stacking parameters.

Standard Equipment

The INSIZE documentation lists the following standard delivery items:

INSIZE's documentation identifies an X-Y metal stage with 100 × 86 mm travel as an optional accessory.

Optional X-Y Metal Stage

For applications requiring controlled lateral positioning of the workpiece, the optional ISM-DL-STAGE1 X-Y metal stage provides:

• X-Y positioning

• 100 × 86 mm travel

• More controlled specimen positioning during measurement and inspection

This can be particularly useful when repeatable positioning is important for dimensional inspection.

Why Choose the INSIZE ISM-DL520?

The ISM-DL520 combines several functions that would otherwise require separate equipment or manual processes:

• High-magnification digital inspection

• Full HD imaging

• Built-in measurement software

• Automated motorized focus stacking

• Up to 70 mm focus travel

• Programmable image-acquisition sequence

• Digital image capture

• USB data storage

• Excel measurement export

• Automatic exposure and white balance

• No separate computer required for normal operation

For manufacturers inspecting three-dimensional components, the motorized focus-stacking capability is the primary differentiator. Instead of manually adjusting focus and attempting to document multiple focal planes, the system can automatically capture and combine images across a programmed vertical range.
