INSIZE ISD-VMM Toolmaker Microscope — Monocular

Precision Toolmaker Microscope for Dimensional Inspection

The INSIZE ISD-VMM Toolmaker Microscope — Monocular is a precision optical measuring microscope designed for dimensional inspection of tools, dies, machined components, molds, precision parts, and other manufactured components.

Built around a rigid manual positioning system, the ISD-VMM provides controlled X/Y/Z-axis movement, optical measurement, adjustable surface and contour illumination, laser positioning, and high-resolution axis measurement.

The monocular configuration is available in four stage sizes, allowing customers to select the appropriate measuring range for their workpieces:

• ISD-VMM205D — 150 × 100 mm X/Y travel

• ISD-VMM215D — 200 × 100 mm X/Y travel

• ISD-VMM225D — 250 × 150 mm X/Y travel

• ISD-VMM235D — 300 × 200 mm X/Y travel

All four configurations provide 0.5 µm X/Y/Z resolution, 2 µm repeatability, and X/Y accuracy of ≤(3.5 + L/100) µm, where L is the measuring length in millimeters.

Key Features

Precision X/Y/Z Positioning

The ISD-VMM uses manual precision positioning across three axes for controlled dimensional inspection.

The available X/Y travel ranges from 150 × 100 mm to 300 × 200 mm, while Z-axis travel ranges from 150 mm to 200 mm, depending on the selected model.

0.5 µm Axis Resolution

The X, Y, and Z axes provide 0.5 µm resolution, giving the operator fine positioning capability when measuring small features and precision components.

2 µm Repeatability

INSIZE specifies 2 µm repeatability for the system, providing consistent positioning for repeated inspection operations.

30X Optical Magnification

The standard optical configuration uses a 3X objective, providing 30X optical magnification.

The system's published configuration also provides approximately 114X image magnification when viewed on a 19-inch monitor.

Surface & Contour Illumination

The ISD-VMM incorporates adjustable LED illumination for both:

• Surface illumination — for examining top surfaces, edges, and surface features

• Contour illumination — for viewing profiles, silhouettes, and edges

Adjustable illumination helps improve contrast when measuring different materials and component geometries.

Laser Positioning

A built-in laser positioning system helps the operator quickly identify and position the area of interest before performing detailed optical inspection.

This can reduce setup time when working with larger components or when locating specific features on the stage.

Aperture Diaphragm

The illumination system incorporates an adjustable aperture diaphragm, allowing the operator to control the illumination characteristics for different inspection conditions.

Toolmaker Microscope Measurement System

The ISD-VMM is designed around the traditional toolmaker microscope concept: precisely position the workpiece beneath an optical system and use the viewing reticle and calibrated axes to evaluate dimensional and geometric features.

The system is particularly useful for inspecting:

• Angles

• Radii

• Diameters

• Lengths

• Profiles

• Edges

• Slots

• Holes

• Tool geometries

• Mold features

• Small machined components

The optional 10X dividing eyepiece provides graduated measurement scales for optical measurement. INSIZE documentation describes horizontal and vertical scales for length measurement and diagonal scales for diameter measurement.

Available Monocular Models

The ISD-VMM monocular series is available in four configurations.

The larger models provide increased measuring travel and larger work areas for progressively larger components.

Technical Specifications

* 30X optical magnification with the standard 3X objective.
** Approximately 114X image magnification on a 19-inch monitor according to INSIZE's published configuration.

Dimensional Accuracy

INSIZE specifies X/Y-axis accuracy of:

≤(3.5 + L/100) µm

where L is the measuring length in millimeters.

The X/Y/Z axes provide 0.5 µm resolution, while repeatability is specified at 2 µm. These specifications make the ISD-VMM appropriate for dimensional inspection where controlled positioning and repeatable measurements are required.

Standard Optical Configuration

The standard optical system includes:

• Monocular viewing configuration

• 3X objective

• 30X optical magnification

• Adjustable surface illumination

• Adjustable contour illumination

• Laser positioning

• Aperture diaphragm

The optional dividing eyepiece incorporates graduated scales for optical measurement of lengths and diameters.

Auxiliary Objectives

Available auxiliary objectives include:

• 0.5X auxiliary objective — ISD-V-OB05X

• 2X auxiliary objective — ISD-V-OB2X

These allow the optical configuration to be adapted for different inspection requirements.

Probe

An optional ISD-V-PROBE is available for applications requiring probe-based inspection capability.

Computer System

A computer is optional. The microscope can be configured with computer-based viewing/documentation depending on the customer's inspection workflow.
