Core Measurement Capabilities
Each core system element addresses a practical inspection decision: optical access, image stability, surface illumination, positioning or controlled movement.
Eight-area upper lighting
Independently controlled upper-lighting areas let inspection teams select illumination around the part when surface contrast is central to the measurement task.
Laser positioning
Two laser positioning systems support repeatable part placement and help buyers prioritize alignment during dimensional inspection.
Stable image and motion control
A high-resolution SONY CMOS global-shutter camera works with an Ethernet-based dedicated motion controller for coordinated inspection operation.
EV3020 Specification Comparison
Use the model 3020 values below to screen the system against available workspace, part size, optical range and measurement repeatability requirements.
| Model | 3020 |
|---|---|
| Measuring range | 300 × 200 × 200 mm |
| Overall dimension | 1200 × 720 × 1600 mm |
| Work table glass | 339 × 239 × 10 mm |
| Weight | 280 kg |
| Maximum table load | 20 kg |
| Measurement accuracy | 1.5 + L/200 μm |
| Repeatability | 0.002 mm |
| Optical magnification | 0.7–4.5X |
| Image magnification | 20–125X |
| Axis display resolution | 0.00001 mm (0.01 μm) |
| Operation model | XY axis manual, Z axis automatic |
Selection point: The 300 × 200 × 200 mm range and 20 kg maximum table load give procurement teams clear starting criteria for part envelope and fixture planning.
Manufacturing and Quality Foundation
The EV3020 architecture connects scale feedback, motion control and reporting so QC teams can review dimensional results in familiar business and engineering formats.
Absolute X/Y/Z linear scalesEasson-developed absolute linear scales provide resolution up to 0.01 micron across the three axes.
Manual XY and automatic Z operationThis operating model helps buyers match part positioning and vertical movement to their inspection routine.
Ethernet motion controllerThe dedicated controller provides the motion-control foundation for the visual measuring workflow.
Flexible result exportMeasurement software can export results to DXF, Word, Excel, PDF and other formats.
2D and 3D measurement optionWhen used with a UK Renishaw high-precision touch probe, the system supports 2D and 3D multiple measurement.
Application Fit and Buyer Decisions
Match the inspection environment to a concrete system characteristic before requesting a configuration or commercial quotation.
Mobile phone and electronics
Small, detailed components benefit from 20–125X image magnification and automatic focus. Choose this route when feature visibility and non-contact inspection are priorities.
PCB and micro-components
The SONY CMOS global-shutter camera and independently controlled eight-area light source support image-led inspection. Prioritize lighting flexibility when contrast varies across the part.
Molds and metals
The 300 × 200 × 200 mm measuring range and 20 kg maximum table load establish an initial fit check. Confirm part envelope, fixture plan and load before ordering.
Plastic inspection
Non-contact optical measurement helps teams assess dimensional features without relying on physical contact for every inspection step. Review the accuracy requirement against 1.5 + L/200 μm.
Dimensional QC reporting
DXF, Word, Excel and PDF export supports teams that need results to move into engineering, quality or customer documentation workflows.
2D and 3D checks
Buyers requiring probe-enabled dimensional work can assess the Renishaw touch-probe option for 2D and 3D multiple measurement.
