Key Features and Benefits of Emspira 3
Designed as a 4K stand‑alone digital inspection microscope, Emspira 3 brings inspection, measurement, comparison, and data sharing together in one instrument for industrial environments.
Integrated on‑screen display (OSD) gives operators all key tools for inspection, measurement, annotation, and comparison directly on the microscope, eliminating the need for a separate PC at the workstation.
- Single system for viewing, measuring, and documenting.
- Less desk clutter and fewer device changes during shifts.
The built‑in camera delivers 4K UHD live images at up to 60 fps on an HDMI monitor, providing smooth, sharp visualization that makes small details and defects easier to detect in real time.
- Fast, fluid image for quick inspection decisions.
- High‑resolution view supports precise visual checks.
A fully coded 8:1 zoom with click‑stop positions and PlanApo 1.0× optics enables repeatable magnification and measurement, with typical measurement accuracy of ±1% at 0.75× and ±0.5% at 6.0× zoom.
- Consistent, repeatable zoom settings for routine tasks.
- High accuracy helps ensure reliable dimensional checks.
Users can measure multiple regions directly on the live image and store results together with the captured image, adding text and graphical annotations to clearly mark defects, dimensions, and areas of interest.
- Reduces manual recording errors and separate notes.
- Generates clear images ready for reports and audits.
Emspira 3 allows direct comparison of the live image with reference images or custom overlays at the push of a button, simplifying pass/fail decisions and repeated tolerance checks for similar parts.
- Helps standardize decisions between different operators.
- Ideal for recurring inspection tasks and GO/NO‑GO checks.
Images and results can be automatically stored on network folders, sent via email, or saved to USB, while barcode scanner support links images to specific samples for robust traceability.
- Makes audit‑ready records easy to maintain.
- Ensures each image can be traced back to its sample.
Eyepiece‑free operation on a large monitor enables comfortable viewing and easy collaboration, so multiple users can see the same live image and discuss findings at the same time.
- Reduces strain during long inspection sessions.
- Supports team‑based review and training.
An IP21‑rated housing with antimicrobial surface is designed for industrial environments and shared use, supporting high uptime while helping to reduce germ transmission between operators.
- Suitable for production, QC labs, and shared stations.
- Helps maintain a cleaner, safer working surface.
Applications and Usecases of Emspira 3
Emspira 3 supports digital visual inspection and documentation across multiple industries, from production and QC to R&D and training.
Use Emspira 3 at incoming, in‑process, and final inspection to visually verify parts, dimensions, and surface quality before release.
- Routine visual inspection of machined, stamped, or assembled parts.
- Pass/fail checks using live comparison against reference images.
- Capturing images with measurements for non‑conformance records.
4K imaging, zoom, and measurement capabilities are ideal for inspecting printed circuit boards, connectors, and electronic assemblies.
- Checking solder joints and fine‑pitch components at multiple magnifications.
- Comparing boards with golden samples to spot defects quickly.
- Creating annotated images for failure analysis and customer reports.
Development and quality teams can quickly examine prototypes and failed parts to understand root causes and refine designs or processes.
- Investigating cracks, wear, and contamination on critical surfaces.
- Correlating visual findings with dimensional measurements.
- Sharing images and data through the network for joint review.
The large field of view and depth of field help analyse complex mechanical parts, cutting tools, and precision metal components.
- Checking surface finish, edges, and wear on functional areas.
- Validating dimensions and fit areas using on‑screen measurement.
- Documenting inspection results for process optimisation.
Emspira 3 helps reveal surface and dimensional issues in molded housings, components, and consumer goods.
- Identifying surface defects, flash, and sink marks on molded parts.
- Verifying critical interfaces, clips, and snap‑fits.
- Recording annotated images for supplier communication and quality claims.
Eyepiece‑free viewing on a monitor supports team‑based review and operator training using live and captured images.
- Displaying inspections to groups for discussion and decisions.
- Using annotated images as visual training and reference material.
- Aligning inspection practices across operators and shifts.
