Leica Ivesta 3 Greenough Stereo Microscope

Overview

The Leica Ivesta 3 Greenough Stereo Microscope is an ergonomically engineered optical instrument designed for high-throughput visual inspection, quality control, and rework applications in industrial manufacturing, electronics assembly, precision mechanics, and academic teaching laboratories. Based on the classical Greenough optical design—featuring two separate, angled optical paths that converge to deliver true stereoscopic depth perception—the Ivesta 3 delivers natural 3D visualization without compromise. Its core innovation lies in Leica’s proprietary FusionOptics technology, which simultaneously optimizes resolution and depth of field across the entire magnification range—a departure from conventional trade-offs between sharpness and focus volume. This enables users to observe fine structural details while maintaining contextual spatial awareness, significantly reducing the need for repeated refocusing during dynamic inspection workflows.

Key Features

• FusionOptics optical system delivering up to 3× greater depth of field at full resolution compared to standard Greenough configurations
• 9:1 zoom ratio (typically 6.3×–56× with 10× eyepieces), supporting seamless transition from macro overview to micro-detail assessment
• Maximum magnification of 55× with apochromatically corrected optics ensuring chromatic and spherical aberration correction
• Working distance up to 122 mm—optimized for hands-on manipulation, tool-assisted dissection, soldering, or component handling under observation
• Encoded zoom mechanism automatically records magnification and zoom position metadata alongside captured images
• Integrated 12-megapixel CMOS camera option with real-time streaming at up to 60 fps and adaptive auto-exposure for consistent imaging across varying sample reflectivity
• C-mount interface variant available for flexible integration with third-party digital imaging systems or machine vision platforms

Sample Compatibility & Compliance

The Ivesta 3 accommodates a broad spectrum of opaque, reflective, and semi-transparent specimens—including PCBs, machined metal parts, biological tissue sections, solder joints, and polymer components—without requiring specialized preparation. Its long working distance and unobstructed optical path support compatibility with standard industrial fixtures, vacuum chucks, and micromanipulators. The system complies with ISO 10934-1 (optical microscopy—nomenclature and definitions) and conforms to CE marking requirements under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. When used in regulated environments (e.g., ISO 13485-certified medical device manufacturing or IATF 16949 automotive QA labs), the encoded zoom and Enersight software support audit-ready documentation per GLP/GMP principles, including timestamped image metadata and user-accessible configuration logs.

Software & Data Management

All camera-equipped variants operate exclusively via the Leica Enersight software platform—a unified, cross-device application supporting Windows, macOS, and web-based access through compatible browsers. Enersight provides intuitive touchscreen- and keyboard-driven control of illumination, focus, zoom, and capture parameters. It enables annotation, side-by-side image comparison, calibrated 2D measurement (length, angle, area), and export in TIFF, JPEG, PNG, or lossless DICOM-compliant formats. Image metadata—including magnification, objective ID, exposure time, white balance settings, and operator ID—is embedded in EXIF headers and retained in exported files. For enterprise deployment, Enersight supports networked storage mapping, role-based user permissions, and optional integration with LIMS or MES systems via configurable API endpoints.

Applications

• Electronics manufacturing: Solder joint inspection, component placement verification, counterfeit detection, and post-reflow defect analysis
• Precision engineering: Surface finish evaluation, burr identification, thread inspection, and dimensional spot-checking
• Academic instruction: Comparative morphology studies, dissection guidance, and materials science demonstrations
• Quality assurance labs: Incoming goods inspection, in-process checks, and final product release verification per internal SOPs
• Rework stations: Real-time guided repair of micro-assemblies, wire bonding, and adhesive dispensing validation

FAQ

Is the Ivesta 3 compliant with FDA 21 CFR Part 11 for electronic records in regulated industries?
The Ivesta 3 itself is not a standalone Part 11–compliant system; however, when deployed with Enersight software configured with audit trail logging, electronic signatures, and secure user authentication (via optional LDAP/Active Directory integration), it may be validated as part of a broader compliant workflow.
Can the working distance be extended beyond 122 mm with auxiliary lenses?
No—working distance is fixed by the optical tube design and objective lens focal geometry. Auxiliary lenses (e.g., telecentric or wide-field adapters) may alter magnification and FOV but do not increase physical working distance.
Does the encoded zoom retain calibration after power cycling?
Yes—zoom position encoding is hardware-based and non-volatile; calibration persists across system restarts and does not require periodic recalibration.
What illumination options are supported?
Standard models include LED ring light with adjustable intensity and color temperature (5,600 K); optional fiber-optic cold-light sources and polarized illumination modules are available for glare-sensitive or birefringent samples.
Is remote operation supported over LAN or Wi-Fi?
Enersight supports local network streaming and remote desktop control via standard RDP/VNC protocols; native wireless operation is not supported due to latency and bandwidth constraints for real-time 60 fps video transmission.
