ASH Technologies AI100-064 +50 Industrial Inspection Objective Lens

Overview

The ASH Technologies AI100-064 +50 is a high-performance industrial objective lens engineered for precision optical inspection and dimensional metrology in automated visual inspection systems. Designed and manufactured in Ireland, this fixed-focal-length objective integrates into ASH’s proprietary OMNI3 and INSPEX3 digital microscopy platforms—both purpose-built for non-contact surface analysis, defect detection, and quantitative measurement in electronics manufacturing, PCB assembly, semiconductor packaging, and precision mechanical component QA/QC workflows. Unlike standard microscope objectives optimized for biological or metallurgical applications, the AI100-064 +50 adheres to telecentric optical design principles with calibrated magnification stability across its working distance range, ensuring sub-pixel spatial fidelity required for traceable measurement. Its +50 designation denotes a specific optical correction grade optimized for high-contrast edge detection at extended working distances, enabling consistent focus over variable sample topographies without refocusing—critical for inline production-line integration.

Key Features

• Optical magnification up to 662× with digital interpolation extending effective resolution to 1324× under controlled illumination and sensor alignment
• Telecentric optical path architecture minimizing perspective distortion and parallax error—essential for accurate length, area, and feature-spacing measurements
• Dedicated mechanical interface and electrical handshake protocol for seamless integration with ASH OMNI3 metrology-grade platform (supports calibration traceability per ISO 17025)
• INSPEX3-compatible configuration limited to qualitative inspection mode; disables measurement firmware pathways to comply with system-level validation boundaries
• Multi-layer anti-reflective coating optimized for 400–900 nm spectral range, enhancing contrast on reflective substrates (e.g., solder paste, gold-plated contacts, silicon wafers)
• Robust aluminum-alloy housing rated IP52 for resistance to particulate ingress and incidental solvent exposure in cleanroom-adjacent environments

Sample Compatibility & Compliance

The AI100-064 +50 supports flat, semi-reflective, and moderately textured samples with height variations ≤ ±1.2 mm within its depth-of-field envelope. It is routinely deployed for inspecting printed circuit board solder joints (IPC-A-610 Class 2/3), wire bond integrity, micro-connector pin coplanarity, and thin-film coating uniformity. The lens complies with CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage directive (2014/35/EU). When used within the OMNI3 platform, full measurement workflows align with ISO 10360-8 (coordinate measuring systems) and support audit-ready documentation for GLP and ISO 9001 quality management systems. No FDA 21 CFR Part 11 compliance is applicable, as the lens itself does not perform data acquisition or storage—this responsibility resides with the host platform’s software architecture.

Software & Data Management

Lens operation is fully managed through ASH’s proprietary OMNI3 Control Suite (v4.2+) and INSPEX3 Vision Manager (v3.8+), both running on Windows 10 IoT Enterprise LTSB. The AI100-064 +50 exposes calibrated pixel-to-micron mapping parameters via standardized GenICam XML descriptors, enabling third-party machine vision SDKs (e.g., Halcon, OpenCV with GenTL) to ingest geometric scaling metadata directly. Measurement reports generated by OMNI3 include embedded lens serial number, calibration timestamp, and uncertainty budget per GUM (Guide to the Expression of Uncertainty in Measurement). Audit trails record all user-initiated focus adjustments, magnification changes, and measurement annotations—retained for ≥36 months in accordance with internal QA retention policies.

Applications

• Automated optical inspection (AOI) of fine-pitch QFN and BGA packages prior to reflow
• Quantitative assessment of solder paste volume and stencil aperture fill ratio (IPC-7525)
• Edge detection and chamfer verification on medical device machined components
• Non-destructive evaluation of conformal coating coverage and bubble entrapment
• Post-assembly verification of flex circuit trace width and spacing tolerances (IPC-2221)
• Surface defect classification (scratches, pits, discoloration) using supervised CNN models trained on ASH-curated image datasets

FAQ

Can the AI100-064 +50 be used with non-ASH imaging platforms?
No—it requires ASH-specific mechanical mounting geometry, electrical synchronization signals, and firmware-level calibration tables. Integration with third-party systems is not supported.
Does the +50 designation indicate focal length or magnification?
Neither. It refers to ASH’s internal optical correction grade for extended working distance stability and chromatic aberration suppression across the visible-NIR spectrum.
Is recalibration required after lens replacement?
Yes. Each AI100-064 +50 unit ships with a unique calibration certificate. Replacement necessitates re-execution of the OMNI3 system-level calibration routine using NIST-traceable step gauges.
What is the maximum usable working distance?
38.5 mm ±0.3 mm for OMNI3 configurations; 42.0 mm ±0.4 mm for INSPEX3 configurations—both values defined at optimal focus position under 590 nm LED illumination.
Is the lens compatible with UV or deep-UV illumination sources?
No. The multi-layer AR coating is optimized for 400–900 nm. Exposure to wavelengths below 380 nm may degrade coating performance and induce fluorescence artifacts.
