YANRUN YRMAT3028B Dual-Axis Electronic Autocollimator (0.5 arcsecond resolution)

Overview

The YANRUN YRMAT3028B Dual-Axis Electronic Autocollimator is a precision optical metrology instrument engineered for high-accuracy angular measurement and alignment verification in industrial metrology, optical assembly, and mechanical calibration environments. Operating on the principle of autocollimation—where a collimated beam is reflected back from a retroreflector or flat mirror and its displacement is quantified via a high-resolution imaging sensor—the YRMAT3028B delivers real-time, non-contact angular deviation data along both X and Y axes simultaneously. Its 300 mm focal length and 60 mm clear aperture support stable beam formation over extended working distances up to 28 meters, while the integrated semiconductor LED light source ensures consistent illumination with minimal thermal drift and >20,000-hour operational lifetime. Unlike traditional visual autocollimators requiring subjective eyepiece alignment, the YRMAT3028B employs an embedded digital imaging architecture with live electronic reticle display, eliminating parallax and observer-dependent error. The system’s core measurement uncertainty at center field is traceably specified as ±0.5 arcseconds under standard environmental conditions (20 ±1 °C, <50% RH), conforming to foundational principles outlined in ISO 10110-5 (optical component testing) and supporting traceable calibration against national standards.

Key Features

• Dual-axis simultaneous measurement (X and Y) enables full two-dimensional angular deviation mapping without mechanical reorientation.
• Real-time electronic eyepiece interface provides dynamic visualization of beam centroid position, crosshair alignment status, and numeric angular readout with configurable resolution down to 0.01 arcsecond.
• High-resolution CMOS detector coupled with optimized optical relay design ensures sub-pixel centroid detection stability and repeatability better than 0.1 arcsecond over 24-hour continuous operation.
• USB 2.0 host interface enables plug-and-play integration with standard industrial PCs; no external power supply required—the unit draws power exclusively via USB bus.
• Modular firmware architecture supports field-upgradable measurement modes including static alignment, stepwise scanning, and time-synchronized data capture for dynamic tilt analysis.
• Compact form factor (388 × 135 × 125 mm) and lightweight construction (<2.8 kg) facilitate deployment in constrained spaces, cleanroom environments, and mobile metrology labs.

Sample Compatibility & Compliance

The YRMAT3028B is compatible with standard optical flats (λ/20 surface quality, BK7 or fused silica), precision mirror mounts, magnetic bases, and custom retroreflective targets meeting minimum reflectivity ≥95% at 635 nm. It satisfies functional requirements for geometric error mapping per ISO 230-1 (machine tool testing) and supports compliance workflows aligned with ISO/IEC 17025:2017 (calibration laboratories). While not certified to FDA 21 CFR Part 11, its software logging mechanism includes timestamped raw image capture, operator ID tagging, and exportable audit trails in CSV and Excel-compatible formats—enabling internal GLP/GMP documentation practices. All mechanical interfaces adhere to DIN 55350-18 dimensional tolerancing conventions, and optical components are coated to MIL-C-48497A durability specifications.

Software & Data Management

The bundled YANRUN Autocollimator Control Software V2.0 runs natively on Windows 7+ (64-bit) and provides a unified GUI for instrument control, real-time visualization, and post-processing. Core capabilities include automated straightness evaluation (per ISO 230-2 Annex B), residual error curve generation with RMS/peak-to-valley reporting, and batch export to .xlsx, .csv, and .txt. Raw image frames (12-bit TIFF) and processed angular datasets are stored with metadata (date/time, serial number, user ID, environmental notes). Optional modules—including Plane Surface Analysis, Perpendicularity Deviation Mapping, and Rotary Table Harmonic Error Decomposition—extend functionality for advanced geometric metrology tasks. Software update logs and configuration snapshots are retained locally for version control and audit readiness.

Applications

• Precision alignment of optical benches, laser cavities, and interferometer reference arms in R&D and production settings.
• Verification of linear guideway straightness, spindle axis alignment, and multi-axis machine tool squareness per ASME B5.54.
• Calibration of rotary stages and air-bearing tables using multi-position indexing and harmonic error modeling.
• Assembly and adjustment of aerospace-grade optical systems (e.g., star trackers, inertial navigation sensors) where sub-arcsecond pointing stability is mission-critical.
• Education and research applications in undergraduate optics laboratories, supporting experimental validation of beam propagation theory, mirror misalignment sensitivity, and error budgeting methodologies.

FAQ

What is the maximum measurable angular range before signal saturation occurs?
The full field of view corresponds to ±1100″ (±0.3°) in both X and Y axes; beyond this, the reflected spot exits the active sensor area and triggers an out-of-range warning.
Can the YRMAT3028B be used for dynamic angular tracking?
Yes—when paired with optional high-speed acquisition firmware and external trigger synchronization, it supports frame rates up to 30 Hz for transient tilt monitoring.
Is NIST-traceable calibration documentation available?
Factory calibration certificates (with uncertainty budgets per GUM) are included; third-party NIST-traceable recalibration services are offered through authorized YANRUN metrology partners.
Does the software support automated report generation compliant with ISO 17025?
While the base software does not generate fully compliant ISO 17025 reports, it exports all required raw data and metadata fields necessary for integration into LIMS or custom report templates.
What environmental conditions are recommended for optimal accuracy?
Operation is rated for 15–25 °C ambient temperature, <50% relative humidity, and vibration isolation equivalent to ISO 230-2 Class 3; temperature gradients across the optical path should remain below 0.5 °C/m.
