Overview
The GFM PRIMOS CR Skin Fast Optical 3D Imaging System is a non-contact, high-resolution optical profilometer engineered for quantitative three-dimensional surface topography analysis of human skin in vivo. It operates on the principle of digital fringe projection—specifically, structured light illumination combined with high-speed stereo photogrammetry—to reconstruct sub-micrometer-scale surface geometry with exceptional repeatability and spatial fidelity. Unlike laser scanning or confocal approaches, PRIMOS CR employs white-light LED-based fringe projection synchronized with dual high-resolution CMOS cameras, enabling rapid acquisition (≤1 second per scan) without thermal load or phototoxicity. This makes it particularly suitable for longitudinal clinical studies, cosmetic efficacy trials, and dermatological monitoring where patient comfort, throughput, and measurement consistency are critical. The system is designed to comply with ISO 13842:2021 (optical measurement instruments for skin surface topography) and supports traceable calibration protocols aligned with DIN EN ISO/IEC 17025 requirements.
Key Features
- Sub-5 µm lateral resolution and <1 µm vertical repeatability under standardized ambient conditions (22 °C ± 2 °C, 40–60% RH)
- Full-field 3D acquisition in ≤900 ms, capturing up to 2.5 million 3D data points per frame
- Automated region-of-interest (ROI) selection with adaptive focus-locking and motion compensation algorithms
- Integrated UV-filtered illumination module optimized for epidermal contrast enhancement without melanin saturation
- Ruggedized optical bench with passive thermal stabilization and vibration-damped mounting interface
- Modular design supporting interchangeable lens configurations (10×, 20×, and 50× magnification options)
Sample Compatibility & Compliance
The PRIMOS CR is validated for in vivo imaging of facial, dorsal hand, and forearm skin sites across Fitzpatrick skin types I–VI. Its non-invasive operation eliminates sample preparation artifacts and enables repeat measurements at identical anatomical landmarks over days, weeks, or months. The system meets essential requirements of IEC 62304 (medical device software lifecycle), carries CE marking under Directive 2017/745 (MDR), and supports documentation workflows compliant with Good Clinical Practice (GCP) and ISO 22716 (cosmetic GMP). All raw 3D point cloud data are stored in vendor-neutral ASCII XYZ format with embedded metadata (timestamp, operator ID, environmental sensor logs), facilitating audit readiness for FDA 21 CFR Part 11–governed studies.
Software & Data Management
Acquisition and analysis are performed via GFM’s proprietary PRIMOS Analysis Suite v5.2, a Windows-based application validated for use in regulated environments. The software provides automated wrinkle parameterization (depth, volume, density, length), roughness quantification (Sa, Sq, Sdr per ISO 25178), and comparative statistical mapping (paired t-test, ANOVA, Bland–Altman plots). Raw data export supports CSV, STL, and OBJ formats; integration with MATLAB, Python (via open API), and electronic lab notebooks (e.g., LabArchives, Benchling) is natively supported. Audit trails record all user actions—including parameter changes, ROI edits, and report generation—with immutable timestamps and role-based access control.
Applications
- Evaluation of anti-wrinkle actives: longitudinal tracking of periorbital and glabellar wrinkle volume reduction (ISO 19779-compliant)
- Assessment of skin smoothing agents: quantification of surface texture homogenization post-treatment
- Clinical validation of acne lesion resolution: 3D volumetric change analysis of papules and pustules
- Barrier function correlative studies: correlation of TEWL measurements with microrelief parameters
- Medical device evaluation: pre- and post-intervention assessment of microneedling, RF, or fractional laser outcomes
- Regulatory dossier support: generation of objective, observer-independent endpoints for EU CPNP and US FDA submissions
FAQ
What is the minimum measurable wrinkle depth?
The system achieves a vertical repeatability of <1 µm under controlled conditions; practical detection limit for single-wrinkle depth is approximately 2.5 µm in standard acquisition mode.
Can PRIMOS CR be used on pigmented or tanned skin?
Yes—its broadband white-light illumination and polarization-sensitive camera alignment minimize specular reflection and melanin interference across Fitzpatrick types I–VI.
Is calibration traceable to national standards?
Yes—each instrument ships with a NIST-traceable step-height reference standard (Si wafer, certified step height ±0.5 nm), and annual recalibration services are available through GFM’s DAkkS-accredited laboratory.
Does the software support multi-center study synchronization?
Yes—the Analysis Suite includes centralized license management, encrypted cloud backup (GDPR-compliant), and DICOM-Skin extension support for PACS integration.
What training and technical support options are available?
GFM offers on-site installation qualification (IQ), operational qualification (OQ), and user certification programs, plus 24/7 remote diagnostics and SLA-backed hardware service contracts.
