For more than a generation, UHL has been a benchmark for precision metrology and optical inspection systems, combining German engineering excellence with modular flexibility to meet the exacting needs of research and industry.
The portfolio spans manual to fully automated measuring microscopes, microhardness testers, multi-axis positioning systems, and custom-tailored inspection platforms — all designed to integrate seamlessly into modern quality control workflows.
Measuring Microscopes — From Portable to Fully Automated Systems
The UHL Measuring Microscope family ranges from compact, hand-driven microscopes for field or shop-floor inspection to motorized, fully automatic video measuring microscopes for complex dimensional analysis.
Each system features high-stability construction, precision optics, and modular configurations that support 2D and 3D measurement, pattern recognition, and image-based metrology.
Ideal for toolmakers, microfabrication engineers, and research professionals who demand repeatable, sub-micron accuracy.
Microhardness Testers VMHT — Vickers & Knoop Precision
The UHL VMHT Series microhardness testers deliver semi-automatic or fully automatic hardness testing under loads ranging from 1 g to 2 kg.
Equipped with Leica optics and a precision mechanical load system featuring fixed weights, the VMHT ensures stable, repeatable, and long-term accurate measurements of Vickers or Knoop hardness.
Applications include thin films, plated surfaces, small specimens, and material coatings — where minimal indentation and high consistency are essential.
Positioning Systems — Precision in Motion
UHL’s Positioning Systems provide high-accuracy linear stages, XY platforms, micropositioning components, and rotary or lift tables — available in open-frame or closed-frame designs.
Constructed from high-grade materials such as cast iron or granite, these systems offer excellent stability, vibration damping, and thermal consistency.
For advanced control, optional closed-loop feedback via steel or glass scales and rotary encoders can be integrated, ensuring sub-micron positional precision.
Motion can be driven by 1-, 2-, or 3-axis controllers, featuring joystick, RS232, USB, or LAN interfaces for intuitive manual or automated operation.
Custom Systems — Tailored Precision for Specialized Applications
UHL’s Custom Systems Division designs and manufactures application-specific inspection and positioning solutions, including:
-
Spinneret Inspection Microscopes — Manual, semi-, or fully automatic platforms for spinneret analysis.
-
Custom Lenses and Tube Assemblies — Built using UHL’s modular optical component system.
-
Cross (XY) and Rotary Stages — Precision motion platforms for multi-axis measurement or manipulation.
-
Micro-Assembly and Hole Punch Systems — For intricate precision engineering and manufacturing environments.
With complete in-house design, machining, assembly, and calibration, UHL ensures full control over performance, quality, and after-sales service — offering a true one-stop precision solution.
