HILGER U KERN Product Lines We Repair
Our engineers are trained on the full HILGER U KERN product range. Below are the major product families we service.
THEO Theodolites and Transit Levels
Precision angle measurement instruments used in surveying, construction layout, and infrastructure projects. Common repairs include optical barrel misalignment, eyepiece focus issues, and internal circle graduation damage from environmental exposure.
Universal Microscopes and Optical Benches
High-magnification inspection and measurement systems for quality control in automotive, aerospace, and precision manufacturing. Typical faults involve objective lens decentering, stage drive failure, and illumination system degradation.
Autocollimators and Angle Measurement Systems
Electronic and optical autocollimators for machine tool alignment, thermal testing, and optical parallelism verification. Repairs focus on collimator objective recalibration, photocell sensitivity loss, and electronic readout failures.
Electronic Control and Readout Systems
Digital encoder interfaces, electronic angle readouts, and automated measurement data acquisition for Hilger u Kern instruments. Faults include encoder signal loss, digital display malfunction, and data transmission errors.
Eyepiece and Optical Component Assemblies
Replacement eyepieces, objective lenses, prisms, and optical coatings for all Hilger u Kern instruments. Environmental damage, dust infiltration, and optical coating degradation are common wear issues in Indian climate.
Mechanical and Optical Mounts
Precision bearing assemblies, focus mechanisms, and optical element mounting hardware. Repairs involve refurbishment of worn bearings, adjustment of centering screws, and replacement of corroded mechanical parts.

Common HILGER U KERN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HILGER U KERN equipment arriving at our workshop.
- ✓Optical barrel misalignment in theodolite eyepiece assembly — Mechanical shock during transport, thermal cycling in Indian heat/monsoon, or internal bearing wear causes the eyepiece optics to decentre relative to the main barrel axis. This creates viewing distortion and parallax error.
- ✓Autocollimator objective lens decentering and focus loss — Hilger u Kern autocollimators used in thermal chamber testing or CNC machine alignment suffer optical element drift when internal mounts relax. Dust contamination in the optical path also degrades collimation quality.
- ✓Digital readout display malfunction or intermittent readings — Electronic readout modules in Hilger u Kern theodolites and levels experience capacitor aging, cold solder joints, or encoder signal loss due to vibration in industrial environments. Moisture ingress also causes intermittent display faults.
- ✓Eyepiece optical coatings degradation and reduced light transmission — Indian humid climate and environmental dust cause optical coating deterioration on Hilger u Kern eyepieces and objective lenses. This reduces image brightness and contrast, particularly in precision measurement work.
- ✓Mechanical focus drive wear and backlash in measurement microscopes — Continuous use in quality control departments, combined with fine-focusing demand on high-magnification objectives, wears Hilger u Kern focus mechanism bearings and drive screws. This introduces measurement uncertainty.
- ✓Encoder signal dropout in automated measurement systems — Hilger u Kern electronic measurement systems experience encoder wire fracture, connector corrosion, or LED photocell degradation from industrial vibration and electrical interference in Indian manufacturing facilities.
