Total Station Optical System Repair Internal Lens Cleaning Service Optics Restoration for Survey Instruments
Total Station Optical System Repair & Lens Cleaning Service
The optical system is the heart of your survey instrument's measurement capability. Over time, internal optics can accumulate dust, develop fungus in humid climates, suffer coating degradation, or become misaligned from impacts and vibration. These issues degrade image clarity, reduce measurement range, and compromise accuracy. Our optical system repair service provides professional internal lens cleaning, fungus removal, coating restoration, and precision optical realignment in an ISO Class 7 clean room environment. We service total stations, theodolites, auto levels, and digital levels from all major manufacturers.
Key Features
- Internal Lens Cleaning — Professional cleaning of all internal optical surfaces including objective lens groups, focusing lens, eyepiece optics, and internal prisms
- Fungus Removal & Prevention — Chemical treatment to remove existing fungal growth on optical surfaces, followed by anti-fungal coating application to prevent recurrence
- Fog & Haze Removal — Elimination of internal fogging caused by lubricant outgassing or moisture condensation on optical surfaces
- Anti-Reflective Coating Assessment — Inspection of AR coating integrity; re-coating service available for severely degraded optics
- Optical Alignment — Precision collimation of the entire optical path — objective, focusing lens, reticle, and eyepiece — using optical bench and autocollimator
- Reticle Replacement — Replacement of damaged or faded reticles (crosshairs) with OEM-specification replacements
- Clean Room Assembly — All optical work performed in ISO Class 7 clean room to prevent dust contamination during reassembly

Frequently Asked Questions
Q: What causes fungus growth inside survey instrument optics?
A: Fungus thrives in warm, humid environments. Instruments stored in cases without desiccant, used in tropical/coastal regions, or left in vehicle trunks are at highest risk. Fungus spores land on lens coatings and grow, permanently etching the glass if left untreated.
Q: Can scratched objective lenses be repaired?
A: Minor coating scratches can sometimes be polished and recoated. Deep glass scratches typically require lens element replacement. We evaluate each case individually and recommend the most cost-effective solution.
Q: How can I prevent optical issues in my instrument?
A: Always store instruments in a dry cabinet or case with fresh desiccant. Avoid sudden temperature changes that cause internal condensation. Have optics professionally inspected during annual maintenance.
