Inside DADI Factory - Part 1: How Optical Lenses Are Cleaned Before Surveying Instrument Assembly
30-second answer: Before optical components enter surveying instrument assembly, DADI technicians clean and inspect the lens surfaces to reduce dust, residue and handling marks. This gives the optical assembly process a cleaner and more controlled starting point.
How Are Optical Lenses Cleaned Before Surveying Instrument Assembly?
Before an optical component is installed, the technician handles the lens with a soft lint-free cloth and applies a controlled amount of cleaning solution. The lens is then checked for visible dust, streaks or residue before moving to the next assembly step.

Why Does Optical Cleaning Matter?
Optical surfaces are sensitive to contamination. Dust, fingerprints, lint or cleaning residue can reduce visual clarity and create avoidable variation during optical alignment. Cleaning the component before assembly gives the technician a more controlled starting point for later inspection and alignment.
Reduce visible dust, lint, fingerprints and residue before assembly.
Check the optical surface before the component enters the instrument assembly process.
Use a repeatable handling and cleaning step as part of the optical assembly workflow.
Which Surveying Instruments Use These Optical Components?
This type of optical preparation is relevant to surveying instruments that rely on a clear and correctly assembled optical path, including total stations and electronic theodolites. Optical cleaning is one step in the broader manufacturing and inspection process.
What Does This Factory Image Show?
The image documents a manual optical-cleaning step inside DADI's production process: an optical component is handled with a soft cloth and cleaning liquid before assembly. This provides direct process evidence of how optical components are prepared at the workbench.
Frequently Asked Questions
Why are optical lenses cleaned before surveying instrument assembly?
The cleaning step is used to remove visible contamination such as dust, lint, fingerprints and residue before the optical component is installed.
Which DADI instruments use optical components prepared this way?
DADI manufactures surveying instruments including total stations and electronic theodolites, both of which rely on optical assemblies as part of their measurement systems.
Is lens cleaning the final quality inspection?
No. Optical cleaning is a pre-assembly process step. Final instrument quality also depends on subsequent optical alignment, assembly, calibration and inspection procedures.
