LENJEX Project Record
Optics Cleaning for a Korean Manufacturer
An optics manufacturer removed polishing compound and particles with gentle sweep cleaning and streak-free drying.
LocationGyeonggi, Korea
IndustryOptical Manufacturing
EquipmentLJ-LAB30 multi-frequency cleaner
Commissioned2026
Project Context
Polishing compound on coated parts
The manufacturer finished coated lenses and windows and needed polishing compound, particles and fingerprints removed without affecting coatings.
Before LENJEX
Coatings and streaks
Coated surfaces required gentle energy, and drying had to be streak-free.
- Polishing compound and particles
- Coating integrity
- Streak-free drying
- Need for even, gentle cavitation
Cleaning Solution
Sweep cleaning with controlled drying
The LJ-LAB30 used gentle higher-frequency sweep with degas and neutral chemistry, followed by controlled streak-free drying.
Coating compatibility was validated with representative components.
Project Outcomes
Cleaning results and process improvements
Performance depends on the workpiece, contamination, chemistry, loading method and acceptance criteria.
- Result 01Polishing compound and particles removed without coating damage
- Result 02Streak-free surfaces after drying
- Result 03Even cavitation through sweep and degas
- Result 04Repeatable precision production
