LENJEX Industrial Cleaning
Gentle ultrasonic cleaning removes polishing compound, particles and fingerprints from optical components without scratching coated surfaces.
Why Ultrasonic
Optical components carry polishing compound, fine particles, pitch and fingerprints after grinding, polishing and handling. Gentle, high-frequency ultrasonic cleaning reaches curved surfaces and edges without the contact of manual wiping, which can scratch delicate coatings.
A dual-frequency cleaner or laboratory cleaner with sweep and degas is commonly used, with neutral or compatible chemistry. The work is related to cleanroom precision cleaning and semiconductor parts cleaning.
Coating compatibility and frequency must be validated with representative components before production.

Typical Workpieces
Contamination

Cleanliness Target
Acceptance is based on visual or magnified inspection for particles, haze, smears and coating integrity.
Drying must be streak-free and appropriate for coated surfaces.
Recommended Sequence
The final sequence depends on soil loading, material, rinse quality and drying behavior.
Recommended Equipment
The final specification follows process testing and production analysis.

View configurationProcess Controls
Confirm the part, soil, loading and final handling before fixing equipment settings.
Control 01
Record surfaces, cavities and features that can trap air or liquid.
Control 02
Test the heaviest representative contamination, not an ideal sample.
Control 03
Keep acoustic access and part spacing consistent with production.
Control 04
Match downstream handling to residue and corrosion risks.
System Selection
Stage count and automation follow the validated process and required output.
Batch
Compare for focused washing where rinsing and drying are managed separately.
Multi-stage
Add controlled stages when carryover and final condition matter.
Automatic
Evaluate automation when output, handling or recipe control requires it.
Acceptance
Use the same practical inspection method for trial samples and production parts.
Representative Trial
Trial evidence should cover normal production and the most difficult expected condition.
Application Questions
Include normal production parts and the most difficult expected geometry or contamination so the process is not based on an easy sample.
Provide part dimensions, material, soil, cleanliness target, parts per load, required output and available utilities.
It can if the frequency or chemistry is too aggressive. LENJEX validates coated components with representative parts to confirm gentle, non-damaging cleaning.
Higher, gentler frequencies are generally used for optical components, with sweep and degas to ensure even cavitation.
Through controlled rinsing, compatible chemistry and appropriate drying, matched to the coating and component geometry.
