Precision optical components being cleaned

LENJEX Industrial Cleaning

Optics & Lenses Ultrasonic Cleaning

Gentle ultrasonic cleaning removes polishing compound, particles and fingerprints from optical components without scratching coated surfaces.

Why Ultrasonic

Ultrasonic cleaning for Optics & Lenses

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.

Optical cleaning accessories and baskets
  • Removes polishing compound and fine particles
  • Gentle, non-contact cleaning for coated surfaces
  • Higher frequencies protect delicate optics
  • Sweep and degas for even cavitation
  • Repeatable cleaning for precision production

Cleanliness Target

Define clean before choosing equipment

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

A process route for evaluation

The final sequence depends on soil loading, material, rinse quality and drying behavior.

  1. Step 1Validate coating compatibility and frequency
  2. Step 2Gentle ultrasonic wash to remove polish and particles
  3. Step 3Careful rinse stages
  4. Step 4Streak-free drying and controlled handling
  5. VerifyInspect for haze, particles and coating condition

Recommended Equipment

Systems to compare

The final specification follows process testing and production analysis.

Process Controls

Control the variables that change the cleaning result

Confirm the part, soil, loading and final handling before fixing equipment settings.

Control 01

Material and geometry

Record surfaces, cavities and features that can trap air or liquid.

Control 02

Soil condition

Test the heaviest representative contamination, not an ideal sample.

Control 03

Basket loading

Keep acoustic access and part spacing consistent with production.

Control 04

Rinse and drying

Match downstream handling to residue and corrosion risks.

System Selection

Match the cleaning route to production flow

Stage count and automation follow the validated process and required output.

Batch

Single-tank route

Compare for focused washing where rinsing and drying are managed separately.

Multi-stage

Wash, rinse and dry

Add controlled stages when carryover and final condition matter.

Automatic

Repeatable transfer

Evaluate automation when output, handling or recipe control requires it.

Acceptance

Define how the cleaned part will be checked

Use the same practical inspection method for trial samples and production parts.

  • Agree the surface or residue limit
  • Check hidden and difficult features
  • Record rinse, drying and handling conditions
  • Compare results before the next operation

Representative Trial

Confirm the process with real parts and loads

Trial evidence should cover normal production and the most difficult expected condition.

  1. DescribePart, material and contamination.
  2. LoadUse realistic spacing and orientation.
  3. TestRecord chemistry, time and temperature.
  4. VerifyInspect with the agreed method.
