Ecoclean's High-Performance Cleaning Solutions for Critical Optical Components
In the world of precision optics, cleanliness is not a recommendation—it is a requirement. Optical components such as lenses, mirrors, filters, and prisms are used in sensitive applications across industries like aerospace, laser systems, micro-electronics, semiconductors, and metrology. Even the smallest residue can compromise optical clarity, system performance, and long-term reliability.
Achieving the required Cleanliness Standardsis not a single-step task. It is a stage-wise cleaning process, where each stage is designed to target specific types of contamination and to prepare the component for its next phase-be it inspection, coating, assembly, or packaging.
Stage 1: Intermediate Cleaning – Removal of Manufacturing Residues
This initial cleaning stage is performed immediately after key processes such as grinding, lapping, or polishing. Components at this point are typically coated with coarse contaminants like:
- Abrasive particles
- Polishing pastes
- Cooling lubricants and residues
Cleaning Objective:
To eliminate gross contaminants and prevent their transfer into sensitive downstream cleaning or coating processes.
Ecoclean's Solution:
Multi-stage immersion-type ultrasonic cleaning systems:
- UCMCombiLine:
UCMCombiLine – Ecoclean India
The UCMCombiLineis a modular system consisting of self-sufficient individual stations for the ultrasonic cleaning of components with high cleanliness requirements. The system is available in 5 sizes from 50 to 220 litres. It has dual frequency and can be switched easily as needed.
The system uses ultrasonic cleaning technology, which uses high-frequency cavitation to dislodge and remove contaminants even from complex surfaces.
- UCMBaseLine:
UCMBaseLine – Ecoclean India
The UCMBaseLineis a modularly designed ultrasonic in-line immersion system. It's flexible and well-thought-out system concept offers numerous possibilities for solving individual cleaning tasks with the highest demands on component quality.
- Solvent-Based Machines:
In some cases, solvent-based cleaning machineslike the Minio 85C, Minio 75P, and Universal 81C are especially effective for removing non-polar contaminants such as oils and greases.
This stage plays a foundational role in protecting delicate surfaces from scratches, film formation, or cross-contamination in subsequent cleaning or coating stages.
Stage 2: Final Cleaning – Attaining Optical-Grade Purity
Once coarse residues are removed, components undergo final cleaning to eliminate finer or chemically active contaminants.
This stage typically occurs:
- Before coating or bonding
- Before critical assembly
- Prior to packaging for storage or shipment
- After intermediate inspection
Contaminants Addressed:
- Trace polishing compounds
- Lacquer or ink markings
- Environmental dust
- Fingerprints or glove imprints
- Residues from temporary protection layers
Ecoclean's Solution:
UCMSmartLine:
UCMSmartLine – Ecoclean India
The UCMSmartLineis a modular, immersion-type ultrasonic system with up to nine wash and rinse stages. The versatile system concept offers:
- Parts are agitated in wash and rinse modules, with optional rotary and spinning movements
- Variable ultrasonic frequency operation from 25 to 120 kHz
- Integrated rinsing and multi-stage drying (hot air, infrared, and vacuum)
- Cleanroom compatibility with HEPA filtration
UCMPerformanceLine: Designed for the highest purity requirements.
Features include:
- Pulse Pressure Cleaning (PPC) to dislodge stubborn residues
- Optional passivation and neutralisation stages
- Vacuum-hot-air drying for water-spot-free surfaces
- Fully configurable up to 8 tanks for complex, multi-stage processes
Why Final Cleaning Is Critical:
A spotless surface is essential to:
- Ensure proper light transmission and reflection
- Avoid coating failures or optical distortion
- Extend component life in demanding environments
- Prevent rework or yield loss in precision manufacturing
Understanding the Role of Each Cleaning Stage
Each stage of optics cleaning serves a distinct purpose, and its role is defined by the required cleanliness level for a particular process step—whether it's a pre-coating clean, a post-lapping rinse, or a final cleaning before packaging.
An inadequate intermediate cleaning can overload the final cleaning stage, increasing the risk of contamination or performance issues. Similarly, a clean component can be compromised by improper handling if a cleaning stage before final inspection or packaging is skipped.
