I. Cleaning of Sapphire Infrared Windows During the Manufacturing Process:
After coarse polishing: Remove polishing powder, grinding residues, and other stubborn contaminants. VGT ultrasonic technology efficiently cleans sub-surface damage layer attachments.
Pre-coating cleaning: Ensure the substrate is absolutely clean (free of fingerprints, grease, particles). Ultrasonic + chemical cleaning (e.g., IPA + deionized water) is a common industry solution.
Pre-bonding treatment: If the sapphire infrared window needs to be bonded with other optical components. Ultrasonic treatment can enhance surface bonding compatibility.
Frequency selection: VGT ultrasonic manufacturer recommends high frequency (80-120 kHz) combined with low power to reduce potential cavitation impact on the surface.
Cleaning agent compatibility: Avoid acidic/alkaline solutions that may corrode the sapphire infrared window (pH neutral is preferred).
Drying process: Immediately after cleaning, use a dust-free oven or nitrogen drying to prevent water stains. (VGT VGT-1207FT ultrasonic cleaner comes with a drying tank).
II. Technical Parameters, Structural Design, and Core Advantages of VGT VGT-1207FT Ultrasonic Cleaner in Pre-Coating/Pre-Assembly Cleaning of Sapphire Infrared Windows:
1. Technical Parameters:
Parameter Category | Specifications | Significance for Sapphire Infrared Window Cleaning |
Ultrasonic Frequency | Adjustable range 40-120 kHz (default recommendation 80 kHz). | High frequency (≥80 kHz) cavitation is gentler, reducing surface micro-damage. |
Power Density | Adjustable power, maximum power ≤50 W/L (low to medium power mode). | Avoids edge chipping or pre-coating substrate stress changes due to excessive power. |
Tank Capacity | Standard 7-15 L (specific dimensions to be confirmed). | Suitable for continuous cleaning of small to medium batches of sapphire windows (φ20-100 mm). |
Heating Control | Constant temperature range room temperature to 80°C (accuracy ±2°C). | Enhances cleaning agent activity (e.g., IPA + water mixture works better at 40-50°C). |
Filtration System | Built-in 5μm precision filter (optional 1μm or megasonic rinsing module). | Prevents re-deposition of particles like polishing powder, meeting optical surface particle requirements. |
Drying Method | Supports hot air drying/N? blow-off (requires external gas source). | Avoids water stains, meeting pre-coating cleanliness standards (ISO 10110). |
Control System | PLC touchscreen programming, can store 10 process recipes. | Standardizes cleaning processes for different batches of sapphire infrared windows (time/temperature/frequency). |
2. Structural Design:
Tank Material:
Inner tank: 316L stainless steel + Teflon coating (corrosion-resistant, compatible with acetone, ethanol, and other organic solvents).
Outer shell: 316 stainless steel sealed design. Resistant to acid and alkali vapor corrosion.
Ultrasonic Transducer Layout:
Bottom + sidewall multiple transducer arrays ensure sound field uniformity (sound intensity deviation ≤15% in sapphire infrared window placement area).
Cleaning Basket:
Customized PP/PTFE material支架 (avoids metal contact scratching sapphire infrared window edges).
Safety Protection:
Liquid level sensor + overheating protection prevents dry burning or solvent evaporation risks.
3. Core Advantages:
Optical-Grade Cleanliness Assurance:
High-frequency ultrasound + precision filtration achieves ≤0.1μm particle residue.
Supports optional megasonic rinsing (0.8-1MHz), further reducing sub-micron particle adhesion.
Wide Process Compatibility:
Compatible with various optical cleaning agents: IPA, deionized water, semi-aqueous optical cleaning solutions (e.g., ALCONOX).
Suitable for pre-coating/pre-bonding/pre-cementing cleaning.
Automation Integration:
Reserved RS485 communication interface for integration into automated production line control (e.g., robotic loading/unloading).
Low-Damage Design:
In high-frequency mode, cavitation energy focuses on contaminants rather than the substrate, with sapphire infrared window surface roughness change ≤0.5 nm (Sa) (measured data).
