Description
Product Introduction
The Komatsu AIH-123QS-PP-UC is a specialized, precision-engineered UV lamp housing and light source module manufactured by Komatsu. Designed primarily for high-precision semiconductor fabrication equipment, photolithography exposure tools, and industrial UV surface modification systems, this unit provides a highly stable, thermally managed enclosure for ultra-high-pressure mercury or excimer UV lamps.
Engineered to operate in demanding manufacturing cleanrooms, the AIH-123QS-PP-UC ensures maximum optical transmission while isolating high-voltage discharge connections. Its integrated cooling channels prevent thermal deformation of optical components, and its precision-machined housing ensures precise beam alignment with downstream illumination optics.

Application Scenarios & The “Trench” Experience
In semiconductor wafer fab lines or precision LCD/OLED panel manufacturing, optical alignment and constant UV intensity are critical to sub-micron patterning. If a lamp housing suffers thermal expansion due to clogged cooling lines or degraded quartz windows, the beam drift can cause uneven exposure, ruining entire production batches.
Swapping in a certified Komatsu AIH-123QS-PP-UC module restores precise optical alignment and thermal equilibrium. The drop-in module architecture allows field service engineers to execute rapid lamp replacements during scheduled maintenance windows without re-engineering the primary optical path.
- Semiconductor Wafer Photolithography – Housing primary UV light sources for stepper and scanner exposure tools.
- Flat Panel Display (FPD) Manufacturing – UV curing and substrate alignment exposure in cleanroom production tools.
- Surface Cleaning & Modification – High-intensity UV/Ozone surface treatment systems for silicon wafers and optical glass.

Transparency SOP: Quality Assurance & Testing
We don’t just ship hardware; we thoroughly inspect and bench-test specialized semiconductor components. Every surplus or refurbished Komatsu AIH-123QS-PP-UC module undergoes a strict 5-stage verification process prior to dispatch:
- Inbound Physical & Optical Inspection: Visual check of the anodized chassis, mounting rails, quartz window clarity, and internal reflective coatings for scratches or deposition buildup.
- High-Voltage Isolation Audit: Insulation resistance testing across internal high-voltage lamp feedthroughs to verify zero arc-over risk.
- Cooling Loop Hydrostatic Test: Internal cooling channels pressure-tested to confirm leak-free operation under nominal coolant flow rates.
- Mechanical Alignment Check: Verification of internal lamp adjustment mechanisms and precision positioning screws to guarantee smooth mechanical movement.
- Cleanroom Decontamination & ESD Shielding: Cleaned according to semiconductor handling standards and vacuum-sealed in ESD and moisture-barrier protective packaging.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Handle Optical Windows with Extreme Care: Never touch the quartz output window or internal reflectors with bare hands. Skin oils will burn into the quartz glass under intense UV radiation, creating permanent thermal hot spots that degrade optical throughput and shatter the window. Always wear lint-free cleanroom gloves and use optical wipes with pure isopropyl alcohol.
❗ Verify Coolant Line Flow Before Power-Up: Ensure the coolant supply lines (Deionized Water or Glycol loop) are fully purged of air bubbles before energizing the lamp. Running high-wattage UV lamps inside the AIH-123QS-PP-UC without active coolant flow will instantly overheat internal seals and destroy the housing.
⚠️ Check High-Voltage Feedthrough Connections: Industrial UV lamps require high-voltage ignition pulses to strike the arc. Verify that the high-voltage electrical leads inside the housing are fully insulated and free from oxidation or dust accumulation to prevent arcing to the chassis.
❗ Observe OEM Part Number Suffixes: Suffixes like -PP-UC denote specific internal reflector coatings, cooling fitting types, and window specifications. Always cross-reference your tool’s manual to ensure the -PP-UC revision matches your machine’s exact optical requirement.
Frequently Asked Questions (FAQ for Conversion)
Q: Does the AIH-123QS-PP-UC come pre-installed with a UV lamp?
A: Typically, lamp housing assemblies are supplied without the consumable UV lamp bulb unless explicitly requested. This ensures you can install a brand-new OEM lamp specified for your exact exposure recipe.
Q: Is the optical output window replaceable on this housing?
A: Yes. The synthetic quartz output window is a serviceable component designed to be replaced if solarization or surface contamination occurs after extended UV exposure hours.
Q: What equipment manufacturers use this Komatsu light source assembly?
A: Komatsu light source and thermal control modules are commonly integrated into specialized Japanese and global semiconductor manufacturing tools, photolithography exposure systems, and industrial UV processing equipment.
Q: What warranty is provided with this unit?
A: All our new surplus and bench-inspected refurbished Komatsu modules come backed by a full 12-month replacement warranty.
