OLYMPUS OLS-ILW DV525301 AQ8967 / DV525402 AQ8970 White LED Illumination Unit – OLS-ILW Series
When the white LED illumination unit in an OLYMPUS OLS-ILW laser scanning confocal microscope fails, the entire inspection line comes to a halt. Surface defect analysis, 3D measurement, and precision optical metrology become impossible — costing manufacturers hours of downtime, missed SLA targets, and potential quality escapes on critical production batches. The OLYMPUS OLS-ILW White LED Unit (DV525301 / AQ8967 and DV525402 / AQ8970) is the OEM-specified illumination component that restores full system functionality with zero compromise on optical performance.
Within the OLS-ILW series, this dual-part LED assembly occupies a critical position: it provides the broadband white-light channel used for simultaneous confocal and color imaging, complementing the laser scanning path. Globally, the OLS-ILW platform is deployed across semiconductor fabs, precision machining QC lines, and advanced materials research labs — making reliable access to genuine replacement parts a strategic supply-chain priority for maintenance engineers and procurement teams worldwide.
