Microscope Illuminators

Fiber optic and LED illumination for cleanroom inspection, metrology, and critical manufacturing.

Illumination is the difference between “seeing a defect” and missing it. In cleanroom microscopy, a stable, uniform light source improves contrast, reduces glare, and helps operators identify particles, scratches, residues, and surface defects during inspection. SOSCleanroom offers microscope illuminators engineered for controlled environments—including fiber optic and LED illuminators—to support consistent, high-clarity viewing in semiconductor, aerospace, medical device, pharmaceutical, and laboratory workflows.

Our roots are in optics. SOS began in 1981 as a microscope distributor and evolved alongside the semiconductor industry, which is why we approach illuminators as production-critical equipment—not accessories. Many legacy fiber optic systems rely on tungsten-halogen sources, but global “general lighting” halogen phase-outs and reduced manufacturing have made certain halogen replacements harder to source—so facilities increasingly standardize on reliable illuminators and plan proactively for continuity.
