NanoSilica Size Standards

Silica is the material of choice for calibrating high-sensitivity inspection systems with intense DUV light sources because they are stable under exposure to DUV radiation. PSL (polystyrene latex) absorbs DUV radiation and volatilizes, so PSL spheres shrink upon inspection.
