Litchfield is the glass and optics plant, with machining, grinding, polishing, coating, assembly, and inspection under one roof. Alexandria is IRD Ceramics, with dedicated hard-material processing and controlled-environment capability.
Both plants use cell-based manufacturing. A cell carries the customer or product line from material through final inspection and shipping, supported by Lean methods, Six Sigma, and metrology. The purpose is straightforward: preserve process knowledge and reduce the variation created by handoffs.
