lensemencement

Lensemencement is a term used in certain discussions of optical design to denote the initial phase of conceiving, modeling, and preparing to manufacture a lense system. The word blends lense and commencement, signaling a deliberate start to the design and validation process rather than the final production. The concept is not widely standardized and appears primarily in design glossaries and speculative discussions about early-stage lens development.

In practice, lensemencement encompasses activities such as defining performance requirements, conducting optical simulations, performing tolerance analysis, and planning the prototyping and metrology strategy. It aims to align engineers, manufacturers, and stakeholders on the intended optical performance and manufacturability before committing to detailed design work. The process typically includes: requirement capture; optical modeling and ray-tracing; tolerance budgeting; mechanical interface and mount design; material selection; risk assessment; and a plan for initial prototypes and verification tests.

Benefits include earlier detection of feasibility issues, clearer expectations for cost and lead times, and a more integrated design-to-manufacturing workflow. Critics note that, because lensemencement is not a standard term, its exact scope can vary between organizations, potentially causing confusion with related concepts such as early-stage optical design, tolerance analysis, or design reviews.
