Six useful questionsDescribe what you need from transparent part inspection before choosing a solution
For in-line inspection of transparent components, share the normal condition, realistic range and difficult cases the finished system must handle.
Question 1Visible Defect or Measurement Definition for Inspection of Transparent Components
Define the visible defect or measurement decision and its acceptable limits. Include scratches, contamination or shape concerns only where they are in scope, and identify the surfaces the optical trial must distinguish.
Question 2Good, Bad and Marginal Sample Range
Supply representative good, bad and marginal transparent parts, including defects at the rejection boundary. Record normal variation and relevant supplier, batch, age, environment or upstream-process differences so the trial reflects the production range.
Question 3Part Presentation and Production Speed
Describe how parts are presented and the normal and credible extremes of production speed. Trial contrast, presentation and timing under realistic line conditions, including the difficult cases the finished system must handle.
Question 4Optics, Lighting and Environmental Conditions
Compare backgrounds, lighting and viewing angles with representative parts in the expected environment. Document which defects and surfaces the setup can distinguish, and the conditions needed to make that visible result repeatable.
Question 5Recipe, Reject and Line-Control Interfaces
Agree operating modes, line handshakes, recipes, reject handling, faults and recovery with the line team. Define the identifiers, results and retention records needed for the agreed inspection checks.
Question 6False-Accept, False-Reject and Challenge Criteria
Agree the false-accept, false-reject and challenge criteria, trial method, repetitions and result record. Include normal, difficult and fault conditions, and define the response when a result falls outside the agreed range.
