General Comments on Manufacturing Limits

This represents a general list of soft limits and is intended for reference only.

As requirements move closer to a min or max is shown, the more challenging the part will be.

During manufacturing, the lens is oversized in diameter.

Based on Form Error Tolerance

1Diameter (mm)3400
2Radius (mm)±1∞²
3Aspect Ratio (Diameter/Center Thickness)<1:130:1
4Included Angle (°)0210³
  1. Limited by machine envelope
  2. Metrology dependent. Avoid 3-10 meter radii when possible, choosing to stay plano instead. It will be less expensive too.
  3. This represents the highest values possible. Actual value possible depends on finished and metrology options available plus tolerance range available for a given part.
