Mechanical Lens Clock, ±20 Dioptres

Measure compatible lens-surface curvature with a mechanical lens clock and analogue scale.

Check lens curvature with a direct reading

• ✅ A mechanical dial provides a visible reference during measurement.
• ✅ A compact body is convenient to keep with optical tools.
• ✅ The ±20-dioptre scale provides a common reference when comparing compatible lens surfaces.

Lens-clock reference: n1.53. Measurement scope: ±20 dioptres. Reading interval: 0.25. Approximate size: 70 × 107 × 22 mm. Weight: 81.5 g.
