MES-6001 Radian apparatus
Lens clock measuring instrument is a mechanical dial indicator (also known as a dial gauge) that is used to measure dioptric power of a lens. A lens clock measures the curvature of a surface, but gives the result as an optical power in diopters.
- A black case is included to store and protect gauge.
- Double scale.
- Measures base curve (plus or minus) in a quarter dioptric scale.
- Provides accurate readings.
- Protection cap for tips.
