Mapper
Rotlex Mapper is a high-resolution lens inspection system for spectacle lenses.
Within 3 seconds, the Mapper provides high resolution power and cylinder maps, of all types of lenses: Spheric, aspheric, toric, atoric, front, back and double progressive, bifocal, trifocal, polarized, unpolished, and more.
Other than the prescription values (Sph, Cyl, Ax, Add), the maps provide a huge wealth of information:
Lens design issues:
- Corridor width
- Corridor length
- Symmetry
- Size of far vision zone
- Size of near vision zone
- Amount of distortions
- Soft/Hard power progression curve
- Other power distribution issues
Lens manufacturing issues:
- Blocked corridor
- Power or cylinder “Islands”
- Lateral shift in marking
- Left/Right printing errors
- General distortion
All these enable the following applications:
- Verification of the prescription
- Measuring unmarked lenses and finding the vision circles (can be done automatically)
- QA – finding bad lenses with all types of defects
- Detecting printing errors
- Checking whether lens and frame match (by overlaying frame contour on the map)
- A powerful tool for lens development as well as process optimization
- Comparing competitors lenses to yours
- Periodic testing for mold quality degradation
- Marketing – Demonstrate the quality of your lenses
