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
