The A&R DUAL LENSMAPPER is the perfect tool to achieve a very high optical quality control of your free-form lenses:
The DUAL LENSMAPPER combines two optical technologies (Reflection and Transmission) for a fast, accurate and automatic measurement.
Why is the DLM the most accurate mapping instrument on the market?
The DUAL LENSMAPPER is the only mapping instrument that takes into account the effect of the lens position and tilt in the calculation of the theoretical power. This leads to a meaningful error map which is not affected by those parameters.
The measurement principles are simple and mastered leading to an accurate mathematical model for the calculation of the error map.
A single camera is used for every operation ensuring a perfect matching between the reflection and transmission measurements.
