Mahr Metrology MarForm MFU 200 Aspheric 3D

The MarForm MFU 200 Aspheric 3D is a high-precision 2D/3D measuring system for optical components, enabling fast, accurate inspection close to production.

  • High-precision axes: Z-axis 200 mm, flexible X-axis for accurate form, position, and axial runout measurement.
  • Fully automated operation: Minimal operator intervention with automatic centering and tilting table.
  • Versatile sensor positioning: Optical and tactile sensors can rotate 0°–360° via motorized swivel joint.
  • Applications: Optical free forms, off-axis aspheres, toroids, radius of curvature, conical constant, and aspheric coefficients measurement.

Description

The MarForm MFU 200 Aspheric 3D is designed for fast and accurate inspection of optical components in both 2D and 3D. With decades of proven stability and precision, this high-precision measuring instrument supports process optimization with very low measurement uncertainty. The vibration-damped cabin prevents interference from vibrations and dust, ensuring reliable results even in near-production environments.

The system features motorized swivel joints, allowing optical and tactile sensors to be positioned in any angle from 0° to 360°, giving maximum flexibility for complex optical geometries. Measurement parameters such as RMS value, PV value, gradient error, and asphere coefficients (R0, k, Ai) can be adjusted to match target specifications. Practical applications include measuring shape deviation of optics, circumferential cylinder dimensions, optical axis offset, tilting on lens undersides, and more. The MFU 200 Aspheric 3D also enables the measurement of optical free forms, off-axis aspheres, and toroids, making it an indispensable tool for optical component quality assurance.
