Highlights
- High precision Fizeau workshop interferometer OWI 150 XT invers for testing of spherical and aspherical surfaces.
- High precision kinematics and a working range up to Ø 150 mm make this measuring machine an indispensable tool for the production of high-end optics.
- Optimized for use at the production level
- Measuring stand made of shock-absorbing granite for highest accuracy and rigidity
- Mounted on passive air dampening elements on stable steel base frame
- Radii slide with free from play pre-loaded antifriction bearing, driven by servo motor, variable speed via joystick, travel 1050 mm
- 3-axis table (5-axis table available on option)
- Heidenhain glass scale with 5 μm measuring accuracy for the total travel for absolute measuring precision of radii, scale mounted close to the optical axis (Abbe’s principle)
- Innovative, service friendly mounting of current types of interferometers (MAHR MarOpto FI 1100 Z, Zygo GPI/Verifire 4Inch and 6Inch)
Options:
- Two table version (asphere- and system measuring options)
- Plano measuring by additional tip and tilt table
- Various ring holders
