OptiSurf® LTM - Non-contact and Precise Lens Thickness Measurement
In optics production, precise optical systems require high quality in single lenses. With the OptiSurf® LTM, TRIOPTICS has developed a non-contact center thickness measurement system for single lenses which integrates outstandingly into every production.
Center thickness measurement using low-coherence interferometry:
The self-centering clamping chuck is easily adapted to different diameters:
For measurement of small samples a second self-centering clamping chuck is optionally available:
- Standard clamping chuck for lens diameters of 8 mm to 200 mm
- Micro clamping chuck for lens diameters of 1 mm to 30mm
Key Features:
- Optimized for center thickness measurement of single lenses in production
- Integrated touch screen for easy operation
- USB interfaces for bar code scanners and other auxiliaries
- Self-centering, mechanical clamping chuck
- Vibration damping
Applications:
- Non-contact center thickness measurement of single lenses and doublets
- Thickness measurement of optical elements
- Measurement of sag value
