Workshop Topics
Join 4D Technology in Colorado to learn about Dynamic Interferometry and experience the latest in optical metrology. This workshop will occur on August 20 and cover topics such as:
Theory and Practical Aspects of Dynamic Interferometry
for 3D Shape, Transmitted Wavefront Measurements, and Optical System Alignment
- What it is, how it works
- Unique capabilities using dynamic interferometry
- When to use a Fizeau versus Twyman-Green interferometer
- What is ITF and why does it matter in detecting mid-spatial frequencies and other manufacturing artifacts
Applications of Dynamic Interferometry
- Ground and space-based telescopes
- Optics shop measurements
- Improved interferometric configurations for superior testing of IR components and systems
- Short-coherence dynamic interferometry to enable measurement of thin and plane-parallel optics
- Supersmooth measurements
- Radius of curvature measurements
- Portable surface roughness measurements
- 3D optical inspection system for defect, chamfer and edge break analysis
Hands-On Experience with Dynamic Interferometers
- PhaseCam: Our highest performance Twyman-green interferometer, with patented, vibration-insensitive measurement capability for concave and long cavity measurements.
- AccuFiz Duo: New! Two laser sources which enables both short coherence on axis dynamic and long coherence phase shifting interferometry for measuring thin, transparent optics or digital hologram measurements all in one system.
- NanoCam: A small, non-contact optical profiler for vibration-immune roughness measurement that can be handheld or mounted on a robot.
- InSpec: A handheld, precision instrument for non-contact surface feature and defect measurement with um-level resolution.
- InSpec SR: A handheld 3D surface roughness system with nm-level resolution.
Plus, we’ll be demonstrating the latest functionality of 4Sight Focus, including real-time Zernike alignment, advanced island leveling of mirrors and telescope optics, and geometric transforms; and previewing our next release with new fiducial capabilities, aspheric Zernike functionality and more.
