Measuring in Hostile environments with Dynamic interferometry
Webcast on Dynamic Interferometry
This month, co-founder of 4D Technology, Neal Brock, gave a webcast on Dynamic Inteferometry. In it he explains:
- How it works
- How dynamic interferometry is different from other interferometry
- Things that it has been used for
It’s an eye-opening presentation. Laser Focus World has the broadcast in full, recorded at the link below (requires registration). Watch it now.
Products for Aspheric Optics
AccuFiz 6 MPx
The high resolution 6 megapixel AccuFiz Fizeau interferometer can measure steeper slopes, making it your best suited option for working with aspheres.
4D PhaseCam Twyman-Green interferometers are the industry choice for measuring concave spherical optics, from several millimeters to tens of meters in diameter.
