Seismic isolation table, no laser interferometer, FizCam2000
4D Technology Corp. FizCam2000
By eliminating or minimizing the need for a seismic isolation platform and using a short-coherence laser, it is possible to select the measurement surface even with multiple interference surfaces present.
By using a short-coherence laser (with a narrow interference range) and creating a spatial delay in one of the two optical systems divided internally, it is possible to perform interference measurements on any two selected surfaces, even in complex optical systems where multiple surfaces overlap. Unlike methods that create non-measurable areas in reflective systems (such as Hindle mirrors), this transmission-type system allows for the measurement of the entire surface in one go. It is ideal for confirming the final performance of secondary mirrors in telescopes, large stepper lenses, and wavefront-preserving optical systems. Additionally, it has now become possible to measure the behavior of the writing process of HDDs in operation, even in overlapping states, which was previously impossible.

basic information
A Fizeau interferometer capable of simultaneously measuring four phases instantaneously, eliminating the need for and minimizing the vibration isolation table that was essential for measuring large optical systems. It demonstrates excellent resolution with a 1000x1000 pixel camera. With outstanding analysis software, it performs Zernike, Seidel, and Fourier analysis and outputs in 2D/3D images. The data formats from Zygo and Wyko can be repurposed, allowing for the utilization of past data.

Applications/Examples of results
◎ There is a measurement record of the next-generation Hubble Space Telescope (JWST) secondary mirror (convex mirror, 800mm diameter) at NASA. ◎ This device is the only one that can perform "Remote Cavity" measurements, which allows for the free selection of reference surfaces, something that cannot be replicated by other interferometers! ◎ The operational state of the HDD can be measured simultaneously in multiple instances during both stationary and rotating conditions, making it possible to evaluate the writing process.
