Spheres (Spherical Optics)

4D's dynamic laser interferometers measure the surface shape of spherical optics from several millimeters to tens of meters in diameter. Because 4D systems can measure despite air flow and vibration they can accommodate long stand-off distances, complex test setups and difficult environments without the need for expensive isolation systems.

4D systems measure coated and uncoated spheres, in wavelengths from deep UV through IR and diameters. Optional accessories and diverging optics simplify measurement setup for accurate measurement of focal optics and opto-electronic systems.

4D laser interferometers feature 4Sight software for comprehensive analysis of spheres, including Zernike and Seidel analysis, slope analysis, and much more.
