The Surface Solution Isolation Source from 4D Technology Corp. is designed for the AccuFiz Fizeau laser interferometers.
The fiber coupled source excludes all but the surface of interest, making it simple to measure flat, transparent optics with physical thickness as thin as 200 μm. In a single setup, both the front and back surfaces of an optic can be measured without repositioning. Transmitted wavefront error, homogeneity and optical thickness can then be obtained from a combination of measurements.
Its compact, lightweight design is extremely rigid for maximum stability in any orientation or environment. Wavelengths from 355 nm through 1.064 μm, apertures from 33 to 800 mm and horizontal and vertical mounting configurations provide the right options for a wide range of applications and budgets.
