Please use this form to tell us about the precision optical components, coatings, or assemblies that you need.
Precision Optical utilizes a variety of interferometers and interferometric techniques in order to meet the demands of the optics industry. From static fringe analysis on the shop floor, to ultra-precision measurements using both dynamic and temporal phase-shifting interferometers, Precision Optical relies on its interferometry to measure various optical specifications. Surface figure, irregularity, radii, transmitted wavefront error, aberrations, 90 Deg angles, beam deviation (transmitted and reflected), wedge magnitude/parallelism, slope magnitude, and homogeneity testing are just some of the analysis that Precision Optical can perform. We can import/export the following dataset formats: 4D (.h5), Wyko/Veeco (.opd), Opticode (.map), MetroPro (.dat), CODE V (.int) or ESD, HDF4 (.HDF).
Precision Optical manufactures the majority of its own transmission and reference flats to better than lambda/40. With our Zygo 450mm reference flat we have the capability of measuring transmitted wavefront and performing homogeneity testing over large apertures. We also have an AOS custom electronic tip/tilt mount capable of holding up to 520mm diameter optics (larger optics capable upon request). We manufacture our own tip/tilt plates and tooling for custom applications. We are very familiar with setups including: single-pass and double-pass prism testing, 90 Deg internal and external measurements, parallelism, beam deviation, multiple-region analysis and homogeneity testing. RMS simple repeatability typically is on the order of lambda/10,000 and angular accuracy is ± 0.1 arc seconds.
