Abstract
We report on the design and testing of a multiwavelength interferometry system for the Orion laser facility based
upon the use of self-path matching Wollaston prisms. The use of UV corrected achromatic optics allows for both
easy alignment with an eye-safe light source and small (∼ millimeter) offsets to the focal lengths between different
operational wavelengths. Interferograms are demonstrated at wavelengths corresponding to first, second, and
fourth harmonics of a 1054 nm Nd:glass probe beam. Example data confirms the broadband achromatic capability
of the imaging system with operation from the UV (263 nm) to visible (527 nm) and demonstrates that features
as small as 5 μm can be resolved for object sizes of 15 by 10 mm. Results are also shown for an off-harmonic
wavelength that will underpin a future capability. The primary optics package is accommodated inside the footprint
of a ten-inch manipulator to allow the system to be deployed from a multitude of viewing angles inside the
4 m diameter Orion target chamber
