An apparatus for testing optical filters comprises a gantry system supported on a base or floor, including structure translatable in the X and Y directions relative to the base. The apparatus further includes a support mounted on the structure and a translatable platform disposed adjacent the structure. The support is translatable in the Z direction relative to the base. The apparatus further includes a flexure mounted on the platform, a probe assembly mounted on the support, and a light-directing element. The flexure is adapted to retain one of the optical filters. Translation of the platform causes the platform-mounted flexure to be translated from a first X, Y and Z position relative to the base to a second X, Y and Z position relative to the base. The probe assembly is adapted to pick up one of the optical filters from a third X, Y and Z position relative to the base and translate the picked-up optical filter to the first position for retention of the picked-up filter by the flexure. The light-directing element is disposed adjacent the second position, is optically connected to a coherent light source, and is adapted to direct coherent light at an angle that is normal to the flexure-retained optical filter translated by the platform to the second position for testing the optical filter.
