Paper Abstract

A tilt-tolerant collimating objective lens for dual-band interferometry has been designed. The lens is a 6-inch aperture f/5 all-spherical design, and is parfocal at 0.6328 and 1.061 micron. Optical correction is better than 1/20 wavelength peak-to-valley OPD at each wavelength, over a 0.34-deg (0.178 arcsec) field. Fabrication tolerances for this lens are challenging but realistic.
