Methods and designs for providing reduced sensitivity to mirror tilt in Fourier transform spectrometers are disclosed. According to an embodiment for two-directional tilt compensation, the FT spectrometer can include a beam splitter positioned to receive an incoming beam from a light source and split the incoming beam into a first sub-beam and a second sub-beam, a comer-cube retroreflector positioned to receive the first sub-beam from the beam splitter, a dual reflective mirror positioned to receive the first sub-beam from the corner-cube retroreflector at one surface and the second sub-beam at the other surface. An optical path delay can be created using a set of mirrors, tilting the beam splitter and/or a glass cube.
