We have designed the optics for observing diffusive emission sources by employing an off-axis parabolic mirror in front of a slit which guides lights to a diffraction grating. The reflective diffraction grating is an rotatable ellipse providing angular resolution. We describe our plan to measure the off-axis parabolic mirror and our initial experiments to establish the measurement technique. To assist manufacture of the off-axis parabolic cylinder, a cylindrical wavefront generated by using computer generated hologram(CGH) are used during the polishing process to check errors in surface profile using the Fizeau interferometer.
