We have developed an objective for ultraviolet imaging and spectroscopy under cryogenic conditions. The objective was made of a single piece of silica with two spherical mirror surfaces. The pair of mirrors works as a reflecting objective for the optical rays that travel inside the silica. The extra refraction at liquid helium–silica interfaces was found to cause practically no chromatic aberration in the wavelength region from 360 to 980 nm. Using the objective with a focal length of 2 mm and a numerical aperture of 0.6, imaging an area of 130 μ m × 130 μ m is possible with almost diffraction-limited quality.

  8. In the measurement of Figs. 3(a) and 3(b) of our previous work in , we erroneously measured the backside of the sample plate. This causes the inconsistency between Figs. 3(a) and 3(b) of and Fig. of this paper. In the blue curve of the shorter wavelength peaks at a positive Δz and the red of the longer wavelength at a negative Δz, but vice versa in this work.
