“…Fabricating such long, narrow, and smooth channels has proven problematic. Lens prototypes have been created using microchannel plate technology (MCP) [8,9,11,12] and etched silicon [13]. However, these lenses are extremely limited in their spectral range because of material [11,13].…”

The lobster-eye telescope with square cross-section channels has been suggested as a possible candidate for a wide-field-of-view x-ray all-sky monitor. However, due to the difficult construction, especially with metals, variations of lobster-eye lenses have been proposed as possible alternatives. This work is a computational comparison of the focal properties of one variant, the meridional lens, with the square-channel lens. For both types of lens, the efficiency of focusing for imaged photons as well as the point-spread function in one dimension is studied for collimated sources.

“…If the number of reflections in the X-direction is odd but that in the Y-direction is even (or vice versa), the ray will be focused only in one dimension. Such rays will create a cross-shaped pattern around the focus [4] . Finally, if the number of reflections in both X-and Y-directions is zero, the ray will propagate through the lens undeflected and will contribute to practically uniform background exposure of the image surface (in practice, this background pattern is separated into rectangular sections by the shadows of the lens mirrors).…”

We propose a new imaging device for the long infrared spectral range, inspired by the natural eye of a lobster. Such a lobster-eye lens is composed of reflecting channels with a square cross section capable of wide angle of view and practically omni-directional imaging. As in large-aperture lenses, aberrations can significantly degrade the image.We show two methods of reducing aberrations: by selecting proper material for the mirrors and by making channels with absorbing sections.
