Here's a shot showing 2 of these lenses being used in a configuration from 2002.
So we now know that at least 2 of these lenses exist and were around as far back as 1996.
The configuration is called the CRL-ASI, here's a description;
As an objective lens, the CRL-ASI has a fish-eye lens with a 6mm focal length and F1.4 made by Nikon Technologies Inc. It is capable of a 180deg all-sky field of view, which enables it to observe a wide area within a radius of several hundreds km range around the observation point. Rays of light pass through the objective lens and then through a collimator lens to become a collimated beam, through an interference filter for spectral separation and is then focused on a CCD device unit. This optic system is based on the all-sky auroral imager developed by the National Institute of Polar Research (NIPR) in 1996 as well as on the airglow-observation-imager developed later at Kyoto University. Interference filters are mounted on the five-channel filter turrets, enabling observation at any of five channel-selected wave-lengths. The telecentric lens has a focus-adjusting mechanism to enable the capture of high-resolution images. The detector unit is a cooled camera with 512 X 512-pixel back illuminated CCD, achieving high-sensitivity and convenient in handling.
