Far ultraviolet absorption spectra ofporcine and human comeas

We have measured the absorption spectra ofporcine and human comeas in the far ultraviolet region from 350 nm to 190 nm. The samples were sectioned from frozen comeas into thin slices of 15 tm to 40.tm in thickness. The absorption spectra shows three distinct regions from 260 nm to 190 nm: a relatively weak absorption regio
