Abstract
The present invention provides for significantly improved ultraviolet optical filters. This new class of optical filters benefits from improved optical performance, extended physical longevity, high imaging quality of transmitted radiation, transmitted wavelength stability, and minimal autofluorescence. Preferred filters of the invention do not require any sealing from the ambient, are stable, and do not degrade over time and exposure to UV irradiation, and offer superior transmittance for use as bandpass filters.
