     The production of optical and UV Cherenkov and transition radiation (TR) photons in stacks of identical and different transparent plates by high energy particles and heavy ions is considered. With the decrease of the thickness of the plates the Cherenkov radiation losses its threshold behavior, and the angular distribution of the produced Cherenkov-transition radiation becomes much wider. Possible construction and use of RICH like detectors with such radiators are discussed.
