    Abstract: The invention provides a polishing pad suitable for polishing integrated circuit wafers. It includes an upper polishing layer that having a polishing surface and at least one groove in the upper polishing layer. At least one transparent window is located within the upper layer. The at least one transparent window has a thickness greater than a desired wear depth of the at least one groove. The at least one transparent window includes a non-fluorescent transparent polymer; and a fluorescent transparent polymer. The transparent window allows measuring groove depth by activating the fluorescent transparent polymer with an activation source at a wavelength sufficient to excite the fluorescent transparent polymer and allow endpoint detection by sending light through the fluorescent transparent polymer and the non-fluorescent transparent polymer.
