We report on the fabrication of an all-glass vapor cell with a thickness varying linearly between (exactly) 0 and ~ 1 {\mu}m. The cell is made in Borofloat glass that allows super polish roughness, a full optical bonding assembling and easy filling with alkali vapors. We detail the challenging manufacture steps and present experimental spectra resulting from off-axis fluorescence and transmission spectroscopy of the Cesium D1 line... (read more)
