A new method on the coating layer uniformity was investigated. A method to characterize coating uniformity using a staining technique and a confocal laser scanning microscope (CLSM) was proposed. Burn out tests are compared to the CLSM technique in terms of coating layer evenness. The coating mass distribution was calculated using image analysis software from both methods. A reasonable correlation was found between the burn out test and CLSM observation when the fluorescent dye was not rinsed
