technology has been licensed to a large company for human translational commercialization I'll skip some of the details on the engineering side and this is by the way this is the first photo Costa endoscope we can also implement a photo acoustic microscopy at even finer resolution so if we sacrifice the penetration now we're back within one millimeter penetration these we do want to cover the very top layer of the of the thickness so you can focus light more tightly that allows you to get finer resolution and you do have to
