Abstract: A filter assembly is configured to optically couple a camera head to an endoscope. The filter assembly includes a first end adapted to be removably coupled to the camera head and a second end opposite and spaced apart from the first end, the second end adapted to be removably coupled to the endoscope. The filter assembly includes an optic housing disposed between the first end and the second end, the optic housing includes an optical path length maximizer and a first window. The first window has a first surface that is angled with respect to a plane that is perpendicular to a longitudinal axis of the optic housing so as to minimize a narcissus reflection within the optic housing and an optical filter to reject laser irradiation.

Abstract: An enhanced fluorescence imaging system includes a light source for emitting non-visible and visible light and a visible light image sensor and a non-visible light image sensor. Each pixel of the visible light image sensor corresponds to a pixel of the non-visible light image sensor. Data processing hardware performs operations that include, for each pixel in the visible light image sensor, determining an intensity of visible light received by the pixel. The operations also include determining, based on the intensity, an amount of unwanted non-visible light captured by the corresponding pixel of the non-visible light image sensor. The unwanted non-visible light originates from sources other than the non-visible light source. The operations also include reducing an intensity of non-visible light in non-visible image data captured by the corresponding pixel based on the determined amount of unwanted non-visible light.

Abstract: A coated substrate and a process for forming the coated substrate, including a first lubricious coating layer overlying the substrate, the first lubricious coating layer including a first lubricant providing to the first lubricious coating layer a first coefficient of friction; and a second lubricious coating layer overlying the first lubricious coating layer, the second lubricious coating layer including a second lubricant providing to the second lubricious coating layer a second coefficient of friction, in which the second coefficient of friction is greater than the first coefficient of friction.
