Abstract
A protective nozzle for protecting a frontal optical portion of a laser camera has a body attachable to the laser camera, apertures extending through the body, a transparent plate extending crosswise to and blocking each aperture on a back side of the body, contouring air pockets recessed in the back side of the body, under the transparent plate and extending around the apertures with lips projecting around the apertures to define air gaps for escape of pressurized air from the contouring air pockets toward the apertures in a form of centripetal air jets along the transparent plate, and an air passage arrangement extending in the body from an air inlet located on a side of the body for receiving pressurized air to the contouring air pockets.
