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.
Claims19
A protective nozzle for protecting a frontal optical portion of a laser camera, the protective nozzle comprising:
- a body attachable to the laser camera, the body having opposite front and back sides and being sized and shaped to cover the frontal optical portion of the laser camera when attached thereto with the back side of the body in direction of the laser camera;
- at least one aperture extending through the body between the front and back sides;
- a transparent plate extending crosswise to and blocking each aperture on the back side of the body;
- an air inlet located on a side of the body for receiving pressurized air;
- for each aperture, a contouring air pocket recessed in the back side of the body under the transparent plate and extending around and spaced from the aperture to form a lip projecting around the aperture toward the transparent plate, the lip having a distal surface spaced from the transparent plate to define an air gap for escape of pressurized air from the contouring air pocket toward the aperture in a form of a centripetal air jet along the transparent plate;
- and
- an air passage arrangement extending in the body from the air inlet to each contouring air pocket.
