Abstract
The techniques of this disclosure relate to determining an optical characteristic of a camera. The device includes a housing that receives a test fixture retaining a camera. The housing includes a first segment and a second segment creating a chamber surrounding the camera. The first segment is attached to the test fixture and defines a first orifice located in a side of the first segment. The first orifice directs a flow of a gas out of the chamber. The second segment defines a second orifice located in a first side of the second segment to direct the flow of the gas into the chamber. An aperture is located in a second side of the second segment and positioned opposite the test fixture to define a field of view that includes a camera target. The aperture receives a lens barrel of the camera and enables the determination of the optical characteristic.
