The CFAT5 is designed for use in vertical, laminar air flow cleanrooms.The narrow, airfoil design minimizes turbulence in clean-rooms thatrequire a uni-directional air flow. The corrosion resistant extrudedaluminum housing measures 1-1/2 in width to allow mounting to amatching 1.5 T-bar. The lens utilizes internal prisms providing opticalcontrol while providing a smooth environmental side.
