TITLE(s): OPTICAL-ELEMENT COATER (optical goods)

Controls vacuum coating equipment to coat optical elements with chemical or metal film to alter reflective properties of elements: Reads work order to ascertain thickness of optical element and type coating material specified. Installs heating filament in coating machine according to type coating applied, using screwdriver. Fills crucible with coating material and positions crucible under heating filament. Secures optical element in jig and centers jig in vacuum chamber of machine to ensure uniform coating of optical surface. Places dome-shaped lid (vacuum bell) over jig or lowers lid equipped with window depending upon machine used. Starts machine that creates vacuum and releases chemicals or metal to form coating on optical element by process of sublimation or atomization. Observes changing colors of element through vacuum bell or through window in lid to determine when element is coated to specifications, or reads exposure meter to determine coating thickness. Applies and removes strip of cellophane to test adherence of coating to optical element. May immerse elements in chemical solution to clean elements. May operate ultrasonic vibrator to clean element. May inspect optical elements prior to coating to detect defects, such as blemishes, abrasions, and rough edges, using microscope. May cement optical elements together to form multiple laminated elements [CEMENTER (optical goods)]. May spray emulsion on lens preparatory to coating.
