O p t i c s 507 Email: sales@newport.com • Web: newport.com TECHNICAL REFERENCE AND FUNDAMENTAL APPLICATIONS LENS SELECTION GUIDE SPHERICAL LENSES CYLINDRICAL AND SPECIALTY LENSES OPTICS SETS OPTICAL SYSTEMS MIRRORS PRISMS High-Energy Pinhole Apertures • High laser damage threshold • Ultra-thin substrate minimizes laser power loss • Smooth, round apertures • Available mounted or unmounted Our high-energy pinholes are fabricated from ultra-thin molybdenum, a refractory alloy with high heat conductivity and melting point. This material exhibits almost no warping due to localized heating by the laser. A smooth hole with extremely low ellipticity is produced using laser drilling techniques. They are available unmounted or mounted for use with our Model 900 or 910A spatial filters.
