Newport MKS High-Energy Pinhole, Molybdenum, 40 µm, 900 Series 900PH-40

The 900PH-40 High Energy Pinhole Aperture is 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 40 ± 4 μm diameter hole with extremely low ellipticity is produced using laser drilling techniques. These pinholes have a laser damage threshold of 75 MW/cm2 CW and are suitable for pulsed laser use up to 700 mJ/cm2. This version is mounted for use with our Model 900 spatial filter.
