High-Energy Pinhole, Molybdenum, 25 µm, 0.875-20 Thread

The 910PH-25 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 25 ± 2.5 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. Each pinhole comes mounted into a black anodized aluminum body which is threaded (0.875-20) to be used with either the 910 Five-axis Spatial Filter or one of the LP-05A Multi-axis Lens Mounts.
