High-Energy Pinhole Set, Molybdenum, 0.875-20 Thread

0.875-20 Threaded High Energy Molybdenum Pinholes

The 910PH-SET Mounted Pinhole Set includes the following pinhole sizes: 5-, 10-, 15-, 25-, and 50-micron. Each pinhole comes mounted into an 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. The 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 ± 10% toleranced 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.
