The PH-10 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 ± 1 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 unmounted.

PH-10高能针孔孔径是由超薄钼制成的，钼是一种高导热性、高熔点的难熔合金。由于激光局部加热，这种材料几乎不会翘曲。顺利10±1µm直径孔与使用激光钻井技术产生椭圆率极低。这些针孔的激光损伤阈值为75 MW/cm2连续波，适用于高达700 mJ/cm2的脉冲激光。此版本已卸载。
