The 910PH-75 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 75 ± 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.

910PH-75高能针孔孔径由超薄钼制成，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75±5μm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。每个针孔都安装在一个黑色的阳极化铝阀体上，该铝阀体螺纹(0.875-20)与910五轴空间滤波器或LP-05A多轴透镜支架之一一起使用。
