Our unmounted high-energy pinholes are 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 hole with extremely low ellipticity is produced using laser drilling techniques.

Features
High Damage Threshold
Molybdenum is a refractory alloy with high heat conductivity and high melting point that exhibits almost no warping due to localized heating by the laser. These ultra-thin molybdenum pinholes have a laser damage threshold of 75 MW/cm2 CW and are suitable for pulsed laser use up to 700 mJ/cm2.
Compatible With 910 Series Pinhole Mount
These high energy unmounted Molybdenum pinholes are compatible with our 910P-MNT pinhole mount. The 910P-MNT pinhole mount features 0.875-20 thread for use with 910A five-axis spatial filter or LP-05A positioners which have the same thread type.
Compatible With 900 Series Pinhole Mount
These high energy unmounted Molybdenum pinholes are compatible with our 900P-MNT pinhole mount. The 900P-MNT pinhole mount features a mounting rod for use with 900 Series three-axis spatial filters.
