High laser damage threshold
Ultra-thin substrate minimizes laser power loss
Smooth, round apertures
Available mounted or unmounted
Our 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.
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.
900PH Series pinholes are designed to work with our 900 Series three-axis spatial filters. 910PH Series pinholes are designed to work with our 910 Series five-axis spatial filters.
