These high-power precision pinholes are designed to withstand high power densities, up to 10 W/mm2 (10 W/cm2) for CW lasers. These are designed to be used with the beam incident on the gold-plated side. We recommend aligning the pinhole at low power, increasing the laser to full power after ensuring good throughput.

• Precision Copper Pinholes, Gold-Plated One Side, Flat Poly Black
• 25 µm Thickness at Aperture
• Aluminum Housing with 1" Outer Diameter.
