Pinhole mirrors in a solid aluminum substrate offer unique light-handling characteristics. With a flatness of 1-2 waves, these mirrors are ideal for lasers, interferometry, high-power telescopes, imaging, and other applications where a through-hole may be useful or required for selective light transmission and reflection.
These mirrors may be used in high power applications where thin-coated glass substrates may normally deteriorate.
Other applications include signal processing, distance measurement, laser filtering, astronomy and more.
Pinhole Mirrors come standard with 3 2-56-TPI tapped holes on the reverse (non-polished) side at 120° bolt circle. Your pinhole mirror will come standard with 3 4/40 screws installed to aid in handling / mounting of the component.
