Spindler & Hoyer NL Optical Mirror Fixture Clamp Laser Alignment Precision Lab

Spindler & Hoyer NL Optical Mirror Fixture Clamp Laser Alignment Precision Lab

The Spindler & Hoyer NL is a precision optical mirror fixture designed for exact alignment and centering tasks on lab benches and optical setups. The clamp-style base features a matte black platform with a U-shaped cradle that holds a circular mirror disk flush in a centered cutout, providing a stable, repeatable reference surface for optical axis alignment work. A small access hole is present on the inner wall of the cradle. Spindler & Hoyer (now part of Qioptiq / LINOS) is a long-established German manufacturer known for precision optical and opto-mechanical components used in research, metrology, and laser systems.

Applications

Optical mirror fixtures of this type are used in laser beam alignment, optical axis centering, and interferometry setups where a mirror must be positioned and held at a precise, repeatable location. The U-cradle design allows a circular mirror disk to sit flush and centered, making it straightforward to establish a reference plane on an optical breadboard or lab bench. Spindler & Hoyer manufactured a range of opto-mechanical mounting hardware of this kind for use in university research labs, metrology benches, and industrial laser systems — applications where positional repeatability matters and the fixture must be stable under continuous use. This type of component is still in active use in optics labs and photonics research environments that work with beam steering, wavefront testing, or laser cavity alignment.
