mirror mount

A mirror mount is a mechanical device used to secure and precisely position mirrors in optical systems. Mirrors are essential components in optical setups for reflecting light or redirecting laser beams. The mirror mount allows for accurate alignment and adjustment of the mirror's orientation to achieve the desired optical performance.

Key features and components of a typical mirror mount include:

Base: The base is the foundation of the mirror mount, providing stability and support for the entire assembly. It is often designed to be securely attached to an optical table or other mounting surfaces.

Adjustment screws: Mirror mounts typically have screws or adjustments that allow users to tilt, pitch, and yaw the mirror. These screws provide fine control over the orientation of the mirror, enabling precise alignment with the optical axis.

Mounting plate: The mirror is usually attached to a mounting plate, which is then connected to the adjustment screws. The mounting plate may have threaded holes or other mechanisms for secure mirror attachment.

Locking mechanism: Once the mirror is properly aligned, a locking mechanism (such as set screws) is used to fix the mirror's position, preventing unintended movement or misalignment.

Angular scales: Some mirror mounts come with angular scales or indicators that provide a numerical reference for the mirror's orientation. This can be helpful for repeatable and accurate positioning.

Mirror mounts are crucial in applications where precise optical alignment is necessary, such as in laser systems, interferometers, telescopes, and other optical experiments. They allow users to make fine adjustments to optimize the performance of the optical setup by controlling the direction of reflected light.
