Multi-axis lens holders are a convenient way to align a lens to the optical axis. These plate-type holders mount securely and provide a stable low optical axis.

◦Five-axis adjustment type (ALHN-5) allows lens tilt adjustment for applications where achieving the best possible focusing is required.
◦Lens focus adjustment is done by rotating the lens tube with the lever, moving the position of the lens forward or backward.
◦The XY centering adjustments include locking nuts and the focus adjustment includes a locking screw.
◦In addition to single lenses, thick lenses or combined lens tubes up to thickness 28mm can be mounted directly in the holder.

▶Two axis lens holders (LHCM) without focus adjustment function are also available.
W4512-2
▶Two Axis lens holders (LHCM) for lenses φ20mm or less are also available.
▶Please contact our Sales Division if you require a specific optical axis height.

Attention

▶Two spacers are included with these mounts to allow positioning of the lens within the lens tube.
▶When the focal length of lens is long, adjustment does not work effectively because the focus adjustment range is too narrow. In such a case, please use the dovetail stages or optical benches.
