These alignment targets for visible light help simplify the process of aligning an optical system. All of these targets are made out of anodized aluminum. Each of these targets features either laser-engraved concentric circles, graduated X- and Y-axes, or a single engraved axis for optimal visual alignment of the beam. Options are available for compatibility with cage systems, lens mounts, and lens tubes. For assistance aligning UV or IR light, we offer fluorescing alignment disks and detector cards.
These drop-in alignment plates are convenient tools for aligning visible beams in cage-based optical systems. Made from anodized aluminum, they provide a through hole at the center of the cage assembly. For easy alignment, the through hole is surrounded by engraved alignment rings.
These alignment targets can be quickly and easily dropped onto one of our fixed lens holders or lens tubes allowing the user to align a visible beam using the center Ø1 mm through hole. Once the beam is aligned, the tool can be lifted from the lens holder or lens tube without disturbing the alignment and can later be replaced into approximately the same position.
For optimal visual alignment of the beam, these plates feature laser-engraved concentric circles, with the diameter of each circle being 2 mm greater than the previous. The LMR05AP Alignment Plate has four of these concentric circles and fits Ø1/2" fixed optic mounts and lens tubes, the LMR1AP Alignment Plate has eight concentric circles and fits Ø1" fixed optic mounts and lens tubes, and the LMR2AP Alignment Plate has twelve concentric circles and fits Ø2" fixed optic mounts and lens tubes.
The SM05A7 and SM1A7 alignment disks provide useful aids for aligning visible beams to the center of optical mounts. To enable accurate alignment, the disks have clear markings with graduations on both the X and Y axes. The back of the SM05A7 features our standard SM05 (0.535"-40) threading for compatibility with Ø1/2" lens tubes and fixed optics mounts, while the SM1A7 has SM1 (1.035"-40) threading for compatibility with Ø1" lens tubes and fixed optics mounts.
Aperture Plates are a useful tool for system alignment or to measure beam size. The aperture plate should be mounted into a Ø1/2" optic mount (such as the LMR05, as shown in the image to the right) and then can be used to establish an optical center line in a system. It is also useful for blocking stray light or other unwanted light in an optical system.
