The internal threaded alignment disc provided by LBTEK can center visible light with lens tubes or fixed optic mounts. The front side of the alignment disc features X-axis and Y-axis alignment scales to facilitate alignment operations. The back side has SM05, SM1, and SM2 internal threaded structures, compatible with 0.5-inch, 1-inch, and 2-inch lens sleeves or fixed optic mounts.

The external threaded alignment disc provided by LBTEK can center visible light with lens sleeves or fixed optical component mounts. The front side of the alignment disc features X-axis and Y-axis alignment scales to facilitate the alignment process. The back side of the alignment disc has external threaded structures for SM05, SM1, and SM2, compatible with 0.5-inch, 1-inch, and 2-inch lens sleeves or fixed optical component mounts.

LBTEK's externally threaded alignment discs with through holes can center visible light onto lens tubes or fixed optical component mounts; models ending with H1 and H2 feature Ø1 mm and Ø2 mm through holes, respectively, allowing users to pass visible beams through the center of the alignment disc. For optimal visual alignment, these alignment discs have laser-engraved concentric circles ranging from Ø4 mm - Ø12 mm (models starting with TADSM05), Ø4 mm - Ø20 mm (models starting with TADSM1), and Ø8 mm - Ø44 mm (models starting with TADSM2), with each concentric circle's radius 2 mm larger than the previous one (4 mm for models starting with TADSM2); in addition, the back of the alignment discs features SM05, SM1, SM2 external thread structures, compatible with 0.5-inch, 1-inch, and 2-inch lens tubes or fixed optical component mounts; the knurled edge of the alignment disc facilitates hand tightening.
