The Sliding Filter Mount SFM1 provided by LBTEK comes with two SFM1-A inserts, allowing for the setup of up to four Ø25.4 mm optical components. The SFM1-A inserts can be purchased separately. The inserts and main body are positioned via steel balls and V-grooves plus dovetail tracks, with locking screws on top to secure them after positioning. The bottom features M4 threaded holes for connecting to optical posts. The main body has eight M3 threaded holes for compatibility with 30 mm coaxial systems. The cover plate includes four M2.5 threaded holes for stacking mounts.

LBTEK offers Sliding Filter Inserts with dual SM1 threads for mounting optical components of Ø25.4 mm and a maximum thickness of 6 mm. Multiple inserts can be stacked, and when two inserts are connected vertically, they can be hooked together. The spring-loaded detent mechanism keeps the two inserts parallel. When used in with the SFM1 main body, it enables rapid switching of optical components.
