Accessories and extensions for the main bracket DMAS

LBTEK mounting arm, used to install the objective lens mount onto a manual focusing stage. The objective lens mounting hole on the arm features a φ38.2 mm female dovetail, compatible with five-objective lens mounts, dual-objective lens mounts, and single-objective lens mounts (requires a dovetail adapter for use). The magnet on the upper part of the mounting arm is used to attach the light-blocking bellows on the main bracket with epi-illumination arm, forming a light-tight optical path between the mounting arm and the epi-illumination arm to prevent interference from external light.
