B Series Lens Mount Barrels
B Series Lens Mount Barrels are used for mounting simple lenses and achromatic doublet lenses to protect them from possible damage. These lens barrels can be integrated into an optical system by mounting them in SB or CB Series Lens Barrel Holders. The lens barrels consist of a threaded body and a retaining ring; when screwed together, the lens is securely held in place. For thick lenses, the retaining ring is reversible. Two or more lens barrels can be threaded end-to-end to construct simple optical systems.
Lens barrels for 6.35 and 12.7 mm diameter lenses have a M20.25 RMS thread on the outside diameter for mounting into B18 Series Lens Mount Barrels. The B20-RMS Focusing Barrel allows axial translation of an optic over 5 mm by turning the knurled knob. The B25.4-RT Rotation Barrel allows 360° rotation of an optic with 2° graduations. The B25.4-F Barrel allows 25.4 mm diameter mirrors or lenses to be mounted to M20.25 RMS-threaded components.
