These vertical holders are ideal for small spacers due to their thin design and vertical adjustment. Holders can be positioned close to each other reducing optical system size.

◦There are two types, one is fitted with knobs on top (BSHL-2), and the other is without knobs and adjusted by hex wrench (BSHL-TF).
◦This product provides large clear aperture of transmitted beam even if beamsplitter is placed at 45 degrees.
◦The gimbal design maintains the center position of mirror even when fine adjusted.
◦Adjustment screws can be fixed with the clamp screws on the back of the mounts.
◦Two M4 mounting holes are also provided on both sides to mount the holder horizontally.
