The LBTEK filter holder is ideal for securing flat optical elements up to 2 mm thick within opto-mechanical assemblies, making it a perfect choice for mounting filters or test targets. The holder uses a spring clip to clamp the flat optical element. To install, loosen the clip screw, insert the element, and gently retighten the screw to secure it. The surface of the spring clip is coated with nylon to prevent damage to the optical element.
The LBTEK compact filter holder OT-CF3 is designed for dual-sided clamping of flat optical elements. The clamping surfaces are coated with nylon, providing secure holding force while preventing damage to the optics. The holder supports optics up to 2 mm thick on a single side, or up to 1.5 mm thick on both sides simultaneously. With its compact size and slim profile, the holder is well-suited for use in space-constrained optical setups. A central M4 threaded hole at the base allows direct mounting onto optical posts.
