The LBTEK Optical Delay Line Mirror Mount is a versatile fixture for optical delay applications, featuring two orthogonal surfaces for mounting standard mirrors. The LBTEK Optical Delay Line Mirror Mount Kit includes the ADM mirror mount and APM3-1 platform mount, which are connected via M4 screws and can be quickly assembled/disassembled using the included hex wrench. Each clamping plate of the ADM mount contains two thumb screws, two springs, and two plastic rods for securing optical component. The mount features two precision-machined mounting surfaces to ensure standard mirrors are positioned at an exact 90-degree angle to each other, enabling input beams to undergo optical delay through dual reflection while maintaining parallel output. The APM3-1 platform mount provides ±4° pitch/yaw adjustment via three M6×0.25 fine-thread screws with adjustment precision 0.4°/rotation. M4 holes secure the platform onto the optical post.
