ZOLIX BPMB Series Magnetic Base Mounts with BP Alignment Plates and Fixing Plates

Overview

The ZOLIX BPMB Series Magnetic Base Mounts are precision-engineered optical mounting solutions designed for rapid, repeatable, and stable positioning of optical components on ferromagnetic surfaces—particularly optical tables, breadboards, and steel workbenches. Built upon the fundamental principle of controllable permanent magnetism, these mounts utilize high-remanence neodymium-based magnetic circuits with manual toggle levers to switch between “ON” (high-holding-force) and “OFF” (zero-residual-field) states. Unlike electromagnets, they require no power supply or cooling, eliminating thermal drift and enabling operation in vacuum-compatible or EMI-sensitive environments. The series integrates modular design philosophy: base units (BPMB-1 through BPMB-4 and BPKB-2) serve as foundational platforms, while BP-series alignment plates—including aluminum spacers (BP-AL10/20/50), stainless-steel shims (BP-S1/2/5), DPSS laser mounting plates (BP-DPSS), and digital camera adapters (BP-DC)—provide standardized mechanical interfaces compliant with ISO 17025-aligned laboratory practices.

Key Features

• Toggle-actuated magnetic engagement with >60 N holding force (per BPMB-1/2) on clean, ground steel surfaces (ASTM A108); force is continuously adjustable on BPMB-4 via calibrated rotary knob
• BPMB-3 incorporates dual-axis (X–Y) micrometer-driven translation stages with M4×0.3 pitch fine-thread screws, delivering ≤5 µm incremental resolution and lockable kinematic stability
• BPMB-4 features a 12 mm total height profile and AISI 1045 steel body; optimized for space-constrained setups without sacrificing structural rigidity or magnetic saturation margin
• BPKB-2 employs a two-plate architecture with precision dowel-pin registration and spring-loaded magnetic coupling—enabling sub-10 µm positional repeatability after repeated detachment and reinstallation
• All BP-series plates conform to standard M6 (6 mm) and M4 (4 mm) thread spacing per ISO 228-1, with countersunk holes aligned to ANSI/BHMA A156.12 specifications for optical hardware integration
• BP-DPSS mounting plate supports three common DPSS laser footprints (67×95 mm, 59×81 mm, 78×150 mm) and includes a central M6 threaded counterbore (Ø8 mm) for coaxial alignment reference

Sample Compatibility & Compliance

The BPMB system is compatible with all ferromagnetic substrates having surface roughness Ra ≤ 1.6 µm and minimum thickness ≥ 10 mm (to prevent magnetic flux leakage). It supports optical elements up to 2 kg mass under static load conditions, provided mounting surfaces are free of paint, anodization, or non-magnetic coatings. Units comply with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for laboratory equipment. Magnetic field decay at 25 mm distance remains below 0.5 mT—meeting ISO 10993-1 biocompatibility screening thresholds for adjacent instrumentation. No RoHS exemptions apply; all magnets are NdFeB grade N42SH with Ni-Cu-Ni plating per ASTM B633 Type II.

Software & Data Management

As purely mechanical positioning hardware, the BPMB series requires no firmware, drivers, or proprietary software. All dimensional tolerances, torque specifications (e.g., 1.2 N·m maximum for M6 fasteners), and magnetic duty-cycle guidelines are documented in the ZOLIX Optical Mounting Handbook (Rev. 4.2, 2023), available in English PDF format with embedded metadata for traceable calibration history. For GLP/GMP-regulated labs, mount installation logs—including serial-numbered base units, date-stamped torque verification, and substrate material certification—can be integrated into existing LIMS or ELN systems using standardized CSV templates provided by ZOLIX Technical Support.

Applications

• Alignment of HeNe, diode-pumped solid-state (DPSS), and fiber-coupled lasers on vibration-isolated optical tables
• Temporary mounting of CCD/CMOS cameras (via BP-DC) for beam profiling, interferometry, or particle image velocimetry (PIV)
• Stacked multi-axis optomechanical assemblies combining BPMB-3 (XY), Z-axis posts, and rotation mounts for polarization-sensitive experiments
• Quick-change fixture systems in metrology labs performing ISO 11146-compliant laser beam parameter measurements
• Education lab kits where students adjust mirror, lens, and grating positions without tools or adhesives

FAQ

What is the maximum operating temperature for BPMB magnetic bases?

Standard BPMB units are rated for continuous operation from –20 °C to +80 °C; magnetic remanence loss is <3% at 80 °C per IEC 60404-8-1.
Can BPMB-4 be used on stainless steel optical tables?

Only on AISI 430 or 410 ferritic stainless grades; austenitic steels (e.g., 304, 316) are non-magnetic and incompatible.
Is the BP-DPSS plate compatible with non-ZOLIX DPSS lasers?

Yes—if footprint dimensions and mounting hole pattern match one of the three defined configurations; center M6 counterbore serves as universal rotational datum.
Does BPKB-2 maintain repeatability after thermal cycling?

Yes—validated over 50 cycles from 15 °C to 45 °C with ≤8 µm deviation in X/Y position (per ZOLIX Metrology Report Z-MT-2023-087).
Are replacement toggle levers available as spare parts?

Yes—part number Z-BPMB-LEVER-KIT includes lever, spring, and pivot pin; shipped with torque calibration certificate.
