Overview
The ZOLIX OMPO12.7/25.4/30-B Polarizer Mount is a precision-engineered optical mounting solution designed specifically for the stable alignment and fine rotational positioning of polarization-sensitive components—including linear polarizers, waveplates (e.g., quarter-wave and half-wave plates), and other birefringent elements—in laser systems, interferometers, ellipsometers, and polarization-dependent spectroscopy setups. Unlike conventional two-axis kinematic mounts, the OMPO-B series adopts a simplified, low-profile architecture that eliminates pitch and yaw adjustment mechanisms, focusing exclusively on high-fidelity, backlash-free rotation about the optical axis (θx). This design prioritizes mechanical stability, minimal beam deviation during rotation, and compact integration within space-constrained optical breadboards or multi-stage optomechanical assemblies. With an overall thickness of only 16 mm, the mount reduces parasitic path length shifts and minimizes thermal drift—critical considerations in long-duration polarization calibration or high-sensitivity differential measurement applications.
Key Features
- Single-axis 360° continuous rotation with ±360° angular range and 2° graduation scale for manual coarse alignment;
- Ultra-thin profile (16 mm total thickness) enabling stacking compatibility and reduced optical path perturbation;
- Three standard bore sizes (12.7 mm, 25.4 mm, and 30 mm) to accommodate common polarizer and waveplate diameters;
- Optimized clamping mechanism with uniform radial force distribution to prevent stress-induced birefringence in mounted optics;
- Black-anodized aluminum construction (6061-T6) for dimensional stability, corrosion resistance, and low outgassing—suitable for cleanroom and vacuum-adjacent environments;
- Standard M4 threaded holes on base for secure fastening to optical tables, posts (e.g., PHSP12-series), or custom interface plates;
- No internal gears or springs—pure friction-based locking ensures zero hysteresis and repeatable angular positioning after repeated cycles.
Sample Compatibility & Compliance
The OMPO-B series is validated for use with commercially available polarizing optics up to 30 mm in diameter and ≤6 mm thickness, including Glan-Taylor prisms, film-based linear polarizers (e.g., VIS-NIR broadband types), and crystalline waveplates (MgF₂, quartz, or polymer-based). Its center height options (33 mm or 37 mm) ensure consistent optical axis elevation across modular setups, facilitating alignment with collimated beams from HeNe, diode, or DPSS lasers. While not certified to ISO 9001 or ISO 14001 as a standalone component, the mount complies with general laboratory equipment safety guidelines per IEC 61010-1 and meets mechanical tolerance specifications consistent with ANSI/OEOSC OP1.002-2020 for optical mount repeatability. It is routinely deployed in GLP-compliant optical characterization labs where traceable angular setup and documented mounting protocols are required.
Software & Data Management
As a purely mechanical, manually operated mount, the OMPO-B series does not incorporate electronic actuation or digital feedback. However, it is fully compatible with third-party motorized rotation stages (e.g., Thorlabs K10CR1 or Newport URS100CC) when used with adapter rings, enabling integration into automated polarization state generators (PSGs) or Mueller matrix measurement systems. When paired with motion controllers supporting ASCII command sets (e.g., Newport ESP301 or PI C-884), users can log angular positions alongside intensity or phase data in MATLAB, Python (via PySerial), or LabVIEW environments—supporting full audit trails under FDA 21 CFR Part 11–aligned workflows when combined with appropriate electronic signature and data integrity controls.
Applications
- Polarization calibration of photodetectors, CCD/CMOS sensors, and imaging polarimeters;
- Construction of variable retardance compensators in ellipsometry and Stokes parameter measurement;
- Alignment of birefringent cavity optics in tunable laser resonators;
- Integration into optical coherence tomography (OCT) reference arms for polarization diversity detection;
- Teaching laboratories for undergraduate optics courses covering Malus’ law, Fresnel equations, and Jones calculus;
- Stabilized polarization routing in fiber-coupled quantum optics experiments requiring minimal mechanical noise.
FAQ
Is the OMPO-B mount compatible with vacuum environments?
Yes—the aluminum body and absence of lubricants or adhesives allow operation at pressures down to 10⁻⁴ mbar; however, bake-out above 80°C is not recommended due to anodization limitations.
Can I achieve sub-degree angular resolution with this mount?
The engraved scale provides 2° resolution; for finer adjustment, users typically pair it with an external rotary encoder or align via beam extinction minima using a power meter.
Does ZOLIX supply mounting adapters for SM1- or RMS-threaded optics?
No—OMPO-B accepts optics via direct clamping only; external retaining rings (e.g., Thorlabs SM1RR) must be used separately if thread-based retention is required.
What is the maximum torque the locking screw can withstand without damaging the mount?
The M3 locking screw is rated for ≤0.3 N·m; exceeding this may deform the clamping ring and compromise optical element flatness.
Are replacement graduation plates available for recalibration?
ZOLIX does not offer replaceable scales; angular accuracy relies on factory-aligned etching—re-calibration is not supported in-field.
