Overview
The ZOLIX EMR Series Rectangular Optical Mounts are precision-engineered kinematic platforms designed for stable, repeatable alignment of rectangular and square optical components in demanding laboratory and industrial optical systems. Constructed from aerospace-grade 6061-T6 aluminum alloy and finished with sandblasted black anodization, each mount delivers high dimensional stability, corrosion resistance, and low thermal expansion—critical attributes for interferometric setups, laser cavity alignment, spectroscopic instrumentation, and free-space optical interconnects. The EMR series implements a dual-stage adjustment architecture: fine angular control via calibrated differential micrometer screws (M4×0.25 or M6×0.25 thread pitch), coupled with robust lever-actuated locking mechanisms that preserve alignment under mechanical vibration or thermal cycling. Unlike cantilever-style mounts, the EMR’s symmetrical bilateral support geometry minimizes torsional deflection during adjustment, ensuring sub-arcminute repeatability over extended operational lifetimes.
Key Features
- Two-axis (pitch/yaw) and three-axis (pitch/yaw + Z-translation) configurations available to accommodate diverse alignment workflows—from coarse initial positioning to nanoradian-level fine-tuning.
- Precision-machined 6061-T6 aluminum body with sandblasted black anodized surface (hardness ≥60 HV, thickness 15–25 µm), providing uniform wear resistance and EMI shielding compatibility.
- Top-access set-screw clamping system with hardened stainless steel tips ensures secure, non-marring fixation of optics ranging from 3 mm to 4 mm minimum thickness—ideal for thin-film filters, polarizers, waveplates, and custom-shaped substrates.
- Calibrated angular resolution options: 0.78°/rev (M4×0.25), 0.39°/rev (M6×0.25), or 0.25°/rev (M6×0.25 with extended travel)—enabling traceable alignment adjustments compatible with ISO 10110-7 and ANSI/OEOSC OP1.002 metrology standards.
- Dual mounting interface options: M4 threaded holes (for bolt-down rigidity) or M4 counterbored holes (for flush surface mounting on breadboards or optical tables), supporting both left-hand and right-hand coordinate conventions.
- Integrated stainless steel return springs (2 or 4 units, model-dependent) maintain consistent preload on adjustment screws, reducing hysteresis and enhancing long-term zero-point stability.
Sample Compatibility & Compliance
The EMR series accommodates standard rectangular optical elements up to 50.8 mm in height—including 12.7 mm (0.5″), 25.4 mm (1″), and 50.8 mm (2″) nominal profiles—with dedicated models for each dimension. Each mount is validated for use with fused silica, BK7, CaF₂, and sapphire substrates within ambient temperature ranges of 15–30 °C and relative humidity ≤60%. All hardware complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. While not certified to ISO 9001 at the component level, ZOLIX manufacturing processes adhere to ISO 9001:2015 quality management principles, and full material certifications (mill test reports) are available upon request for GMP or GLP-regulated applications.
Software & Data Management
As a passive mechanical alignment platform, the EMR series requires no firmware, drivers, or proprietary software. Its design supports integration into automated alignment workflows via third-party motion controllers (e.g., Thorlabs Kinesis, Newport APT) when paired with optional motorized actuators (not included). Angular position data can be logged externally using digital inclinometers (e.g., Spectra Physics 1000-series) mounted adjacent to the adjustment screws. For audit-trail compliance in regulated environments (e.g., FDA 21 CFR Part 11), users may record manual adjustment logs—including operator ID, timestamp, screw rotation count, and final angular reading—in standardized SOP templates aligned with ISO/IEC 17025 documentation requirements.
Applications
- Laser resonator mirror alignment in CW and pulsed solid-state lasers (Nd:YAG, Ti:Sapphire, fiber-coupled diodes)
- Beam steering and collimation of non-circular beams in OCT, LIDAR, and structured-light projection systems
- Mounting of wire-grid polarizers, dichroic mirrors, and multi-layer interference filters in hyperspectral imaging engines
- Stabilized optical pathlength tuning in Michelson and Mach-Zehnder interferometers
- Alignment of micro-optical arrays and diffractive optical elements (DOEs) in photolithography and beam shaping subsystems
- Integration into vacuum-compatible optical benches (with optional vacuum-rated hardware kits)
FAQ
What optical element thicknesses are supported?
The EMR series supports minimum optic thicknesses of 3 mm (for 12.7 mm-height models) and 4 mm (for 25.4 mm and 50.8 mm-height models), ensuring sufficient clamping margin without substrate deformation.
Can these mounts be used in vacuum environments?
Standard EMR mounts are suitable for low-vacuum applications (<10⁻² mbar); for ultra-high vacuum (UHV) use, specify vacuum-compatible anodization (Type III hardcoat) and substitute stainless steel fasteners—available as custom-order options.
Is angular calibration traceable to NIST standards?
While the mounts themselves are not individually calibrated, the M4×0.25 and M6×0.25 leadscrews conform to ISO 2904 (metric screw threads) and exhibit ≤0.02° backlash under 0.5 N·m torque—enabling user-performed calibration against autocollimators or electronic theodolites per ISO 10110-7 Annex B.
How is handedness defined for left-hand vs. right-hand models?
Handedness refers to the orientation of the pitch/yaw adjustment screws relative to the optic plane: right-hand models feature clockwise-tightening screws when viewed from the optic side; left-hand models reverse this convention to accommodate mirrored optical layouts.
Are replacement springs or screws available separately?
Yes—ZOLIX supplies M4 and M6 stainless steel set screws, 2 mm hex socket wrenches, and custom-tension return springs (part numbers EMR-SPR-2X and EMR-SPR-4X) through authorized distribution channels with lead times under 5 business days.
