Overview
The HTFPS301R is a right-handed, three-axis precision fiber optic positioning mount engineered for sub-micron spatial control in demanding optical alignment applications. Designed around the principles of kinematic stability and thermal drift suppression, it employs a rigid monolithic stainless steel body—selected for its low coefficient of thermal expansion (CTE ≈ 17.3 × 10⁻⁶ /°C)—to minimize positional drift under ambient temperature fluctuations. Its core motion architecture integrates high-grade crossed roller bearings with precision-lapped V-groove guides, enabling smooth, backlash-free translation along X, Y, and Z axes with angular repeatability better than ±1.5 arcsec per adjustment revolution. The mount conforms to standard optical breadboard mounting interfaces (M4 and 1/4″-20 tapped holes), supporting integration into laser interferometry setups, free-space-to-fiber coupling systems, and quantum optics testbeds where long-term pointing stability and mechanical hysteresis < 0.05% are critical.
Key Features
- Right-handed ergonomic configuration optimized for intuitive operation in right-dominant lab environments and dual-mount symmetry with HTFPS301L (left-handed counterpart)
- Stainless steel construction with passivated surface finish for corrosion resistance and dimensional stability across 15–30 °C operational range
- Crossed roller bearing mechanism paired with hardened, ground V-grooves ensures linear travel resolution down to 0.5 µm per fine-thread knob revolution (100 TPI)
- Compact footprint (72 mm × 62 mm × 38 mm) enables dense arrangement on optical tables without compromising access or clearance
- Integrated dovetail base (8 mm wide, 30° angle) compatible with industry-standard kinematic clamps and modular rail systems
- Zero-backlash micrometer-style actuators with knurled aluminum knobs provide tactile feedback and consistent torque transmission
Sample Compatibility & Compliance
The HTFPS301R accommodates standard Ø1.25 mm, Ø2.5 mm, and Ø5.0 mm ferruled single-mode and multimode fibers (including FC/PC, SC/APC, and LC connectors) via optional adapter sleeves. It supports fiber collimators up to 25 mm clear aperture and objective lenses with ≤30 mm outer diameter. While not certified to ISO 9001 or EN 1090 by the distributor, the mount’s mechanical design adheres to common laboratory-grade tolerancing practices aligned with ISO 2768-mK general tolerances. Its material composition and surface treatment comply with RoHS Directive 2011/65/EU for restricted hazardous substances. No regulatory certification (e.g., FDA, CE marking) applies, as it is classified as a passive optical mechanical component—not an active or medical device.
Software & Data Management
As a purely manual, non-motorized positioning system, the HTFPS301R requires no firmware, drivers, or software interface. All adjustments are performed mechanically using calibrated micrometer dials; position tracking must be implemented externally via integrated optical encoders (e.g., Thorlabs KPA101), laser Doppler vibrometers, or camera-based centroid analysis tools. For traceable alignment workflows, users may log positional settings manually or integrate with LabVIEW or Python-controlled motorized stages via third-party motion controllers when used in hybrid optomechanical assemblies. Audit trails for calibration records fall under user-defined GLP/GMP documentation protocols—not embedded functionality.
Applications
- Precise alignment of single-mode fiber pigtails to laser diodes, photonic integrated circuits (PICs), and waveguide facets
- Active stabilization loops in heterodyne interferometers and cavity ring-down spectroscopy (CRDS) platforms
- Beam steering and focus optimization in confocal microscopy and optical coherence tomography (OCT) source coupling
- Thermal drift compensation studies in ultra-stable optical cavities and atomic physics experiments (e.g., magneto-optical traps)
- Education and training in undergraduate photonics labs for teaching fundamentals of optical alignment, degrees of freedom, and error budgeting
FAQ
Is the HTFPS301R compatible with vacuum environments?
No—standard version uses lubricated crossed roller bearings and non-outgassing seals unsuitable for UHV (<10⁻⁶ mbar). Vacuum-compatible variants require custom dry-film lubrication and stainless steel grade 316L construction.
Can left- and right-handed units be mounted side-by-side for differential motion?
Yes—the HTFPS301R and HTFPS301L share identical mounting hole patterns and height profiles, enabling symmetric XYZ stage pairing with independent axis control.
What is the maximum load capacity at full extension?
The mount maintains ≤1.0 µrad angular deviation under static loads up to 1.2 kg when centered on the base; lateral loading exceeding 0.3 kg at maximum Z-travel may induce elastic deformation beyond specification limits.
Are replacement V-groove inserts or bearing kits available?
Yes—HT offers service kits including matched V-groove rails (part #HT-VG301-R), preloaded crossed roller cartridges (HT-CR301), and recalibration certificates upon request.
