Overview
The HTSM-25 is a manually operated precision micrometer translation stage engineered for sub-millimeter positional control in optical alignment and metrology applications. Based on the classical micrometer screw principle—where linear displacement is generated via precise rotation of a calibrated threaded spindle—the device delivers deterministic, repeatable motion with mechanical backlash minimized through optimized brass-on-steel thread engagement and integrated spring-loaded preload. Its 25 mm total travel range and 10 µm minimum graduation (0.01 mm) enable fine-tuning of optical components such as mirrors, lenses, fiber couplers, and interferometric reference arms within constrained optical paths. Designed for integration into free-space optical benches and modular optomechanical systems, the HTSM-25 adheres to standard dimensional footprints and mounting hole patterns used across major international optical hardware ecosystems.
Key Features
- High-resolution mechanical translation: 10 µm per scale division, verified by factory calibration traceable to national metrology standards
- Stainless steel body with black anodized aluminum micrometer knob for corrosion resistance and tactile feedback
- Integrated vernier scale for interpolated readings down to ±5 µm typical repeatability (under controlled lab conditions)
- Low-profile, rigid construction (height: 22 mm; base width: 32 mm) minimizing moment arm effects during multi-axis stacking
- Threaded mounting holes (M4 × 0.7 pitch, depth 6 mm) compatible with ISO-standard optical tables and kinematic mounts
- No lubrication required; dry-running brass-steel interface ensures long-term stability without outgassing—critical for vacuum-compatible optical enclosures
Sample Compatibility & Compliance
The HTSM-25 is intended for use with passive optical elements including plano-convex lenses, dielectric mirrors, waveplates, and fiber collimators. It supports payloads up to 1.2 kg when mounted horizontally and 0.8 kg in vertical orientation without measurable hysteresis or creep under static load. The device complies with ISO 10110–7 (optical component mounting interfaces) and meets RoHS 2011/65/EU material restrictions. While not certified for cleanroom Class 100 operation, its non-particulating surface finish and absence of adhesives or polymer seals make it suitable for Class 1000 environments common in university optics labs and R&D cleanrooms. Documentation includes a Certificate of Conformance (CoC) issued by the Jiangsu Provincial Institute of Metrology.
Software & Data Management
As a purely manual mechanical stage, the HTSM-25 does not incorporate electronic sensors or digital readouts. However, it is fully interoperable with third-party position-sensing systems—including capacitive displacement sensors (e.g., Lion Precision C3, Micro-Epsilon capaNCDT), laser interferometers (Keysight 5530), and CCD-based beam centroid trackers—when integrated into automated alignment workflows. Users may log positional data manually or via external DAQ systems compliant with IEEE 1451.2 transducer interface standards. For GLP/GMP-aligned laboratories, handwritten logs or LIMS-integrated entries referencing HTSM-25 serial numbers and calibration dates satisfy audit requirements under ISO/IEC 17025 Clause 6.6.
Applications
- Fine alignment of laser cavity mirrors in CW and pulsed oscillator configurations
- Adjustment of focal plane position in confocal microscopy and OCT sample arms
- Calibration reference stage for verifying resolution limits of optical encoders and piezo actuators
- Thermal drift compensation in Michelson and Mach–Zehnder interferometers (used with differential temperature monitoring)
- Educational demonstration of screw mechanics, gear reduction ratios, and measurement uncertainty propagation
- Positioning of photodetectors and pinholes in spatial filtering setups and Fourier plane analysis
FAQ
Is the HTSM-25 compatible with vacuum environments?
Yes—its all-metal construction, absence of elastomers or adhesives, and low-outgassing surface treatment allow operation at pressures down to 10⁻⁵ mbar when properly baked. Vacuum compatibility must be validated per system-level testing.
Does it include a calibration certificate?
Each unit ships with a manufacturer’s Certificate of Conformance. NIST-traceable calibration certificates are available upon request (lead time: 5 business days).
Can multiple HTSM-25 stages be stacked for XYZ motion?
Yes—standard orthogonal stacking using compatible base plates (e.g., Thorlabs KM100 or Newport UMB3) is supported. Total stack height remains below 85 mm for three-axis configuration.
What is the recommended torque for the micrometer knob?
Maximum specified tightening torque is 0.25 N·m. Exceeding this may deform the thread or compromise graduation line visibility.
