HTMC25-NS Manual Translation Stage with 25 mm Travel, Micrometer Drive, Center-Actuated

Overview

The HTMC25-NS is a precision-engineered manual translation stage designed for stable, repeatable linear positioning in optical alignment, interferometry, microscopy, and laser beam steering applications. Built upon a rigid aluminum alloy base with hardened stainless steel components, it employs high-accuracy linear ball bearing rails to ensure minimal wobble, low hysteresis, and consistent straightness over its full 25 mm travel range. The center-actuated micrometer drive—typically equipped with a 0.5 mm pitch fine-thread screw and integrated 10 µm resolution micrometer head—provides tactile, backlash-free motion control without requiring external power or electronics. Its mechanical architecture follows classical kinematic design principles: three-point support (two preloaded linear rails + center drive point) ensures uniform load distribution and minimizes pitch/yaw deviations during translation.

Key Features

• Precision linear ball bearing guideways with hardened raceways for long-term dimensional stability and sub-micron repeatability
• Center-mounted micrometer drive mechanism eliminates eccentric loading and reduces moment-induced angular error
• Spring-preloaded carriage assembly actively compensates for axial clearance, ensuring zero-backlash operation across repeated cycles
• Standardized mounting pattern (M4 threaded holes on 25 mm grid, M6 at corners) enables modular integration with other stages, kinematic mounts, and optical tables
• Interchangeable drive options: compatible with standard micrometers (e.g., 0–25 mm, 0.01 mm scale), differential micrometers (10× enhanced resolution), or custom fine-pitch lead screws (e.g., 0.25 mm/rev)
• Anodized aluminum body with corrosion-resistant surface finish suitable for cleanroom and laboratory environments

Sample Compatibility & Compliance

The HTMC25-NS is intended for use with optical components up to 1.5 kg static load, including mirrors, lenses, fiber couplers, and detector mounts. Its mechanical interface conforms to common international optical breadboard standards (e.g., Thorlabs, Newport 25 mm hole spacing). While not certified to ISO 9001 or ISO 17025 as a metrology instrument, the stage’s construction adheres to general mechanical tolerancing practices per ISO 2768-mK. It is suitable for use in GLP-compliant laboratories where traceable positioning is required for experimental setup documentation—not for primary calibration or regulatory submission. No electromagnetic emissions or safety certifications (e.g., CE, UL) apply, as the device contains no active electronics or hazardous materials.

Software & Data Management

As a purely mechanical manual stage, the HTMC25-NS requires no firmware, drivers, or software integration. Position readout is achieved via the integrated micrometer scale (graduated in 10 µm increments, with optional vernier estimation to 1 µm). Users may log positional data manually or integrate the stage into larger systems using external encoders (e.g., linear optical encoders mounted separately) if closed-loop feedback is needed. For audit-trail requirements in regulated environments, position records should be entered into laboratory notebooks or LIMS platforms following institutional SOPs—no native electronic logging or FDA 21 CFR Part 11 compliance is provided or implied.

Applications

• Laser cavity alignment and mode-matching optimization in ultrafast and CW laser systems
• Positioning of collimators, retroreflectors, or wavefront sensors in interferometric setups (e.g., Michelson, Mach-Zehnder)
• Coarse/fine adjustment of sample holders in Raman spectroscopy, ellipsometry, and photoluminescence measurement stations
• Integration into multi-axis goniometers or XYZ stacks for beam path manipulation in teaching labs and prototype development
• Calibration reference staging for validating motorized stage linearity and repeatability
• Stable platform for optical component burn-in testing under thermal or vibrational stress conditions

FAQ

What is the typical bidirectional repeatability of the HTMC25-NS?

Under controlled lab conditions (23 °C ±1 °C, no vibration), repeatability is ≤ ±2 µm over 10 consecutive cycles when using the standard micrometer head and proper mounting torque.
Can this stage be vacuum-compatible?

The standard anodized aluminum version is not vacuum-rated; outgassing and lubricant volatility limit use to ambient air only. Vacuum-compatible variants require dry-film lubricants and alternative surface treatments—contact manufacturer for OEM configurations.
Is the micrometer head included with the stage?

Yes—the HTMC25-NS ships with a calibrated 0–25 mm metric micrometer head (0.01 mm resolution) pre-installed and centered on the carriage.
How is angular deviation (pitch/yaw) specified?

Maximum angular deviation over full travel is ≤ 30 arcsec (0.008°) in pitch and ≤ 25 arcsec in yaw, measured per ISO 10360-2 methodology using autocollimation.
Can multiple HTMC25-NS stages be stacked for XYZ motion?

Yes—its standardized footprint and tapped-hole pattern allow direct stacking with compatible base plates or adapter plates. Recommend using locking screws and torque-controlled assembly to maintain orthogonality.
