ZOLIX TSMV60/120-1S Heavy-Duty Scissor-Lift Translation Stage

Overview

The ZOLIX TSMV60/120-1S is a precision-engineered heavy-duty scissor-lift translation stage designed for stable, repeatable vertical positioning in optical laboratory environments. Unlike conventional linear actuators or motorized stages, this mechanical lift stage employs a kinematically optimized scissor linkage architecture—combined with precision ground lead screw actuation—to deliver high rigidity, minimal parasitic motion (e.g., tilt, yaw, or lateral shift), and exceptional load-to-weight ratio. Its core function is coarse-to-fine vertical adjustment over extended travel ranges (60 mm or 120 mm), making it particularly suitable for applications requiring frequent manual repositioning of optical components—such as lenses, mirrors, detectors, or fiber couplers—within multi-axis optical benches, interferometric setups, or custom optomechanical assemblies. The stage operates on pure mechanical principles with no electronics, eliminating electromagnetic interference (EMI) concerns and ensuring long-term stability under static or quasi-static loading conditions.

Key Features

• Scissor-linkage mechanism with five-axis over-constrained dual-rail guidance (TSMV60-1S) or six-rail reinforced guidance (TSMV120-1S), engineered to suppress rotational error motions and maintain parallelism throughout full travel.
• Precision ground single-threaded lead screw (TSMV60-1S) or dual-directional (left/right-hand) lead screw (TSMV120-1S), enabling backlash-free, self-locking motion and fine manual control at 0.01 mm resolution.
• Dual-sided mounting surface featuring standardized M4 and M6 threaded hole patterns (ISO metric), allowing flexible integration as either top-stage platform or base-level support—ideal for stackable or inverted configurations.
• Integrated locking knob with positive mechanical engagement, providing secure position retention without creep under rated static load (up to 25 kg).
• Low-inertia aluminum alloy construction with hard-anodized finish, balancing structural stiffness, thermal dimensional stability, and corrosion resistance in controlled lab environments.
• No external power, controllers, or cables required—fully compatible with ultra-high vacuum (UHV)-compatible modifications and EMI-sensitive instrumentation such as photomultiplier tubes, lock-in amplifiers, or low-noise CCD readout systems.

Sample Compatibility & Compliance

The TSMV60/120-1S is compatible with standard optical components conforming to ISO 10110 and DIN 4760 dimensional tolerances, including Ø25.4 mm and Ø50.8 mm lens mounts, kinematic mirror cells, and SM1/SM2-threaded accessories. Its non-magnetic aluminum body meets RoHS Directive 2011/65/EU requirements. While not certified to specific ISO or ASTM standards as a standalone device, its mechanical design adheres to fundamental principles outlined in ISO 9283 (manipulator performance testing) and supports compliance workflows in GLP/GMP-aligned laboratories when integrated into validated optical alignment procedures. No hazardous substances are used in manufacturing per REACH Annex XIV.

Software & Data Management

This is a manually operated mechanical stage with no embedded electronics, firmware, or digital interface. Consequently, it does not require drivers, SDKs, or software integration. Position tracking must be performed externally using calibrated height gauges, dial indicators, or laser interferometers (e.g., Keysight 5530 or Zygo ZMI series). For labs implementing 21 CFR Part 11–compliant documentation, manual position entries can be recorded within ELN systems (e.g., LabArchives or Benchling) alongside timestamped operator signatures and audit trails.

Applications

• Vertical coarse alignment of collimators and beam expanders in laser cavity setup and maintenance.
• Elevation adjustment of sample holders in Raman spectroscopy, fluorescence microscopy, or ellipsometry platforms.
• Height tuning of detector arrays or photodiode mounts relative to focal planes in custom optical train assemblies.
• Modular stacking in multi-level optical breadboard systems where thermal drift compensation is achieved via symmetric mechanical design rather than active feedback.
• Support structure for vacuum-compatible viewports or feedthrough-mounted optics where electrical isolation and zero EMI emission are mandatory.

FAQ

Is the TSMV60/120-1S compatible with motorized actuation?
No—the stage is designed exclusively for manual operation via the integrated lead screw knob. Retrofitting with stepper or servo motors would compromise structural integrity and void factory calibration; ZOLIX does not supply motorized variants of this model.
Can it be used in vacuum environments?
Yes, with appropriate material verification and outgassing preconditioning. The anodized aluminum body and stainless steel fasteners are vacuum-compatible; however, lubricants used in the lead screw assembly must be substituted with dry-film or UHV-grade alternatives prior to chamber insertion.
What is the maximum allowable off-center load?
For optimal lifetime and motion fidelity, eccentric loading should not exceed 30% of total rated capacity and must remain within the central 50% of the top plate area to avoid moment-induced binding or rail wear.
Does ZOLIX provide mounting brackets or adaptors?
Standard M4/M6 mounting hardware is included; optional dovetail adapters, post holders (e.g., PH3, PH6), and cage-system interfaces (e.g., 30 mm or 60 mm cage plates) are available separately under ZOLIX’s optical mounting accessories catalog.
How often does maintenance require lubrication?
Under typical lab use (≤50 cycles/week), re-lubrication of the lead screw is recommended every 12 months using a small quantity of Klüber Isoflex LDS 18 special grease—applied only to the exposed thread section after cleaning residual dust or debris.
