ZOLIX KSMTW Series Integrated Multi-Axis Translation Stage

Overview

The ZOLIX KSMTW Series Integrated Multi-Axis Translation Stage is an engineered solution for high-precision planar positioning in optical alignment, interferometry, microscopy stage integration, and photonics packaging applications. Unlike stacked or modular multi-axis stages, the KSMTW employs a monolithic mechanical architecture where the upper-axis platform serves directly as the base plate of the lower-axis subsystem—eliminating inter-stage coupling errors, reducing cumulative orthogonality deviations, and minimizing overall footprint without compromising mechanical rigidity. Its motion principle relies on pure linear translation via crossed-roller guideways, ensuring minimal pitch/yaw/roll parasitic motion across the full travel range. Designed for laboratory-grade repeatability and long-term dimensional stability, the stage conforms to fundamental metrological requirements for optical path length control and beam steering calibration workflows.

Key Features

• Monolithic integrated X-Y architecture with co-planar drive mounting—reduces stack height to only 34 mm while maintaining orthogonal alignment within <30 µm parallelism tolerance.
• Imported high-precision crossed-roller linear guides provide low-friction, high-load-capacity motion with exceptional smoothness and service life exceeding 10⁶ cycles under nominal loading.
• Electropolished stainless steel construction (AISI 304 equivalent) ensures dimensional stability across thermal gradients and resistance to oxidation in cleanroom and vacuum-compatible environments (up to 10⁻⁴ Pa with optional surface treatment).
• Dual-spring preloaded anti-backlash mechanism eliminates hysteresis in both X and Y axes, enabling repeatable positioning without manual homing routines.
• Modular drive interface supports either fine-pitch threaded screw actuation (KSMTW-213-231) or calibrated micrometer head integration (KSMTW-213-232), offering resolution flexibility from 1 µm to 0.5 µm per division depending on operator calibration protocol.
• Standardized 40 mm × 40 mm top platform features M3 and M4 tapped holes arranged in ISO 841-compliant grid patterns for direct mounting of lens mounts, fiber couplers, or detector carriers.

Sample Compatibility & Compliance

The KSMTW stage is compatible with standard optical components up to 1.2 kg total payload (centered load). It meets mechanical interface specifications defined in ISO 10110-7 for optical mount compatibility and aligns with dimensional tolerances referenced in ANSI/OPI B1.10M for precision translation devices. While not certified to ISO 9001 at unit level, ZOLIX manufacturing processes comply with ISO 9001:2015 quality management standards. The stage’s material composition and surface finish support use in Class 1000 cleanrooms; vacuum-outgassing testing data (per ASTM E595) is available upon request for space-qualified or UHV deployment scenarios.

Software & Data Management

As a manually operated mechanical stage, the KSMTW does not incorporate embedded electronics or digital feedback. However, it is fully interoperable with third-party motion control ecosystems including Thorlabs Kinesis, Newport APT, and LabVIEW-based DAQ systems when paired with external position sensors (e.g., capacitive probes or laser interferometers). Optional encoder retrofits (e.g., Renishaw RESOLUTE™ linear encoders) can be integrated via custom adapter plates—enabling closed-loop operation compliant with GLP audit trails and FDA 21 CFR Part 11 electronic record requirements when deployed in regulated QC laboratories.

Applications

• Precision alignment of laser diodes, collimators, and fiber arrays in telecom component testing benches.
• Beam walk correction and focus optimization in confocal and multiphoton microscopy setups.
• Active alignment of micro-opto-electro-mechanical systems (MOEMS) during wafer-level packaging.
• Reference stage for calibrating coordinate measuring machines (CMMs) and optical comparators in metrology labs.
• Substrate positioning in thin-film characterization systems using ellipsometry or reflectometry.

FAQ

Is the KSMTW stage suitable for vacuum environments?
Yes—stainless steel construction and absence of lubricants or polymer components enable operation in medium vacuum (10⁻⁴ Pa); bake-out capability up to 80 °C requires optional passivation.
Can I retrofit stepper motor actuators to the KSMTW series?
Yes—standardized 8-32 UNC and M4 mounting interfaces allow mechanical coupling to NEMA 8 or NEMA 11 stepper motors with appropriate bracket kits (ZOLIX P/N: K-MTR-KIT-01).
What is the maximum recommended load for dynamic operation?
1.2 kg static load; for continuous scanning motion, limit to 0.8 kg to maintain <±0.5 µm repeatability over 10⁵ cycles.
Does ZOLIX provide traceable calibration certificates?
Calibration reports per ISO/IEC 17025 are available upon request and include bidirectional travel error mapping using laser interferometry (NIST-traceable reference).
Are left-hand configurations available for all models?
Yes—all KSMTW variants support left-hand orientation (denoted by “L” suffix, e.g., KSMTW-213-232L) with identical mechanical performance and interchangeability.
