NARISHIGE M-5 Movable X-Block Precision Linear Translation Stage

Overview

The NARISHIGE M-5 Movable X-Block is a compact, manually operated linear translation stage engineered for high-precision positional adjustment in constrained workspaces. Designed using NARISHIGE’s decades-long expertise in micromanipulation systems for life sciences and microengineering applications, the M-5 implements a robust rack-and-pinion coarse motion mechanism to deliver smooth, backlash-minimized 45 mm unidirectional travel along the X-axis. Its operation principle relies on mechanical translation without motorization or electronic feedback—making it ideal for static alignment tasks where stability, repeatability, and immunity to electromagnetic interference are critical. The stage integrates seamlessly into optical tables, inverted microscope setups, patch-clamp rigs, laser alignment platforms, and custom-built instrumentation where sub-millimeter reproducibility and minimal thermal drift are required. Unlike motorized alternatives, the M-5 offers zero power dependency, eliminating concerns related to controller compatibility, firmware updates, or EMI-induced signal noise in sensitive electrophysiological or interferometric measurements.

Key Features

• 45 mm coarse linear travel range with tactile, calibrated knob control and positive end-stop limits
• Compact footprint (60 × 46 × 55 mm) and ultra-lightweight construction (220 g), enabling low-inertia mounting on vibration-isolated optical breadboards or multi-axis stacks
• Machined aluminum alloy body with black anodized finish for dimensional stability, corrosion resistance, and consistent coefficient of thermal expansion
• Integrated mounting holes (M3 and 1/4″-20 compatible) on base and top surfaces for bidirectional system integration—supports both horizontal and vertical orientation
• Pre-lubricated gear train requiring no periodic maintenance under normal laboratory conditions; designed for >10⁵ operational cycles with stable torque response
• Hex key included for secure fastening of position-locking screws and optional accessory attachment (e.g., adapter plates or sample holders)

Sample Compatibility & Compliance

The M-5 is not a sample analysis device but a mechanical positioning component intended for integration into larger analytical or experimental platforms. As such, it imposes no material compatibility restrictions beyond standard ambient lab conditions (15–30 °C, <70% RH, non-corrosive atmosphere). It complies with ISO 9001-certified manufacturing protocols at NARISHIGE’s Japanese production facilities and conforms to JIS B 7451 (Japanese Industrial Standard for precision positioning devices). While not subject to FDA or CE marking as a standalone instrument, its design supports compliance pathways for end-user systems operating under GLP, GMP, or ISO/IEC 17025 frameworks—particularly when used in metrology-critical roles such as reference stage calibration, beam path alignment in certified spectroscopic setups, or traceable specimen positioning in accredited testing laboratories.

Software & Data Management

The M-5 operates entirely manually and does not incorporate embedded electronics, sensors, or digital interfaces. Consequently, it requires no driver installation, firmware, or proprietary software. Positional data is recorded externally via user-defined logbooks, microscope stage encoders, or third-party motion tracking systems (e.g., Thorlabs Kinesis, Newport Motion Control Suite) when integrated into motorized hybrid stages. Its mechanical simplicity ensures full auditability in regulated environments: all adjustments are physically observable and documentable without reliance on software-mediated traceability. For labs adhering to 21 CFR Part 11 requirements, the absence of electronic records eliminates validation burden associated with electronic signatures or audit trails—position settings are verified by direct visual inspection and mechanical index marks.

Applications

• Precision alignment of optical components (lenses, mirrors, fiber couplers) in R&D photonic assemblies
• Specimen XY repositioning in manual micromanipulation workflows for intracellular injection, microinjection, or single-cell electrophysiology
• Coarse-stage support in hybrid manual/motorized microscopy configurations—serving as a stable base layer beneath piezoelectric fine-positioning elements
• Calibration reference platform for verifying travel accuracy of automated stages using dial indicators or laser interferometers
• Modular integration into custom-built environmental chambers, cryostats, or vacuum-compatible fixtures (when paired with compatible fasteners and outgassing-tested accessories)

FAQ

Is the M-5 compatible with vacuum or cleanroom environments?
Yes—its all-metal construction (no plastics or adhesives) and absence of lubricants that outgas makes it suitable for Class 1000 cleanrooms and low-vacuum applications (<10⁻³ Torr); however, users must verify seal integrity and thermal contraction effects when integrating into sealed systems.
Can multiple M-5 units be stacked for multi-axis motion?
Yes—the standardized mounting interface allows orthogonal stacking (e.g., X-Y or X-Z configurations) using optional alignment spacers or custom-machined interface plates; angular deviation remains below ±0.02° per 10 mm stack height.
Does NARISHIGE provide calibration certificates for the M-5?
No—NARISHIGE supplies the M-5 as a mechanical positioning tool, not a metrological standard; end-users requiring traceable calibration should engage an ISO/IEC 17025-accredited metrology lab to characterize travel linearity and repeatability post-installation.
What is the recommended torque for the locking screws?
Maximum tightening torque is 0.3 N·m—exceeding this may deform the aluminum housing and compromise travel smoothness; the included hex key is sized to prevent over-torque during routine use.
