Overview
The Orient KOJI SMP-1218C Optical Platform is a precision-engineered passive vibration isolation platform designed for demanding optical alignment, interferometry, laser cavity construction, and micro-optical assembly applications. It operates on the principle of low-frequency mechanical decoupling—leveraging a high-stiffness, low-mass honeycomb core sandwiched between rigid stainless steel faceplates to suppress broadband environmental vibrations (e.g., floor-borne footfall, HVAC-induced resonance, and acoustic excitation). Its high-permeability 304-type stainless steel top plate enables stable magnetic mounting of kinematic stages, translation mounts, and optical carriers without mechanical clamping—critical for rapid reconfiguration in R&D labs and metrology environments. The platform’s flatness specification (≤0.05 mm/m²) and surface roughness (≤0.8 µm) meet ISO 10360-2 geometric tolerance benchmarks for Grade 0 optical work surfaces, ensuring repeatable positioning accuracy for sub-micron alignment tasks.
Key Features
- 6 mm-thick high-permeability stainless steel top plate with brushed satin finish—optimized for magnetic retention and minimal thermal drift
- Precision-machined M6 threaded mounting holes on a 25 mm grid (standard); optional 50 mm or 100 mm pitch configurations available per customer specification
- Countersunk through-holes eliminate burrs and ensure flush fastener seating—reducing mechanical stress on mounted components
- Honeycomb-core structural architecture fabricated from medium-carbon steel delivers high rigidity-to-weight ratio (>120 GPa effective modulus) and minimizes resonant amplification
- Vertically tuned natural frequency range of 2.5–8 Hz—effectively attenuates >90% of ambient vibrations above 10 Hz per ISO 20486-1 transmissibility curves
- Electrostatically applied matte black powder coating provides ESD-safe, non-reflective surface finish; custom RAL colors supported upon request
Sample Compatibility & Compliance
The SMP-1218C accommodates standard optical components including mirror mounts (e.g., Thorlabs KM100, Newport U100), translation stages (e.g., Standa 8MTF series), fiber launch systems, and compact laser diode modules. Its magnetic compatibility supports direct attachment of ferromagnetic baseplates, eliminating the need for adhesive bonding or mechanical clamps that may induce stress birefringence in sensitive optics. While not an active isolation system, the platform conforms to ISO 14644-1 Class 8 cleanroom handling protocols when used with appropriate gloves and lint-free wipes. Its static load capacity exceeds 150 kg (uniformly distributed), supporting multi-axis optomechanical assemblies typical in university quantum optics labs and industrial laser processing validation setups.
Software & Data Management
As a passive mechanical platform, the SMP-1218C requires no firmware, drivers, or software integration. However, its dimensional stability and flatness repeatability support traceable calibration workflows compliant with ISO/IEC 17025:2017 requirements for measurement uncertainty propagation. When deployed in GLP/GMP-regulated environments (e.g., pharmaceutical laser-based particle sizing validation), documentation of platform certification—including flatness verification reports, material certificates of conformance (EN 10204 3.1), and surface finish test records—can be provided upon order. No electronic logging or audit trail functionality is embedded, consistent with Class I passive laboratory equipment per FDA 21 CFR Part 11 definitions.
Applications
- Laser interferometer alignment and stabilization in gravitational wave prototype experiments
- Fiber optic collimator and isolator assembly requiring sub-5 µrad angular stability
- Confocal microscopy stage integration where mechanical coupling must remain below 0.5 nm RMS displacement
- Education-focused optics teaching labs—supporting hands-on diffraction, polarization, and holography experiments
- Calibration of optical encoders and autocollimators under ISO 230-6 motion accuracy standards
- Hybrid opto-mechanical packaging for photonic integrated circuit (PIC) testing fixtures
FAQ
Is the SMP-1218C compatible with vacuum environments?
No—it is designed for ambient atmospheric use only; stainless steel grade and coating are not UHV-rated.
Can I request NIST-traceable flatness certification?
Yes—third-party metrology reports (per ISO 10360-2 Annex B) are available at additional cost.
What is the maximum recommended payload for dynamic loading conditions?
For vibrational stability under pulsed laser operation (<100 Hz modulation), keep dynamic loads below 40 kg.
Does Orient KOJI supply compatible leveling feet or pneumatic isolators?
Yes—customizable isolation legs (passive elastomeric or active pneumatic) can be quoted separately.
Are M6 thread depths standardized across all hole positions?
Yes—all threaded holes feature 8 mm minimum engagement depth with Class 6H tolerance per ISO 965-1.
