Overview
The HTSB-B Base Plate is a precision-machined structural component designed for stable integration and alignment of optical elements within laboratory-scale optical benches and modular optomechanical systems. Engineered from high-grade anodized aluminum alloy (6061-T6), it serves as a foundational mounting platform compatible with standard 1/4″-20 and M6 threaded holes arranged on a 25 mm grid pattern—adhering to widely adopted optomechanical interface standards used across Thorlabs, Newport, and Standa-compatible hardware ecosystems. Its primary function is mechanical stabilization: minimizing parasitic vibrations, thermal drift, and misalignment-induced beam walk-off during static or quasi-static optical experiments—including interferometry, spectroscopy alignment, laser cavity construction, and polarization-sensitive setups. Unlike passive support plates, the HTSB-B incorporates chamfered edges, countersunk mounting holes, and surface flatness controlled to ≤15 µm over 300 mm, ensuring repeatable kinematic coupling with translation stages, rotation mounts, and lens holders.
Key Features
- High dimensional stability: Aluminum 6061-T6 substrate with thermal expansion coefficient of 23.6 × 10⁻⁶ /°C, suitable for ambient-lab environments (18–25°C)
- Standardized hole pattern: 25 mm pitch grid with dual-thread compatibility (1/4″-20 UNC and M6 × 1.0) for universal accessory interoperability
- Surface finish: Hard-anodized (Type II, 20–25 µm thickness) for enhanced wear resistance and electrical insulation
- Tolerance control: Machined to ±0.05 mm positional accuracy for hole centers; surface flatness certified per ISO 1101 (≤15 µm over full plate area)
- Modular scalability: Designed to interlock with adjacent HT-series base plates via side-mounting slots, enabling custom-sized optical tables without welding or adhesives
Sample Compatibility & Compliance
The HTSB-B is not a measurement device but a mechanical infrastructure component; therefore, it carries no intrinsic sample interaction or regulatory compliance requirements. However, its material composition and manufacturing process comply with RoHS Directive 2011/65/EU (lead-free anodization, halogen-free machining coolants). When integrated into larger optical systems deployed in regulated environments—such as ISO/IEC 17025-accredited calibration labs or GLP-compliant pharmaceutical analytical setups—the plate contributes to overall system traceability by enabling reproducible mechanical registration. It supports mounting of components conforming to ANSI/OEOSC OP1.002 (optomechanical interface standards) and is routinely deployed alongside instruments meeting IEC 61000-4-2 (ESD immunity) and IEC 60950-1 (safety of laser equipment enclosures).
Software & Data Management
As a passive mechanical component, the HTSB-B does not incorporate embedded electronics, firmware, or software interfaces. No drivers, configuration utilities, or data logging capabilities are associated with this part. Its role in digital workflows is limited to geometric referencing within CAD-based optical design environments (e.g., Zemax OpticStudio, FRED, or SolidWorks Optics). Users may import STEP or IGES models (available upon request from HT technical documentation portal) to simulate mechanical constraints, clearance analysis, and thermal deformation under load. For audit-trail requirements in GxP environments, HT provides a Certificate of Conformance (CoC) with batch-specific metrology reports, including CMM validation data for critical dimensions—retained for 10 years per internal quality protocol.
Applications
- Construction of compact free-space optical paths for Raman spectroscopy excitation/detection arms
- Mounting substrate for fiber collimator arrays in telecom wavelength-division multiplexing (WDM) test benches
- Base platform for Michelson or Mach-Zehnder interferometer arms requiring sub-microradian angular stability
- Support structure for ultrafast laser beam transport systems where pulse dispersion must be minimized via rigid path definition
- Alignment reference for vacuum-compatible optical viewports and window mounts in UHV spectroscopy chambers (when paired with stainless-steel fasteners)
FAQ
Is the HTSB-B compatible with metric and imperial optomechanical hardware?
Yes. The dual-threaded hole pattern (M6 and 1/4″-20) ensures direct compatibility with both ISO-standard and ANSI-standard mounts, including those from Thorlabs (imperial) and Standa (metric).
Can the base plate be used in vacuum environments?
The bare anodized aluminum version is rated for low-to-medium vacuum (≤10⁻³ mbar). For UHV applications (<10⁻⁹ mbar), optional passivation or electropolished variants are available upon engineering consultation.
Does HT provide custom drilling or cutouts?
Yes. HT offers CNC customization services—including nonstandard hole patterns, cutouts for cable routing, or engraved fiducial marks—subject to minimum order quantity and NDA terms.
What is the maximum recommended load capacity?
Under uniform static loading, the HTSB-B (300 × 200 × 12 mm) supports up to 8 kg without measurable deflection (>1 µm) at center span, per ASTM E2920-13 bending modulus testing.
Is dimensional inspection data available for QA documentation?
Yes. A full CMM report (including GD&T callouts per ASME Y14.5-2018) is supplied with each shipment batch, traceable to NIM (National Institute of Metrology, China) standards.
