Overview
The Hanting HT Series Stainless Steel Optical Posts are precision-engineered mechanical support components designed for stable, repeatable alignment and positioning of optical elements in laboratory and industrial optical setups. Constructed from high-grade austenitic stainless steel (typically AISI 304 or equivalent), these posts leverage cold-drawn bar stock and centerless grinding to achieve tight dimensional tolerances (±0.01 mm diameter control) and surface roughness values below Ra 0.4 µm—critical for minimizing micro-vibrational coupling and ensuring long-term dimensional stability under thermal cycling. Unlike aluminum alternatives, stainless steel provides superior resistance to creep, galling, and environmental corrosion—making the HT Series especially suitable for vacuum-compatible environments, cleanroom installations, and applications requiring non-magnetic or chemically inert structural components. Each post features a precisely machined 1/4″-20 or M6 threaded top and bottom (model-dependent), enabling secure integration with standard optical mounts, kinematic bases, and cage system adapters per ISO 80000-4 and ANSI/BHMA A156.5 standards.
Key Features
- Material integrity: Solid 304 stainless steel with full material certification (mill test report available upon request)
- Dimensional consistency: Ground shafts with ±0.01 mm diameter tolerance and straightness deviation < 0.02 mm/m
- Thread precision: ISO metric (M6) or UNC (1/4″-20) threads cut to Class 2B tolerance, verified by thread plug gauges
- Surface finish: Passivated per ASTM A967 for enhanced oxide layer uniformity and chloride resistance
- Modular compatibility: Interoperable with industry-standard optical mounts—including kinematic mirror mounts, lens holders, and translation stages from Thorlabs, Newport, and Standa
- Thermal stability: Coefficient of linear expansion ~17.3 × 10⁻⁶ /°C—well-characterized for interferometric and ultra-stable cavity applications
Sample Compatibility & Compliance
These posts are not sample-consumable devices but structural interface components; therefore, no sample loading or fluidic interaction is involved. Their compliance profile focuses on mechanical and environmental standards: RoHS 2011/65/EU compliant (Pb, Cd, Hg, Cr⁶⁺, PBB, PBDE restricted); REACH SVHC-free declaration available. For regulated environments, the posts meet the mechanical anchoring requirements referenced in ISO 10110-7 (optical element mounting) and support GLP-aligned optical bench configurations where traceability of mechanical interfaces is required. No FDA or IEC 61000-4 electromagnetic compatibility testing applies, as the component is passive and non-electric.
Software & Data Management
As purely mechanical hardware, the HT Series posts require no embedded firmware, drivers, or software integration. However, they are fully compatible with common optical design and alignment simulation platforms—including Zemax OpticStudio, FRED, and COMSOL Multiphysics—where users can import STEP or IGES models (available upon request) for mechanical tolerance stack-up analysis and thermal deformation modeling. Dimensional specifications are provided in both metric and imperial units in datasheets conforming to ISO 16792 for technical product documentation.
Applications
- Stabilizing high-finesse Fabry–Pérot cavities in gravitational wave detector prototype systems
- Supporting beam-steering mirrors in ultrafast laser amplifier chains (e.g., Ti:sapphire regenerative amplifiers)
- Constructing rigid, low-drift optical tables for white-light interferometry and surface metrology
- Mounting collimators and fiber launch optics in telecom wavelength calibration setups (C-band/L-band)
- Enabling reproducible alignment in undergraduate and graduate optics teaching labs per AAPT lab curriculum guidelines
- Serving as vertical supports in vacuum-compatible Raman spectroscopy sample chambers (up to 10⁻⁶ mbar)
FAQ
Are custom lengths or thread types available beyond the standard HTR model list?
Yes—custom machining for non-standard lengths (±0.5 mm increments), alternate thread standards (e.g., M4, 5/16″-18), or through-hole variants can be arranged directly with the manufacturer under NDA and minimum order quantity terms.
Do these posts meet UHV (ultra-high vacuum) outgassing requirements?
Standard posts are passivated and cleaned per ASTM A380 but are not baked-out. For UHV use (<10⁻⁹ mbar), optional vacuum-bake certification (200°C for 24 h) and residual gas analysis reports are available upon request.
Is dimensional inspection data supplied with each batch?
Batch-level CMM inspection reports—including diameter, length, thread pitch, and runout measurements—are provided for orders exceeding 50 units, traceable to NIM (National Institute of Metrology, China) standards.
