Optical Table Base Stand OTBS Series by ZOLIX

Overview

The OTBS Series Optical Table Base Stands are precision-engineered mechanical support structures developed by ZOLIX (Beijing Zolix Instruments Co., Ltd.) for building compact, cost-effective optical workstations. These stands operate on a passive mechanical support principle—providing rigid elevation and coarse height adjustment without active damping or pneumatic isolation. Each unit features a robust welded steel frame, integrated leveling feet with elastomeric vibration-absorbing pads, and standardized M6-threaded mounting interfaces aligned to the 25 mm pitch grid of ZOLIX’s OTBB-series ferromagnetic stainless steel breadboards. The OTBS system is not intended for high-sensitivity interferometry or nanometer-level stability applications; rather, it serves as an entry-tier solution for educational labs, prototyping benches, alignment stations, and QC environments where moderate mechanical stability and rapid reconfigurability are prioritized over sub-micron positional drift control.

Key Features

• Modular integration with OTBB-series breadboards via precise 25 mm grid-compatible M6 threading—enabling repeatable, tool-free component placement and repositioning.
• Height-adjustable variants (e.g., OTBS36-1 offers +30 mm fine-tuning range; OTBS66-1 provides −10 mm downward compensation) accommodate uneven floor surfaces or stacked optical layer requirements.
• Structural rigidity achieved through thick-walled steel tubing and reinforced corner welds—minimizing flexure under static loads up to 25 kg per stand (when used in quad configuration).
• Vibration mitigation via dual-stage elastomer feet: primary compression damping (Shore A 60) combined with secondary shear-decoupling geometry reduces transmission of low-frequency floor-borne disturbances (1–20 Hz).
• Corrosion-resistant finish: electrophoretic coating (E-coat) applied uniformly across all structural surfaces ensures long-term durability in ambient laboratory conditions.
• No electrical or compressed air dependency—fully self-contained mechanical operation requiring zero infrastructure integration.

Sample Compatibility & Compliance

The OTBS Series is designed exclusively for use with ZOLIX OTBB-series ferromagnetic stainless steel breadboards (e.g., OTBB36, OTBB66, OTBB69, OTBB612, OTBB1218). Breadboard compatibility is verified per ISO 9001:2015 manufacturing controls and conforms to dimensional tolerances specified in ZOLIX Technical Drawing No. OTBB-STD-2023. While the system does not comply with ISO 10816-1 (vibration severity standards for sensitive equipment), it meets GB/T 2423.10–2019 (Chinese national standard for basic environmental testing—mechanical shock and vibration). Units are CE-marked for EMC Directive 2014/30/EU (no active electronics) and RoHS 2011/65/EU compliant. Documentation includes full traceable material certifications (SS304 fasteners, Q235B structural steel) and assembly instructions aligned with GLP-aligned lab setup guidelines.

Software & Data Management

The OTBS Series is a purely mechanical hardware subsystem and contains no embedded electronics, firmware, or digital interfaces. Consequently, no software drivers, configuration utilities, or data logging capabilities are associated with this product. All dimensional specifications, load ratings, and installation procedures are provided in the bilingual (English/Chinese) Hardware Integration Manual (Rev. 4.2, 2024), which includes CAD models (STEP, IGES), torque tables for M6 fasteners (2.5–3.0 N·m), and recommended tightening sequences to preserve breadboard flatness. For laboratories operating under FDA 21 CFR Part 11 or ISO/IEC 17025, ZOLIX supplies a Device Installation Qualification (IQ) template compatible with standard lab validation workflows—covering physical verification of height tolerance (±0.2 mm), levelness (≤0.05° tilt), and interface repeatability (≤5 µm positional deviation over 10 insertion/removal cycles).

Applications

• Undergraduate optics teaching labs: rapid assembly of Michelson interferometers, laser cavity alignments, and polarization demonstrators.
• R&D prototyping benches: temporary mounting of diode lasers, photodetectors, and fiber collimators during proof-of-concept validation.
• Production line calibration stations: stable base for CCD-based measurement fixtures used in lens centering or beam profiling QA checks.
• Field-deployable spectroscopy enclosures: lightweight yet rigid foundation for portable Raman or fluorescence spectrometers requiring minimal footprint.
• Cleanroom-adjacent optical pre-alignment: non-outgassing steel construction and E-coat finish meet ISO Class 7 particulate cleanliness requirements when wiped with IPA.

FAQ

Can OTBS stands be used with non-ZOLIX breadboards?
Only breadboards featuring identical 25 mm M6-threaded hole patterns and ≥12 mm minimum thickness are mechanically compatible; however, magnetic retention and flatness assurance are guaranteed solely with OTBB-series units.
What is the maximum recommended payload per OTBS stand?
25 kg under static loading with uniform mass distribution; dynamic loads (e.g., motorized stages) require derating to 15 kg and consultation with ZOLIX Application Engineering.
Is height adjustment repeatable after multiple cycles?
Yes—micrometer-style threaded adjusters on OTBS36-1 and OTBS66-1 maintain ≤±2 µm repeatability over 500 adjustment cycles when lubricated per maintenance schedule.
Do OTBS stands require anchoring to the floor?
No anchoring is required for typical lab use; however, seismic-rated installations (IBC 2021 Zone 4) recommend optional floor-bolt kits (ZOLIX P/N: FBK-OTBS) for lateral restraint.
Are replacement elastomer feet available as spare parts?
Yes—ZOLIX part number EF-OTBS-R is stocked globally and certified for Shore A 60 hardness (ASTM D2240) with 10-year shelf life under controlled storage.
