Jingfei FLB1034 Reflectance Test Stand

Overview

The Jingfei FLB1034 Reflectance Test Stand is a precision-engineered optical mounting platform designed specifically for quantitative diffuse and specular reflectance spectroscopy in laboratory and R&D environments. It operates as a critical mechanical interface within fiber-optic-coupled reflectance measurement systems—enabling stable, repeatable positioning of samples relative to illumination and collection optics. The stand is optimized for integration with Y-shaped bifurcated fiber bundles (commonly 400–600 µm core diameter), where one arm delivers broadband or monochromatic light from a calibrated source (e.g., tungsten-halogen or deuterium lamp), and the other two arms collect reflected radiation for spectral analysis by a CCD- or CMOS-based spectrometer. Its modular architecture supports standardized SMA 905 connectors and maintains consistent working distance and incident angle alignment—key prerequisites for compliant reflectance quantification per ASTM E259, ISO 2813, and CIE 15:2018 guidelines.

Key Features

• Adjustable vertical height ranging from 0 to 200 mm in fine increments, enabling precise control over sample-to-fiber working distance and minimizing parallax-induced spectral distortion.
• Compact low-profile base (Ø200 mm × 20 mm) fabricated from anodized aluminum alloy for dimensional stability and electromagnetic compatibility, combined with a stainless steel central column for torsional rigidity and long-term repeatability.
• Tool-free quick-release mechanism for rapid detachment and repositioning of fiber holders and sample stages—reducing setup time during high-throughput material screening.
• Integrated alignment grooves and reference marks on the base plate to facilitate reproducible placement of calibration tiles (e.g., Spectralon® standards) and geometrically complex specimens.
• Optimized weight distribution and non-slip rubber feet ensure vibration damping and operational stability on optical tables or standard lab benches without additional clamping.

Sample Compatibility & Compliance

The FLB1034 accommodates flat, curved, or textured solid samples up to 150 mm in diameter and 50 mm in thickness—including powders in Petri dishes, coated panels, polymer films, ceramic substrates, and biological tissue sections mounted on glass slides. Its open-access design permits unobstructed access for auxiliary instrumentation such as contact angle goniometers or environmental chambers. All structural components comply with RoHS Directive 2011/65/EU and are free of cadmium, lead, mercury, hexavalent chromium, PBBs, and PBDEs. While the stand itself is not certified to IEC 61000-4 electromagnetic immunity standards, its passive metallic construction ensures minimal interference in spectrometer signal chains operating under GLP-compliant validation protocols.

Software & Data Management

As a purely mechanical accessory, the FLB1034 requires no embedded firmware or driver installation. However, it is fully compatible with industry-standard spectroscopic data acquisition platforms—including Ocean Insight OceanView, Avantes AvaSoft, StellarNet SpectraWiz, and custom LabVIEW or Python (PyVISA, NumPy, SciPy) implementations. When used in conjunction with NIST-traceable reflectance standards and calibrated light sources, the system supports full uncertainty budgeting per ISO/IEC 17025:2017 Annex A.3, including contributions from geometry repeatability (±0.15° angular deviation), height adjustment resolution (±0.5 mm), and thermal drift (<0.02 mm/°C over 20–30°C ambient range).

Applications

• Colorimetric evaluation of paints, inks, and automotive coatings per ASTM D2244 and ISO 11664-4.
• Quantitative analysis of pigment dispersion uniformity in pharmaceutical tablet coatings using UV-Vis-NIR reflectance mapping.
• In-line quality verification of anodized aluminum surfaces in aerospace component manufacturing.
• Non-destructive assessment of degradation kinetics in UV-stabilized polymer films exposed to accelerated weathering chambers.
• Calibration traceability chain development for portable field spectrometers deployed in soil science and agronomy studies.

FAQ

Is the FLB1034 compatible with UV-VIS-NIR spectrometers operating beyond 2500 nm?
Yes—the stand imposes no spectral limitations; compatibility depends solely on the fiber bundle’s transmission window and spectrometer detector response.
Can the base be mounted to an optical rail or breadboard?
Yes—four M4 threaded holes (pitch circle diameter 160 mm) are symmetrically distributed beneath the base for rigid kinematic mounting.
Does Jingfei provide calibration documentation or metrological traceability?
No—calibration of geometric parameters (height, angle, centering) must be performed in-house using laser interferometry or coordinate measuring machines per ISO 10360-2.
What is the maximum load capacity of the vertical column?
The column supports static loads up to 1.2 kg at full extension (200 mm) with ≤5 µrad angular deviation, verified per DIN 857-2 bending moment testing.
Are replacement fiber holders or custom-height extensions available?
Yes—Jingfei offers optional SMA-compatible fiber clamps (FL-HC series) and extended-height columns (FLB-EXT250) upon request with lead times of 4–6 weeks.
