IdeaOptics P-TIP Series Fiber Optic Probes

Overview

The IdeaOptics P-TIP Series Fiber Optic Probes are engineered for high-fidelity spectral coupling in benchtop and process-integrated optical measurement systems. Designed around modular bifurcated and trifurcated fiber architectures, these probes serve as critical interface components between light sources, samples, and spectrometers—enabling precise spatial control of illumination and collection geometry. Each P-TIP probe implements a defined optical configuration optimized for a specific interaction mechanism: diffuse reflectance, transmission, solid-state fluorescence, liquid-phase fluorescence, or absorbance. The underlying principle relies on controlled numerical aperture (NA), core diameter, fiber material (typically UV-VIS fused silica), and angular alignment to ensure repeatable photon delivery and signal capture across 200–1100 nm. Unlike generic patch cords, P-TIP probes integrate mechanical stability, environmental shielding, and optical filtering directly into the probe head—minimizing stray light, polarization drift, and coupling loss during long-term operation.

Key Features

• Modular probe family covering five fundamental spectroscopic modalities: diffuse reflectance, transmission, solid fluorescence, liquid fluorescence, and absorption
• P-TIP-0045 variant features dual-bandpass filter integration: an excitation-side filter (center wavelength matched to source peak, ±5 nm bandwidth) and an emission-side longpass or bandpass filter (OD ≥6 at excitation wavelength) to suppress Raman and Rayleigh scatter
• Stainless-steel or anodized aluminum probe housing with IP54-rated sealing for dust resistance and mechanical robustness in shared lab environments
• Standard SMA 905 connectors compatible with industry-standard spectrometers (e.g., Ocean Insight, Avantes, Hamamatsu) and broadband or LED/Laser sources
• Interchangeable tip geometries—including flat-polished, angled (8°), and collimated configurations—to accommodate curved surfaces, confined spaces, or collimated beam coupling
• Calibration-ready design: probe-to-probe spectral response variation < ±3% across batch (measured against NIST-traceable tungsten-halogen standard)

Sample Compatibility & Compliance

P-TIP probes support non-destructive, contact or near-contact measurements on solids (powders, films, tablets, painted surfaces), liquids (aqueous/organic solutions, suspensions), and semi-solids (gels, pastes). The P-TIP-0045 is validated for solid fluorescence applications including pharmaceutical tablet coating uniformity, polymer additive distribution, and mineral identification. All probes comply with IEC 61326-1 (electromagnetic compatibility for laboratory equipment) and meet RoHS 2011/65/EU material restrictions. Filter specifications adhere to ISO 10110-7 for surface quality and spectral edge steepness. For regulated environments, probe serial numbers, filter lot traceability, and factory calibration certificates are provided per unit—supporting GLP documentation requirements and audit readiness.

Software & Data Management

While P-TIP probes operate passively, their performance is fully leveraged through spectral acquisition software that supports hardware-triggered synchronization, dark/baseline correction protocols, and spectral ratioing (e.g., R = I_sample/I_reference). When integrated with IdeaOptics’ OmniDriver SDK or third-party platforms (e.g., MATLAB Instrument Control Toolbox, Python’s seabreeze), users can script automated probe-switching sequences, multi-point mapping routines, and real-time spectral feature extraction. Raw intensity data is exported in standardized formats (CSV, HDF5) with embedded metadata—including probe model, filter specs, fiber NA, and acquisition timestamp—ensuring FAIR (Findable, Accessible, Interoperable, Reusable) data practices required under FDA 21 CFR Part 11 for electronic records.

Applications

• Pharmaceutical QC: Tablet coating thickness assessment via diffuse reflectance; API crystallinity monitoring using NIR absorption
• Materials science: Quantum dot photoluminescence quantum yield (PLQY) quantification in solution and thin-film states
• Food & agriculture: Grain moisture content estimation from NIR absorption bands; fruit bruise detection via chlorophyll fluorescence decay kinetics
• Environmental analysis: In-situ water quality monitoring (COD, nitrate, dissolved organic carbon) using UV-Vis absorption probes
• Academic research: Time-resolved fluorescence lifetime measurements with gated CCD or TCSPC systems

FAQ

Can P-TIP probes be used with pulsed lasers?
Yes—provided pulse energy remains below 10 µJ/pulse at 1064 nm and average power does not exceed 500 mW to avoid fiber end-face damage.
Is spectral calibration included with each probe?
A relative spectral responsivity curve (200–1100 nm) is supplied with every P-TIP-0045 unit; absolute NIST-traceable calibration is available as an optional service.
What is the maximum operating temperature for continuous use?
Standard P-TIP probes are rated for ambient operation up to 60°C; high-temp variants with polyimide-coated fibers support 150°C for industrial process monitoring.
Do you offer custom fiber core diameters or NA configurations?
Yes—custom designs include 50/100/200 µm core diameters, NA 0.22–0.37, and hybrid multimode/single-mode bundles for coherence-sensitive applications.
How is probe-to-probe reproducibility verified?
Each production batch undergoes statistical process control (SPC) using a reference spectrometer and stabilized halogen source; CpK ≥1.33 is maintained across key parameters (insertion loss, angular acceptance, filter cutoff fidelity).
