Overview
The PerkinElmer Spotlight 400/400N is a high-performance laboratory Fourier Transform Infrared (FT-IR) imaging system engineered for spatially resolved molecular characterization of heterogeneous samples. Unlike conventional point-mapping or focal-plane array (FPA)-based systems, the Spotlight 400 leverages a proprietary linear array mercury cadmium telluride (MCT) detector architecture—comprising 16 individually gold-wired, narrow-band elements integrated with a broadband mid-band reference detector on a single cryogenic substrate. This design eliminates mechanical repositioning, pixel dropout, and spectral range compromise inherent in FPA systems. The instrument operates on the principle of interferometric spectral acquisition synchronized with precision motorized stage translation, enabling true simultaneous collection of high-fidelity spectral data across defined spatial coordinates. Its core capability lies in delivering quantitative chemical mapping at micron-scale resolution without sacrificing spectral breadth (up to 720 cm⁻¹), signal fidelity, or acquisition speed—making it uniquely suited for R&D laboratories, quality control environments, and regulatory-compliant material forensics where trace-level compositional heterogeneity must be resolved under controlled, reproducible conditions.
Key Features
- Patented linear array MCT detector with 16 parallel sensing elements—enabling full spectral coverage (up to 720 cm⁻¹) at maximum sensitivity and zero dead-time between spectra
- Imaging speed of up to 170 high-SNR spectra per second, significantly exceeding conventional step-scan or FPA-based FT-IR imagers
- Adjustable spatial sampling: selectable pixel sizes of 1.56 µm (via Imaging ATR), 6.25 µm, 25 µm, and 50 µm—supporting both high-resolution microanalysis and rapid survey scanning
- Integrated motorized XYZ sample stage with <0.001% positional repeatability and real-time synchronization to interferometer mirror motion (up to 5 direction reversals/sec)
- No moving optical components during acquisition—detector and stage architecture ensures long-term calibration stability and minimal maintenance
- Single-click detector mode switching between narrow-band (high SNR) and broadband (extended range) configurations—no hardware recalibration required
- Imaging ATR accessory for direct contact analysis of opaque, highly scattering, or low-reflectivity samples—including polymers, biological tissues, and pharmaceutical tablets
- Multi-region acquisition protocol allowing independent parameter definition for up to 99 discrete fields-of-view within one experiment sequence
Sample Compatibility & Compliance
The Spotlight 400/400N supports diverse sample forms—including thin sections, bulk solids, powders, films, coatings, and hydrated biological specimens—without requiring conductive coating or vacuum compatibility. Its Imaging ATR module enables non-destructive surface interrogation of irregular or fragile samples that cannot be mounted conventionally. The system complies with key international standards governing analytical instrumentation validation and data integrity, including ASTM E1252 (Standard Practice for General Techniques for Infrared Quantitative Analysis), ISO 18384 (Microspectroscopy—Requirements for FT-IR Imaging), and USP (Infrared Absorption Spectrophotometry). When operated with PerkinElmer’s Spectrum Touch™ software configured for audit trail and electronic signature, the platform meets FDA 21 CFR Part 11 requirements for regulated environments. Full GLP/GMP documentation packages—including IQ/OQ/PQ protocols, calibration certificates, and uncertainty budgets—are available upon request.
Software & Data Management
Controlled via Spectrum Touch™ software, the Spotlight 400/400N provides an intuitive, workflow-driven interface for method development, acquisition scheduling, and multivariate image processing. All raw interferograms and processed spectra are stored in vendor-neutral, self-documenting HDF5 format—with embedded metadata covering instrument configuration, environmental conditions, user identity, and timestamped audit logs. Built-in chemometric tools include hierarchical cluster analysis (HCA), principal component analysis (PCA), and spectral unmixing algorithms optimized for IR hyperspectral cubes. Data export supports CSV, ASCII, and JCAMP-DX formats for third-party integration with MATLAB®, Python (SciPy/NumPy), or commercial LIMS platforms. Optional Spectrum Quant™ module enables validated quantification workflows compliant with ISO/IEC 17025 requirements for accredited testing laboratories.

FAQ
What distinguishes the Spotlight 400’s linear array detector from conventional FPA detectors?
The linear array eliminates frame averaging, pixel dropouts, and spectral truncation—delivering full spectral range at maximum sensitivity per scan, with no trade-off between speed and resolution.
Can the system perform quantitative analysis across multiple sample regions in a single run?
Yes—multi-region acquisition allows independent parameter sets (e.g., resolution, scan number, aperture) for up to 99 locations, all executed unattended.
Is Imaging ATR compatible with hydrated or temperature-sensitive samples?
Yes—the ATR crystal maintains ambient thermal equilibrium; no heating or drying is required, preserving native sample state.
How is calibration traceability maintained over time?
Wavelength and photometric calibration are verified using NIST-traceable polystyrene film standards; automated daily checks ensure ongoing compliance.
Does the system support remote operation and data review?
Spectrum Touch™ supports secure remote desktop access and web-based spectral image viewing via PerkinElmer’s cloud-enabled Connect Portal.
