Overview
The Thermo Scientific Nicolet Continuum Infrared Microscope is a high-performance, research-grade FTIR microspectroscopy system engineered for spatially resolved chemical identification and structural analysis at the microscopic level. It integrates Fourier Transform Infrared (FTIR) spectroscopy with precision optical microscopy, enabling simultaneous acquisition of high-fidelity infrared spectra and diffraction-limited visible-light images from the same sample location. The system employs an infinity-corrected optical architecture—pioneered in IR microscopes—to deliver collimated light paths across the entire optical train, minimizing spherical and chromatic aberrations introduced by conventional finite-conjugate designs. This design ensures consistent spectral fidelity and image sharpness regardless of auxiliary components (e.g., polarizers, interference filters, or beam splitters) inserted into the light path. Its coaxial visible-IR optical alignment guarantees pixel-perfect registration between visual morphology and spectral data—critical for correlative analysis in materials science, pharmaceuticals, forensics, and semiconductor failure analysis.
Key Features
- Infinity-corrected optical system with collimated beam path, eliminating wavefront distortion and enabling modular insertion of polarization optics and spectral filters without introducing optical aberration
- Patented Reflex Aperture dual-diaphragm design that suppresses stray light and diffraction artifacts, improving signal-to-noise ratio and spectral reproducibility
- True View™ dichroic imaging technology: real-time, overlay-enabled visualization of the IR measurement area during mapping or point-spectrum acquisition
- Coaxial visible/IR optical pathway ensuring sub-micron spatial registration between photomicrographs and spectral footprints
- Four-position objective turret accommodating interchangeable objectives—including variable and fixed-thickness compensation optics—for optimized performance across transmission, reflection, and ATR modalities
- Tri-view trinocular head supporting simultaneous visual observation, digital imaging, and video recording via C-mount interface
- Dual-detector capability: configurable for mid-infrared (MIR, 4000–600 cm⁻¹) and near-infrared (NIR, 12500–4000 cm⁻¹) detection using liquid-nitrogen-cooled MCT or room-temperature DTGS detectors
Sample Compatibility & Compliance
The Continuum microscope supports standardized sampling configurations per ASTM E1252-98 (Standard Practice for General Techniques for Infrared Microanalysis) and ISO 18387:2015 (Microspectroscopy — Requirements for FTIR microscopes). It accommodates solid, thin-film, and particulate specimens via transmission, reflectance (including specular and diffuse), and attenuated total reflection (ATR) modes—with dedicated ATR objectives featuring diamond, germanium, or silicon internal reflection elements. All operational parameters—including aperture size, step resolution, and detector integration time—are fully traceable and auditable to meet GLP and GMP documentation requirements. System software enforces user-access controls and electronic signature workflows compliant with FDA 21 CFR Part 11 for regulated environments.
Software & Data Management
Controlled by OMNIC Paradigm software, the Continuum platform provides integrated instrument control, spectral processing, hyperspectral mapping, and multivariate analysis (e.g., cluster analysis, PCA, spectral library searching). Mapping datasets support step sizes down to 1.0 µm with automated stage positioning and focus stabilization. All raw interferograms, processed spectra, metadata (including aperture settings, detector gain, background collection timestamp), and user annotations are stored in vendor-neutral HDF5 format. Audit trails record operator actions, parameter changes, and calibration events—enabling full traceability for ISO/IEC 17025 accreditation and regulatory submissions.

FAQ
What spectral range does the Continuum support in mid-IR mode?
The system operates from 4000 to 600 cm⁻¹ when equipped with a standard liquid-nitrogen-cooled MCT detector.
Can the system perform chemical imaging without moving the sample stage?
No—chemical mapping requires precise motorized X-Y-Z stage movement; however, the True View™ overlay enables real-time confirmation of measurement position relative to visible morphology.
Is ATR objective correction available for different sample thicknesses?
Yes—variable-thickness compensation objectives are offered to maintain optimal focus and coupling efficiency across diverse sample geometries and refractive indices.
Does the software support automated spectral library matching against commercial databases?
Yes—OMNIC includes built-in search algorithms compatible with the Sigma-Aldrich, Polymer, and Bio-Rad spectral libraries, with customizable match thresholds and hit quality scoring.
What is the minimum resolvable feature size under visible-light observation?
With 100× objective and Köhler illumination, the system achieves ≤0.2 µm lateral resolution in visible mode, conforming to Abbe diffraction limits.
