LUMOS FT-IR Microscope
LUMOS is a fully automated stand-alone FT-IR microscope. It combines best performance for visual inspection and infrared spectral analysis of micro samples with highest comfort in use.
Due to the motorization of all moveable components including the ATR-crystal, the LUMOS provides an unmatched high degree of automation. All required changes of hardware settings as well as the complete IR-measurement procedures are performed fully automated – even in ATR-mode.
The intuitive software guides the operator step-by-step through the process of microscopic sample analysis. At each step the user interface only provides the appropriate functions to proceed. The measurement results in a single file including visible images, spectral data and sample information. For evaluation and visualization of the microscopic data the software provides powerful and intuitive Chemical Imaging functionality.
Although the LUMOS is designed to be operated by non-experts for routine applications its exceptional sensitivity makes it also very suitable for high demanding applications.

FT-IR microscopy with full automation
The LUMOS is a stand-alone FT-IR microscope with an integrated
FT-IR spectrometer perfectly matched into its optical design. All components are motorized and electronically coded. The innovation of a motorized ATR-crystal allows the system to switch from transmission or reflection to ATR mode without interaction of the operator, and to measure fully automated sample and background spectra even in ATR mode.

The LUMOS includes an 8x objective which is used in transmission, reflection and ATR mode. The optics of the LUMOS is specifically matched to this objective resulting in a high imaging quality without field curvature distortion. To achieve a high depth of field for the visual inspection of a sample, but also highest sensitivity for the IR analysis, the applied numerical aperture is automatically changed between IR and Vis mode.

Powerful FT-IR technology
The heart of each FT-IR spectrometer is the interferometer. The LUMOS uses a patented, permanently aligned RockSolid
TM interferometer being extremely insensitive against mirror tilts, vibrations and thermal effects.
Permanent aligned cube corner interferometer for highest stability
Gold coated mirrors for highest efficiency
All IR-transparent windows and the IR beam splitter are made of ZnSe providing robustness even against high humidity
Infrared light source with long life time (> 5 years)
Solid state laser with long life time (>10 years)
High sensitive photoconductive MCT detector; DTGS detector as option
The LUMOS is very compact needing less lab space than conventional FT-IR microscopes. Yet it provides extraordinary large space between objective and stage giving room for samples with up to 40mm thickness. Due to an unobstructed access to the planar sample stage the sample positioning is extremely convenient.
Although the LUMOS is a stand-alone FT-IR microscope it also provides the option to analyze larger samples using the MACRO UNIT connected to the left side of the LUMOS. The MACRO UNIT allows the use of all QuickSnap
TM sampling modules of the compact FT-IR spectrometer ALPHA thereby providing sampling flexibility for almost all kinds of solid, liquid and gaseous samples.
VIDEO Wide application range
LUMOS provides high quality data as well in visualization as in IR-analysis even at high spatial resolution thereby opening a wide range of possible applications. The identification of tiny particles or surface contaminations is crucial to find the reason for product failures, a task relevant for practically all industries.
In forensics the analysis of fibers, chemical residues and varnish pieces can provide evidence in criminal cases. Also the IR-microscopic examination of ink on paper is a helpful approach to identify counterfeit documents and bank notes. The chemical composition of inhomogeneous structures like multilayer polymers, paintings or biological tissues can be visualized applying the mapping technique. This gives access to a multitude of applications in industrial R&D and academic research.
