LUMOS II

Fully automated FTIR imaging microscope

The LUMOS II is as an easy-to-use, stand-alone FTIR imaging microscope with peak performance in any measurement mode. Whether it is transmission, reflection or attenuated total reflectance (ATR), the LUMOS II is always the right choice. 

Features:

• Stand-alone FTIR microscope with full automation, very easy to use
• All in one - VIS, transmission, ATR and reflection
• Ultrafast data acquisition (1024 spectra at once) with superior focal-plane array (FPA) technology 
• No need of liquid nitrogen - thermoelectrically cooled MCT detector
• Motorized ATR crystal (ATR = Attenuated total reflection)
• Large working distance allowing sample space for sampling
• Macro sampling functionality for Macro samples
• RockSolid™ interferometer for permanently aligned optics and insensitivity to vibrations
• Fully automated test routines for validation according to cGMP (OQ, PQ)
• Pharma compliant - 21 CFR Part 11 and validation according to EU-, JP- and US-Pharmacopeia

Focal-plane array technology

The LUMOS II features incredibly fast FTIR imaging. Thanks to FPA technology, microscope is able to collect 1024 spectra in a single scan and therefore collection of over 50.000 spectra within a minute is not a fiction anymore. In such an FTIR image, every pixel can have down to 1.25 µm size and every pixel is composed of an entire FTIR spectrum. This spectral data can be used to render a color image, emphasizing a sample’s properties like chemical structure or composition. This results in a superb spatial resolution and peak sensitivity in all measurements modes.

Motorized ATR crystal

A major innovation is certainly the motorization of the ATR crystal in the objective. Due to this unique feature all IR measurements, even those in ATR mode, are performed fully automated with the LUMOS. An integrated pressure control ensures the constancy of the pressure applied from the crystal to the sample which is essential for mapping and imaging experiments. In transmission and reflection, the ATR crystal is hidden into the objective. For data acquisition in ATR the crystal is positioned into the IR focus by an encoded piezo drive.

Macro sampling

For the investigation of larger samples, a macro unit is available to be connected to the left side of the LUMOS. This unit allows the use of all QuickSnap^TM sampling modules of the compact FT-IR spectrometer ALPHA. Various QuickSnap^TM modules for transmission, diffuse and specular reflection as well as attenuated total reflection (ATR) provide sampling flexibility for almost all kinds of solid, liquid and gaseous samples.

RockSolid^TM interferometer

The permanently aligned Rocksolid^TM interferometer is a unique patented component which yields over 20% higher throughput than ordinary interferometer design. It benefits from dual retro reflection cube corner mirrors and wear-free pivot mechanism located in the center of mass, which ensures exceptional stability and reliability even in harsh environment. With its patented design, the elimination of mirror tilt optically and prevention of mirror shear mechanically is reached.

Advantages:

• No need of standby mode to protect the bearing
• No need of recalibration after movement
• No wearing of mechanical bearing, no spare parts, minimization of service costs
• Resistance to vibration and thermal effects
