The LUMOS is a stand-alone microscope with an FTIR spectrometer perfectly integrated into its optical design. Due to the motorization and networking of all moveable components inside the LUMOS, the system provides a high degree of automation for maximal comfort in use. The LUMOS includes an 8x objective which is used in transmission, reflection and ATR mode.
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.
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 QuickSnapTM sampling modules of the compact FT-IR spectrometer ALPHA. Various QuickSnapTM 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.
The permanently aligned RocksolidTM 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.
