FR-Basic tools have been carefully designed to be assembled by modules. Each FR-Basic tool is made by five modules

  • Core Unit,
  • Case Type,
  • Optical Fiber Configuration,
  • Working Area and
  • Cover Top.

Furthermore there is an Extensive Series of Accessories. By choosing or combining different modules one can make the most suitable characterization set-up for any end-user needs. The various options available for each of the building blocks are illustrated in the figure below.

 Core Module options

In Core Unit, the end-user defines the spectral range of interest. The Core Unit houses a Miniaturized PC-driven High Performance Spectrometer, a suitable light source and all the necessary power sources and controllers. The light emitted from the Light Source and the light to be analyzed by the spectrometer, are delivered through optical fibers.

The light source has been carefully designed in order to provide high stability emission spectrum, software and manual controlled light intensity, and very long operation times. The Core Unit case is manufactured from high quality industrial anodized aluminum elements offering a robust and modular construction. The Core Unit is available in several configurations with most typical to be: UV/VIS or VIS/NIR spectrum with standard spectrometer, UV/NIR spectrum with High resolution spectrometer, UV/NIR or VIS/NIR spectrum with scientific grade (cooled) spectrometer, NIR spectrum with NIR spectrometer and D with two spectrometers for combined measurements in extended VIS/NIR spectrum. Every FR-Basic tool is supplied with FR-Monitor software that can control and take advantage of the characteristics of all features of FR-units.

* Thickness measurement range depends on the spectral and refer to a single film layer with refractive index ~1.5 over a reflective substrate.

Case Module Options

Type A

In this case the optical connections are in the front panel for optimum spectrometer's sensitivity. When this option is selected, Cover Top can not be used.


Type B

In this case the optical connections are located on the back top of the case. This configuration supports all accessories and thus offers increased modularity of the unit.
