| NAME |
NASA Reflectance Experiment Laboratory Nicolet 740 FT-IR Spectrometer
|
| TYPE |
Spectrometer
|
| DESCRIPTION |
The NASA Reflectance Experiment Laboratory (RELAB) Nicolet 740 Fourier-Transform infrared spectrometer with a biconical diffuse reflectance accessory was manufactured by SpectraTech. Using a globar IR light source, NIR range (1.5-4 um) is measured with PbSe detector and Mid-IR range (2-25 um) with DTGS detector, both using KBr beam splitter. Spectrometer interior and sample compartment can be purged with dry air. In addition to its built-in sample compartment, an environmental chamber built by William Patterson and Janice Bishop is attached, allowing Mars-like environment a small, yellow-color dome containing just one sample. The standard reference material is typically diffuse gold. The instrument has been decommissioned.
