|
The Interspec 301-X series of FTIR portable spectrometers represent a low cost Fourier transform infrared and near infrared portable spectrometers and employ a number of unique features that ensure high performance from a compact instrument. The Interspec 301-X measures just 49 X 39 X 20 cm and is regarded as one of compact and versatile infrared FTIR spectrophotometers. The design of the 301-X is unique both in terms of optical design and the software and firmware designed specifically to significantly reduce overall analytical times.
The optical interferometer geometry is employing a new compact Michelson self compensating optical system that eliminates many of the optical alignment problems found in conventional type optical interferometers. The Interspec 301-X design avoids the use of conventional corner cube optics and dynamic alignment. In practice this means that the instrument can be used in the research laboratory, in any university or college environment and if required, can also be used outside laboratory or in remote locations.
Detector Options
The standard IR detector is a selected high sensitivity DLATGS pyroelectric design providing the highest possible signal to noise for all but the most demanding applications. However there are many applications in infrared spectroscopy where high resolution analysis is required for materials with high absorption characteristics and for these applications cryogenically cooled MCT detector options are available each with a specific wavelength range. In case of NIR spectral region two types of photodiodes are available: Si and InGaAs.
