CARACTERISTICI GENERALE
Modelul I-Spectrum 200-X de FTIR reprezinta o varianta eonomica a spectrometrelor cu transformanta Fourier si utilizeaza un numar de caracteristici unice care asigura o performanta ridicata din partea acestui aparat compact.
I-Spectrum 200-X si este considerat unul dintre modelele cele mai compacte (masoara doar 59 x 39 x 19 cm) si este usor adaptabil dintre spectrometrele IR FTIR.
Design-ul acestui model este unic, fiind creat special pentru a reduce semnificant timpul de lucru.
Geometria interferometrului utilizeaza un sistem optic compact Michelson cu autocompensare care elimina multe din problemele de centrare optica intalnite la tipurile de interferometre conventionale.
Design-ul I-Spectrum 200-X evita folosirea cuvelor optice cubice conventionale si alinierea dinamica.
In practica, acest lucru inseamna ca acest aparat poate fi folosit in laboratoarele de cercetare, in invatamant (universitati si licee) si daca se cere, poate fi folosit in afara laboratoarelor, pe teren sau in locatii mai indepartate. |

General View
The I-Spectrum 200-X series of FTIR spectrometers represent a low cost Fourier transform infrared spectrometers and employ a number of unique features that ensure high performance from a compact instrument.
The I-Spectrum 2000-X measures just 59 X 39 X 19 cm and is regarded as one of compact and versatile infrared FTIR spectrophotometers.
The design of the 200-X is unique both in terms of optical design and the software and firmware designed specifically to significantly reduce overall analytical times.
The 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 I-Spectrum 200-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 |
Detectorul standard este de tip DLATGS piroelectric, de inalta sensibilitate, creat pentru a furniza cel mai inalt semnal posibil pentru cele mai solicitate aplicatii.
Oricum exista multe aplicatii in spectrometria IR unde se cer analize de inalta rezolutie pentru materiale cu absorbanta inalta si pentru aceste aplicatii optiunile detectorului MCT (racire criogenica) sunt valabile fiecare pe un domeniu specific al lungimii de unda.
‡ In cazul regiunii spectrale NIR sunt valabile doua tipuri de fotodiode Si si iNgAaS. |
|
The standard 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. |
