The principle of measuring and recording diffuse reflection using SPECTRA VIR-1100 is based on focusing radiation by an ellipsoid mirror in an optomechanical module and a diffuse reflection module on the sample surface, followed by collection of residual radiation by a second ellipsoid mirror and its direction from an oriented flat mirror to the detector. The normalized primary signal is transmitted from the detector to the registration and control module, where it is processed in real time. The received information block of the registered spectrum (s) through the interface module enters the PC for further processing, analysis, systematization and storage by means of the software of the complex.
Key Features:
- option for measuring diffuse reflection of flat samples;
- spectral range 190 - 1100 nm (on request, extension to 2200 nm);
- wavelength setting error ± 1 nm;
- up to 4 programmable measurement and analysis modes with different levels of automation - from manual to automatic;
- search for archived spectral data by specified parameters;
- mathematical apparatus of elementary and extended functions for working with one spectrum or a set of them;
- import / export of results in common formats .txt, .csv ,. jpeg, TDMS, .xlsx, SQL.
- control of operating modes, registration and primary analysis in Real-Time mode in a digital module based on FPGA;
- presence of SMB-input / output for external synchronization of measurements by an external event (trigger);
- PC based on the operating system Windows 7 / 8.1 / 10/11;
- Serial USB / COM interface (upon GPIB request to interface with your equipment).
