16) Imaging: Video camera option for ACT, it also gives a picture of the
measurement area on the PC monitor. Standard camera monochrome GigE
CCD camera with variable exposure time and gain control ≥ 1080 × 720
pixel, ≥ 12 bits, max ≥ 30 frames per second with 10, 20 and 50 x objectives.
Allowing real time images at variable angle of incidence (< 700).
17) Spectroscopic Measurements: Automatic setting up of optical components
and spectral display in standard energy (cm-1, eV) and wavelength ( , nm)
units for spectroscopic measurements.
18) Power requirement: should be maintained at 230 VAC single phase or 440
V three phase, 50 Hz.
19) Fitting options: Fast regressive fitting approach/algorithm with option
for Fit error, correlation matrix calculation with simultaneous graphical
display of experimental and calculated data.
B) Computers & Software:
