Source
Xenon lamp is used as light source for a standard models. Source can be changed to tungsten halogen or to a combination of deuterium and tungsten-halogen depending upon the application.
Entrance Slit
Entrance slit is micrometer driven with 10 micron resolution and 1 micron sensitivity. Slit width can be adjusted from 0-3 mm. The slit is manually adjusted and locked in position for the experiment.
Excitation Monochromator
Excitation Monochomator has Czerny-Turner design with all the features of our standard device described as model : spectra-UV-VISINR . The device incorporates a plane holographic grating with 1200 lines/mm and precision motorized sine drive mechanism. Collimating optics used are concave mirrors to minimize aberrations as far as possible.
Sample Chamber
Sample chamber in the instrument is designed for accommodating 10 mm standard cuvettes. The chamber can be customized on request.
Emission Monochromator
Emission monochromator has similar specifications as that of excitation monochromator. It uses plain holographic grating with motorized wavelength drive mechanism for scanning. Motor used is stepper motor driven in micro-step mode. Collimating optics used are concave mirrors with UV enhanced coating.
Detector
The detector is highly sensitive Photo Multiplier Tubes (PMT) with integrated drive electronics to minimize electronic noise.
Control Electronics
Control electronics takes care of scanning functions of excitation and emission monochromators along with source and detector. Communication with computer is USB based.
Software
The instrument is fully computer based with all operating commands given from the computer. The UI of the dedicated software is made as user friendly as possible. Data is saved in the computer in standard formats.
