Tender For Dual-Line Camera Spectrometer System With High-Speed Data Acquisition Electronics, Bangalore-Karnataka

Tender For Dual-Line Camera Spectrometer System With High-Speed Data Acquisition Electronics 1 The proposed setup should be a turnkey system to measure the pump induced absorbance change measurements in a pump-prob geometry. Provide all necessary hardware and software for integrating with the existing ultrafast amplified laser system running at minimum 30 kHz. 2 The setup should include the following: (a) One prism spectrograph with visible prisms and achromatic lenses. (b) Should have two-line CCDs attached to the spectrograph. The line CCDs must have 1024 pixels, at least 30 kHz readout, active area: 24.5x1.4mm, range: 200-1000 nm. Nearly 100 kHz single trigger on 2 interfaces, at least 30 kHz on 1 interface. The sensor should be specifically designed for low light-level detection to be used as a linear image sensor having a long aperture in the direction of the device length. Nearly 90% quantum efficiency around 600 nm, low readout noise and wide dynamic range with excellent (≥35%) UV sensitivity. (c) PCIE interface with two chopper inputs. (d) Win driver (64 bit) with LabVIEW examples. 3 The setup should meet the following specifications: i. Able to capture at least 30,000 spectra per second. ii. Overall rms noise <9 counts on a 14 bit scale (0..16000) @ max line rate of 100 kHz iii. The AD converter should have at least a 14-bit scale from zero up to 16000 counts. iv. 64-bit data handling without extra RAM (all RAM of PC is used). vi. The software should have 2 windows to allow the active spectrograph and detector signal to be displayed. v. 2 chopper input triggers for synchronized data storage (i.e., start always on chopper open) vi. storage of additional integrated reference channel’s CCD signals synchronously to each shot for correction of fluctuations. vii. The cameras should be expandable to 4 cameras parallel exposure mode to build an I/I0- detection system for each wavelength range. This 4-camera setup should also be able to reach the 10 kHz single trigger rate. viii. The cameras should be able to work with a distance to the PC of up to 10m. Preferred is a fiber cable connection for better EMC (electro-magnetic compatibility). ix. The system should be expandable to measure additional signals synchronously to the spectra - like delay stage positions. 4 Required all-inclusive service warranty of the hardware for one year from the date of receipt of the instrument and online assistance for three subsequent years. 5 Should specify all the finer details of terms of warranty for the various components used in the overall instrument assembly.
