Tender For Raman Spectrometer And Accessories 1. Spectrograph equipped with research grade microscope capable of producing Raman Spectra in the range of 100 cm to 4000 co 2. Spectrometer Range: 200 noi-2200 mm or higher using a single spectrometer. The eomplete instrument should be a single integrated unit without any fiber coupling 3 High throughput (30%), on axis, stigmatic Spectrometer with having refractive optics. 4 Spectral resolution (FWHM): 0.5 cm or better 5. Spatial resolution: 1 micron or better lateral and 2 micron axial 6. Scan-to-Scan repeatability between 0.01 cm or better (ut least 30 messurement) Spectrograph should allow continuous acquisition for the entire spectral Range to avoid any discontinuities while maintaining high resolution of soquisition (No Spectral Stitching allowed) or better during entire 8. Si 3 and 4 onder Raman bands should be with a signal to noise ratne better than 19:1 (3% order) and 3:1 (49 Order). 9. Gratings 2400 gr/mm (or better) mounted un encoder feedback-controlied stage without discontinuities at any given wavenumber. The gratings should be quickly and emily interchangeable without realignment 10. Adjustable confocal facility using motorized slit with automated signal optimization. 11. Set of Edge Filters 100 cm for 352 am 12. The spectorneter should be fitted with a filter wheel with neutral density filters offering 16 ur more diffimene power levels from 0.0005% or lesser) to 100% and should be software controlled. 13. Twu calibration sources Silicon and Neon light source for auto Validanon, auto calibration and imensity correction. Motorized Manual switching between laser and white light sample images using integral video 14. The lasers should be air cooled for maximal confocal performance and should be directly coupled to the spectrometer without any fiber coupling to the micriscope Air cooled, Diode Laser 532 mm, 50 mW so 100 mW 15. Upright Microscope branded research grade with color camera for viewing sample Microscope should be directly coupled to the spectrometer. Monocular head with color video camera. Objectives-5X, 20X, 100X 16. XYZ encoded motorized stage with step size 50 nm (or hester) in XY & 10 nm (or better) in 2 direction with Joystick/Track bull as well as computer controlled. Travel range of XYZ stage: 100 mm in X and 75 man in Y and 25 mm in Z or bigges 17. A multichannel Charge coupled device (CCD) detector: High efficiency thermoelectrically cooled COD. A fully automated multichannel detectors suitable for Raman measuremen Pixel Size. 20 µm x 20 µm with Pixels: 1024 x 256 Peltier cooled to 70°C or lower Quartum efficiency better than 40% Spectral Acquisition: 1000 spectra/sec. 18. The lasers should have their independent path of travel inside the spectrometer on the emission side. Set of beam expander optics and motorized pinhole should be provided for each set of lasers on the emission path to match the back aperture of the microscope objectives and to vary laser spot size on the sample. 19. Suitable PC (Operating optimized computer (minimum specification): 13 12th gen Dual core processor, 8 GB RAM, DVD-RW, I TB SATA SSD, Windows 10 (64 bit). 24 TFT Color Monitor) and Windows based data acquisition and analysis software. 20. Base plate for accommodating the system or Vibration Isolation table for housing the system. 21.3-years warranty on the system except laser laser should cover atleast one year warranty or 3000 working hours or more. 22. The system should have extra slots for upgrading with multiple lasers in future (at least one).
